  • An assessment of the quality of effluent discharged from several
           wastewater treatment plants into the Crocodile River of Mpumalanga, South
           Africa

    • Abstract: The effluents from the South African wastewater treatment plant systems have a detrimental effect on the country's water resources and public health. Municipal wastewater services are often considered inadequate when compared to national standards and inter-national benchmarks. The objective of this study was to evaluate the quality of wastewater effluent discharged from multiple sewage treatment facilities throughout the Crocodile River catchment area in the Lowveld. The quality of wastewater effluent was tested at nine wastewater discharge stations along the Crocodile River. Samples were collected monthly during the eight-month duration of 2021. Samples were analyzed by the South African National Accreditation System (SANAS) laboratory and statistical analysis was conducted using the Seaborn program. The results indicated that almost all the sampling sites had very high suspended solid concentrations in their effluent discharges; the highest was recorded at Kanyamazane site with 26,20 mg/L, and the lowest at Kabokweni with 7,2 mg/L. High levels chemical oxygen demand (COD) were recorded, which increased nitrate levels. High COD is an indication of water treatment system inefficiency. In most cases, the levels of E. coli were within the legal required limits, except for Kabokweni (192425)/100 mL) and Hectorspruit (1183/100 mL). R2= 0.83 showed a strong association between suspended particles and ammonia nitrogen (NH3-N). Pollution of the Crocodile River is mostly due to wastewater treatment facility failure; therefore, the South African government should invest in wastewater treatment and sludge management technology. Funds should be utilized efficiently for infrastructure development and maintenance.
       
  • Assessment of groundwater vulnerability in Webuye Municipality, Kenya

    • Abstract: Access to safe water and sanitation is a basic human right and is enshrined in the sustainable development goal 6. Consequently, resources have been channeled towards development and improvement of water sources. Unlike surface water, the demand for groundwater is increasing due to its preserved quality, affordable development capital and drought resilience. Population density has resulted into entry of pollutants into aquifers because of reduced distance between the pollutants and groundwater sources, human activities and hydrogeological conditions. The aim of this study was to carry out an assessment of groundwater vulnerability to contamination as a preventive approach. Webuye town is a service area of Nzoia Water Services which provides water and sewerage services. However, water and sanitation coverage in Webuye town still below 50%, a portion of residents rely on onsite sanitation systems and groundwater. This is due to costs of installation, topographical challenges and limited pipeline extensions. It was observed that areas where groundwater sources are predominantly used, human waste is managed onsite close to groundwater abstractions points. The methods used in this study included the application of DRASTIC model which was interfaced in ArcGIS version 10.3. Inverse distance weighted (IDW) interpolation technique was used to produce vulnerability maps. The model inputs were seven: depth, recharge, aquifer, soil properties, topography, impact of the vadose zone, hydraulic conductivity and Land use. The results show that North Eastern areas of the study area; Maraka (Township) and Muchi scored the highest DRASTIC-LU values, implying high chances of groundwater vulnerability to contamination. The shallow water table, groundwater recharge, the type of soil, slope and the land use activities in the study area resulted into increased vulnerability. The findings should inform the municipality management on water quality precautions to be undertaken while developing groundwater sources in the area and development of pollution control framework.
       
  • Sorbitol MacConkey agar and wastewaters` coliphages

    • Abstract: A total of 114 samples collected from hospital wastewaters and rivers in Addis Ababa, Ethiopia were tested for non-sorbitol fermenting bacteria and coliphages. Sorbitol MacConkey agar is mainly used in the detection of E. coli O157:H7. However, other emerging diarrhoeagenic enteropathogens such as Plesiomonas shigelloides, Edwardsiella tarda, Providencia alcalifaciens, Escherichia albertii, Escherichia vulneris and Escherichia fergusonii were detected in the samples using this medium. Information for most of the emerging enteropathogens is scarce in most countries including Ethiopia. A total of 20 different genera, 38 species of non-sorbitol fermenting bacteria were isolated. Escherichia coli O157 could not be detected from any of the samples. All these backgrounds may mask the detection of Escherichia coli O157. Even if sorbitol MacConkey agar has several background limitations, different emerging diarrhoeagenic non-sorbitol fermenting bacteria were detected in the majority of the rivers and hospitals` wastewaters samples. The correlation between coliphages and non-sorbitol fermenting bacteria were not significant. As several bacteria have been isolated on sorbitol MacConkey agar medium, it is essential that the most selective laboratory techniques will be desired for outbreak investigation of E. coli O157, but other non-sorbitol fermenting enteropathogens should also be detected using sorbitol MacConkey agar in low resources countries.
       
  • AI-enhanced flood forecasting: Harnessing upstream data for downstream
           protection

    • Abstract: This research devised a cutting-edge artificial intelligence methodology to enhance flood forecasting in Quebec, Canada, an area frequently affected by floods. The core of this project was creating a novel artificial intelligence (AI) model (i.e., Generalized Structure of Group Method of Data Handling) dedicated to the early detection of potential flood events. Utilizing data from two key hydrometric stations, Saint-Charles and Huron, located within the region, the study aggregated data from 15-minute intervals into comprehensive hourly averages. An initial analysis sought to understand the relationship between river flow rates and the environmental factors of temperature and precipitation upstream and downstream. The investigation uncovered intricate relationships among these factors, presenting challenges in accurately predicting floods. To address this, a specialized AI model was developed to translate the flow data from the Huron station to predict potential flooding at the Saint-Charles station. This model, leveraging 48-hour lag data from upstream, was designed to forecast flood events at the Saint-Charles station with lead times ranging from one to eighteen hours. The model demonstrated significant predictive accuracy, with a correlation coefficient surpassing 0.9. Consequently, this innovative AI model emerges as a promising tool for improving Quebec's flood prediction and early-warning systems.
       
  • Gradual pumping through filtration sleeves: An approach for extracting
           narrow contaminant enclaves in groundwater

    • Abstract: Low-energy extraction wells fitted with filtration sleeves were numerically modeled to assess their capability to extract narrow contaminant plumes in a hypothetical unconfined aquifer beneath a lined landfill. After 2,000 days, the source was shut off and remediation simulations commenced. A sleeved submersible pump extracting 0.4 m3/day in a well near the downgradient edge of the plume, coupled with an upgradient well injecting the same rate, effectively contained and removed the plume. Adding non-pumped filtration wells upgradient of the extraction well marginally improved containment and remediation timeframe. At some sites, low-energy, sleeved extraction wells may be useful for extracting narrow plumes emerging from contemporary landfills.
       
  • Treating gray water by anaerobic digestion in order to use in landscape
           irrigation

    • Abstract: Wastewater output has increased considerably as a result of global population growth. Efforts to manage wastewater are expanding globally. Bio-based methods are useful and effective for treating a wide range of wastewaters, especially those from homes. In this research, the gray water stream at Sari Agricultural College in the north of Iran was treated using an anaerobic biological method. The purpose of this study was to determine whether using treated gray water for landscape irrigation was feasible or not. A fine screening pre-treatment system and a septic tank system were created in order to achieve this goal. After the first stage screening of superfluous solid components, anaerobic digestion was carried out for 26 hours at a temperature of between 14 and 16 °C in a 5 m3 septic tank. Treatment method function was revealed by measuring and comparing the pollutant indices with the permissible rates. The obtained data were: BOD 19.5 mg/L, COD 185 mg/L, Suspended Solid (SS) 90 mg/L, Organic Matter (OM) 80 mg/L, NO3 26 mg/L, PO4 6.25 mg/L, Oil and Grease (O&G) 9.3%, pH 5.9-7.1. The permissible rates for these indices are 100, 200, 200, 300, 30, 6.75, 10, and 6.8-7.1, respectively. The treated gray water was allowed to be utilized as irrigation water. After irrigating, the landscape did not face any negative effects. Nonetheless, the high acidity was owing to the detergents in effluent and this was the main reason provides a vast range of microelements leading to poisoning plants in a long period.
       
  • Investigation of the effective parameters on the phenol removal from the
           groundwater by response surface method

    • Abstract: The discharge of industrial waste containing organic pollutants like phenol has caused a surge in environmental complications in water, soil, and air. In recent years, the concentration of phenolic pollutants has risen due to their high toxicity and environmental persistence. This research used geotextile/activated carbon (GTX/AC) adsorbent to purify groundwater contaminated with phenol, owing to its easy availability. A low-cost geotextile carrier was utilized to avoid the dispersion of active carbon in the groundwater. Response surface method (RSM) was used in the present research to design and optimize experimental tests. The results indicate that the initial concentration, pH, and adsorbent dosage are the most significant parameters affecting the geotextile/activated carbon (GTX/AC) adsorbent performance. Maximum adsorption capacity was considered the highest desirability level for the response surface method optimization. The initial phenol concentration equal to 458.8 mg/L, the amount of pH equal to 7, and the dose of adsorbent equal to 5.5 gr were the best conditions for removing phenol from the water. Based on the result of this research, the response surface method can be used for modeling and optimizing phenol adsorption from groundwater, and geotextile/activated carbon (GTX/AC) adsorbent is a suitable choice for the treatment of water polluted with phenol.
       
  • Synthesis and optimization of biochar prepared from cow dung for methylene
           blue removal

    • Abstract: Cost-effective dye wastewater treatment approaches are critically required for the long-term sustainability of textile industries. To fill the gaps, multiple high-potential adsorbents derived from biomass have been proposed. For this purpose, this study was conducted to present an applicable and cost-effective biochar synthesized from cow dung to remove methylene blue from the aqueous solutions. The potential of cow dung-based biochar was optimized under various pH, biochar dose, methylene blue concentration, contact time, and temperature. The maximum removal was 96% achieved at optimum conditions, 20 mg/l methylene blue concentration, 0.2 g biochar dose, pH of 6, and 90 min contact time at ambient temperature. The methylene blue adsorption process followed the Freundlich isotherm (R2=0.9827) and pseudo-second-order (R2=0.999) kinetic models, implying multilayered adsorption on the heterogenous surface and chemisorption mechanism, respectively. Furthermore, the adsorption process was spontaneous and exothermic due to negative Gibbs free energy (ΔG0) and enthalpy (ΔH0) with the reduction at randomness of methylene blue molecules and adsorbent interaction based on negative entropy (ΔS0). Regarding the high efficiency of cow dung-based biochar to adsorb methylene blue, it is recommended that further investigations consider the biochar activation and functionalization intending to upgrade its adsorption capacity.
       
  • Removal of Hg and Pb in aqueous solution using magnetite carbon dots
           nanocomposite

    • Abstract: Hg and Pb metals are major concerns because of their high degree of toxicity in public environment, which also pollute aquatic systems. Nanocomposite adsorbents have been developed for cleaning polluted water at low. The study aims to determine the removal efficiency of magnetite carbon dots nanocomposite in case of Hg and Pb in the aqueous solution. In this paper, magnetite carbon dots (symbolized as Fe3O4/CDs) nanocomposite was synthesized through a two-step process of co-precipitation and pyrolysis methods. The synthesized nanocomposite was analyzed using Utraviolet visible (UV-vis), Fourier transform infrared spectroscopy (FTIR), scanning electron electron microscopy (SEM), electron dispersive X-ray fluorescence (EDXRF), X-ray diffraction (XRD) and atomic absorption spectrophotometer (AAS). According to the results, the synthesized (Fe3O4/CDs) nanocomposites were found to be 20 nm in diameter, superparamagnetic property, surface roughness and deformations, important functional groups, iron-rich nanocomposite and favorable removal efficiency for Hg (82.70 %) and Pb (72.91 %), respectively. Therefore, the results indicated that these Fe3O4/CDs nanocomposites are potentially attractive agents for the removal of heavy metals ions, especially Hg and Pb from industrial wastewater.
       
  • Adsorption potential of biochar derived from cotton waste for efficient
           removal of methylene blue from aqueous solutions

    • Abstract: Agricultural product processing generates substantial quantities of agricultural waste and their disposal has become a critical concern, threatening human health and the environment. The pyrolysis process is an upgrading technology for producing valuable products from waste feedstocks. Hence, the potential of eco-friendly biochar derived from cotton waste was comprehensively investigated for methylene blue removal. The cotton-based biochar contained various pore sizes and functional groups on the surface verified by SEM and FTIR analyses. The impacts of adsorbent dose, methylene blue concentration, temperature, pH, and contact time on the adsorption of methylene blue were assessed to highlight the efficiency of the cotton-based biochar. The results revealed >90% removal under 10 mg/l methylene blue concentration, 0.7 g adsorbent dose, pH of 6, and contact time of 60 min at a temperature of 20 ⁰C. The adsorption isotherm was well-fitted with the Freundlich model, indicating the multilayer methylene blue adsorption. The adsorption process was chemisorption and endothermic based on kinetic and thermodynamic modeling. Summing up, it can be suggested that the cotton-based biochar can be easily and efficiently applied for methylene blue removal from aqueous solutions, and further investigations are required to modify its specific surface area by a green synthesis approach.
       
  • Modeling the effects of changes made in Sistan's water resources system
           using WEAP

    • Abstract: Water is one of the most basic environmental resources and plays an important role in human life. The Sistan river is the only source of water supply in this area and is completely dependent on the border river of Hirmand. The water of this river fluctuates greatly due to the interference of the country of Afghanistan, climate changes and the existence of Hamon international wetland, which has made the issue of decision-making regarding the management of water resources in Sistan region more than in other regions. This study, using the WEAP model, deals with modeling the effects of changes made in the water resources system in the Sistan region, which has special weather conditions. The results of this study showed that policies implemented in recent years have a positive effect on increasing water resources and decreasing water shortages in agriculture, drinking water, and the environment sectors, and supply-side policies combined with demand-side policies like increasing irrigation efficiency and reducing the per capita consumption of water can have a greater effect on economic, social and environmental development. It was also found that domestic water needs were met in all months, but in the agricultural sector, only 20% of agricultural water was provided to farmers in the summer months. Therefore, based on field observations, the agricultural sector is facing more problems in supplying water to the regions. Finally, for environmental needs, 184,000 cubic meters of water needed by Hamon Hirmand has not been supplied.
       
  • Processing date kernels for iron (III) and chromium (VI) adsorption from
           water

    • Abstract: Inexpensive and new adsorbents, which are produced by processing the abundant agricultural by-products, can provide an efficient solution for a cleaner environment. The occurrence of heavy metals in water may pose a significant threat to human health. In this work, the processed date kernels are used to remove chromium (VI) and iron (III) from water. The XRD, FTIR, SEM, VSM and EDX techniques are used to characterize the adsorbents. The equilibrium adsorbent dose for iron is 2 g/L while for chromium (VI) it is 4 g/L and the equilibrium time is 20 min. Moreover, acidic conditions favored the adsorption for both targets. The adsorption experiments showed that the kinetics of adsorption of chromium (VI) and iron (III) on date kernel powder fitted the pseudo-second-order model. The optimum adsorption capacities for iron (III) and chromium (VI) are 10.5 mg/g and 0.66 mg/g, respectively. In the meantime, the remarkable efficiency of the date kernel-based adsorbent for iron (III) removal paves the way for designing new magnetic adsorbents.
       
  • The enhancement in dye removal and antifouling capability of PES
           nanofiltration membrane modified with fumarate-alumoxane nanoparticles

    • Abstract: Fumarate-alumoxane nanoparticles (Fum-ANPs) incorporated PES nanofiltration membrane was fabricated via phase inversion to achieve favorable performance as the enhancement in the dye removal and antifouling capacity. FTIR spectra of the Fum-ANPs revealed that the carboxylate and hydroxyl functional groups were created on the surface of Fum-ANPs. The strong affinity of Fum-ANPs functional groups with water molecules made the membrane surface more hydrophilic. Hence, the modified membrane sample had a higher pure water flux than the bare one. Zeta potential data showed that the Fum-ANPs blended PES membrane was negatively charged at a pH value of 6, which is favorable for negatively charged solute rejection. The antifouling behavior of the membranes was analyzed using powder milk solution (8 g/L) in a dead-end filtration system. The obtained results demonstrated that the introduction of Fum-ANPs in the membrane matrix ameliorated the antifouling behavior of the resulting membrane. To further study the performance of the Fum-ANPs incorporated PES membrane, removal of Direct red 16 dye was tested. The removal efficiency of Direct red 16 with the Fum-ANPs blended PES membrane was 99% while it was 88.2% for the bare membrane sample.
       
  • Electro-enhanced membrane separation technology for fouling mitigation in
           wastewater treatment: A review

    • Abstract: The research on membrane-based filtration technology for water treatment has expanded in recent years. Membrane fouling is a major challenge that decreases the permeability and decreases the lifetime and selectivity of the membrane. Recently, it was found that fouling mitigation and better control of membrane fouling can be attained under the application of the electric field. This paper provides an overview of the application of the electric field to the filtration process and its antifouling mechanism. Utilization of conductive polymeric membranes and application of electric field in membrane bioreactors are reviewed as well. The presented review demonstrates that the introduction of negative charge into the membrane surface via preparing conductive membranes or applying an external electric field onto the membrane surface suggests several advantages. These are fouling alleviation, better control of membrane fouling, an increase of membrane resistance to cake deposition on the membrane surface, and superior possible applications such as better salt rejection and antibacterial activity.
       
  • Improvement of COD removal and electricity generation in a MFC through
           embedding sulfonated reduced graphene oxide in a SPEEK proton exchange
           membrane

    • Abstract: Graphene oxide has attracted many interests in the recent decade due to its unique mechanical and chemical properties. This study focuses on the modification of graphene oxide and preparation proton exchange membrane (PEM) by sulfonated poly ether ether ketone (SPEEK) as base polymer for using in MFC as a modified membrane to remove COD and electricity generation. The scanning electron microscope (SEM) images, Fourier transform infrared (FTIR) and contact angle measurements were used to verify hydrophilic properties of the synthesized membranes. First, preparation procedures and properties of sulfonated reduced graphene oxide are briefly described. Subsequently, modification of proton exchange membrane from SPEEK polymer with prepared nano particle of sulfonated reduced graphene oxide 0.5 wt. % and its operation in MFC was considered. COD removal, power density, current density and coulombic efficiency were monitored during the process operation to evaluate the MFC performance. During the process operation, COD removal, power density, current density, and coulombic efficiency were tracked to assess the MFC performance. The power density and current density, 39.43 mW/m2 and 161 mA/m2 and the columbic efficiency 48.9 % was obtained, respectively. The COD removal of 89.5 % was obtained.
       
  • Aquifer vulnerability assessment in a semi-arid zone of Iran

    • Abstract: The importance of water shortage in arid and semi-arid regions is more evident due to the limitation of water resources, and the preparation of water resources is necessary to protect and reduce the vulnerability of these resources. Therefore, in this study, considering the vulnerability of water and soil resources in arid and semi-arid regions and the geographical structure of Zagros inland basins, the Izadkhast plain from the south of Fars province was selected to investigate the vulnerability of water resources. For this purpose, six parameters of water depth, net feed, aquifer environment, soil texture, topography, and hydraulic conductivity of the aquifer were analyzed using the DRASTIC model. The results showed that almost 50% of the plains were in the high vulnerability class, and 28% were in the very high vulnerability class. In the east and center of the plain, places with high vulnerability to pollutants and contaminated water were found. The effect of the formations in the east of the basin can be seen because, at the outlet of the rivers in the east of the basin, the amount of sulfate has increased dramatically, which indicates the presence of evaporate formations with gypsum. In the center of the basin, the heavy texture of the soil, the low slope, and the accumulation of most of the water entering the basin, some of which have a lot of salts, have increased the vulnerability of this part. Another result of this study is that the DRASTIC model has high efficiency in evaluating vulnerabilities similar to this research.
       
  • Investigation of integrated model for optimizing the performance of urban

    • Abstract: Due to the rapid population and economic growth, the demand for water has increased. In addition, the natural resources are limited and degrade because of several factors such as the climate change. These challenges lead to reduce the ability of providing water at the required quantity and quality. One of solutions to maintain the sustainability of water supply from different sources is reuse of wastewater. For this aim, it is crucial to optimize wastewater systems. This research paper aims to describe different modelling possibilities and optimization methods for various components of integrated urban wastewater systems. The main conclusion of this research paper is the lack of study of optimum design and operation of urban wastewater systems in a holistic method. Moreover, most of previous studies on integrated wastewater management have been conducted on combined sewer systems.
       
  • Comparison of head – leakage flow equations for circular holes in water
           distribution networks with a new equation

    • Abstract: In the operation of water distribution networks in cities, leakage from pipes always causes problems for human health and for the environment. Leakage openings in pipes may exist in different shapes. Circular holes are common in corroded and punched pipes. In the leakage studies, the area of these openings is usually assumed to be fixed and the leakage exponent is about 0.5. In this study, an analytical equation has been presented with two purposes. First, Examining the changes in the leak area and leakage exponent of circular holes. Second, providing an equation that contains more parameters than the general leakage equations. By using such an equation, the accuracy of leakage estimation is increased due to the direct involvement of the effective parameters. Also, for the possibility of modeling different leakage equations, including the present equation, a new hydraulic analysis model has been developed. This model tries to improve leakage modeling by including more capabilities than the existing hydraulic analysis models. Results showed that the leak area in circular holes is not fixed and changes due to different parameters. Comparison of the present equation and the orifice equation showed a significant difference which confirms that the orifice equation cannot be always used for circular leaks. In the study of leakage exponent, it was found that for polyethylene pipes, the leakage exponent is higher than value of 0.5 mentioned in the other studies and it can take different values depending on the leakage position in the network. Increasing the hole diameter did not affect the leakage exponent, but increased the leakage coefficient. On the other hand, for steel pipes, the leakage coefficient was fixed and the exponent remained around 0.5. Finally, the results showed the usefulness of the developed hydraulic analysis model for implementing the scenarios defined in this study.
       
  • Evaluation of the various adsorption isotherm models for the
           photocatalytic removal of methylene blue from the wastewater by graphene
           oxide/TiO2/SiO2

    • Abstract: Treatment of wastewater is a crucial step in reducing pollution from the textile and dyeing industries. One of the best techniques for dye removal is photocatalytic processes, and TiO2 is frequently employed in numerous wastewater treatment applications. In this study, different adsorption isotherm models and experimental data from the removal of the methylene blue dye from wastewater by applying GO/TiO2/SiO2 nanocomposite were compared. The correlation coefficient values (R2) for the Langmuir isotherm type 1 (Hanes-Woolf), Temkin, and Freundlich were determined to be, respectively, 0.9957, 0.9823, and 0.9515. Additionally, the R2 values for the Redlich-Peterson, Sips, and Toth isotherms models were 0.9575, 0.9626, and 0.9629, respectively. Therefore, Langmuir isotherm type 1 has the highest R2 and is the best model for surface adsorption of methylene blue on GO/TiO2/SiO2 photocatalyst. As a result, monolayer adsorption was most likely dominating during the adsorption. Furthermore, this photocatalyst proved suitable for lower methylene blue concentrations and systems with lower temperature sensitivity.
       
  • Update data of the Iranian wetlands (2023)

    • Abstract: Wetlands, as temporary or permanent water reservoirs, provide various benefits for the ecosystem, such as water supply, waste water treatment, and dust control. By the end of 2023, the Iranian government and the Ramsar Convention have registered 25 international and 226 national wetlands. West Azerbaijan and Mazandaran provinces have more wetland ecosystems than any other provinces. Semnan, Yazd, and Zanjan provinces have no wetlands. According to the Ramsar Convention of 1971, Iran has 32 aquatic ecosystems that have the potential to become wetland. In addition, according to the available data and the WHO standard, eight wetlands have the highest probability of producing dust and should be given more attention and care. We recommend the wetland management plan, which ensures their water requirements, protects them from degradation and pollution, and promotes their ecological restoration. Satellite image analysis can help explore how climate change affects dust intensity, considering the role of wetlands in dust control.
       
  • Adsorptive removal of dyes by utilizing activated carbon-supported copper
           derived from natural bitumen

    • Abstract: This study explored the efficacy of a cost-efficient activated carbon (AC) derived from natural bitumen through chemical activation with phosphoric acid. The objective was to evaluate bitumen-based activated carbon (AC) potential as a novel adsorbent by integrating Cu (NO3)2.3H2O onto AC for the removal of harmful dyes from water-based solutions. Assessments of the adsorption capabilities of Cu@AC were conducted using representative samples of cationic and anionic dyes, namely methylene blue (MB) and methyl orange (MO). The incorporation of Cu onto the AC, leading to the formation of Cu@AC, resulted in a significant enhancement of the adsorption capacity of AC. The adsorption capacity of Cu@AC was measured using Brunauer–Emmett–Teller (BET) and iodine number measurements, with the most optimal Cu@AC sample exhibiting a BET surface area of 611 m2/g. Surface chemical properties were analyzed through FT-IR spectroscopy, while the microstructure of the produced Cu@AC was examined using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The efficiency of the adsorption process was influenced by factors such as pH, initial dye concentration, adsorbent dosage, and contact time. The most effective processing conditions for dye removal were determined as pH 11 for MB and pH 5 for MO, with an initial concentration of 25 mg/L, a 0.5 g/L adsorbent dosage, and a temperature of 333 K for a duration of 90 min. Under these optimized conditions, removal efficiencies exceeded 90% for MO and 80% for MB. The results demonstrated that Cu@AC has the potential to function as a cost-effective alternative to commercially available activated carbons for efficiently eliminating dyes from contaminated water.
