      Experiments were conducted using sodium alginate (SA) and polyvinyl alcohol (PVA) as embedded materials for Fe3O4 magnetic nanoparticles (MNPs). The materials provided excellent protection to the embedded MNPs in low-pH conditions. This study observed and compared the adsorption capacity of the unaltered and embedded MNPs. At pH 3 and without additional magnetic fields, the wastewater turbidity removal rate of the embedded MNPs reached a maximum of 95%, similar to that of the unaltered MNPs. Moreover, this study examined the recyclability and reusability of the unaltered and embedded MNPs and discovered that the embedded MNPs could be reused up to seven times. Overall, the use of SA/PVA prevented MNPs from disintegrating and contaminating the wastewater through the dissolution of Fe ions. SA and PVA also increased the reusability of the unaltered MNPs.

  • Hydrogeochemical characteristics and groundwater contamination in the
           rapid urban development areas of Coimbatore, India

      The Singanallur Sub-basin is one of the major waterways and it supplies water to the Coimbatore city. Currently, it is vulnerable to pollution due to an increase of unplanned urban developments, industrial, and agricultural activities that compromise both the quality and quantity. In the present study three major hydrochemical facies were identified (mixed Ca-Mg-Cl, Ca-Cl, and Ca-HCO3). Irrigation suitability indexes are specifies that the groundwater in the areas has very high salinity hazard and low to medium alkali hazard. The mechanism controlling groundwater chemistry originally regulated by the evaporation process is dominated by reason of arid condition and anthropogenic activities existing throughout the region. The multivariate statistical analysis (Correlation analysis (CA), principal component analysis (PCA) and Hierarchical cluster analysis (HCA)) indicates, most of the variations are elucidated by the anthropogenic pollutant predominantly due to population growth, industrial effluents, and irrigation water return flow. This study demonstrates enhanced information of evolution of groundwater quality by integrating hydrochemical data and multivariate statistical methods are used to understand the factors influencing contamination due to natural and anthropogenic impacts.

  • Exploratory analysis of fines for water pollution in Bangladesh

    • Authors: Nabil Haque
      Abstract: Publication date: December 2017

      As a consequence of rapid industrialization, the waterbodies of Bangladesh have transformed into seasonal dead zones from the ensuing pollution. Despite having environmental regulations to control industrial pollution, lack of effective enforcement has jeopardized environmental quality. Evaluation of enforcement mechanisms have not gained attention from researchers until recently. This qualitative and descriptive analysis illustrates the current enforcement regime for environmental compliance in Bangladesh focusing on fines levied on polluters. Although there are no official guidelines for fines based on type of violation, this paper identified that there are differences of fines among violation based on historical data. It was also found that textile factories are not penalized heavily compared to non-textile factories. Repeat offenders were found to be penalized at the same rate. This study can be used to design appropriate penalty structure based on violation types, and reform the enforcement system so that polluters pay principle is actually implemented.

  • CARBON AND ENERGY FOOTPRINT ANALYSIS OF TANNERY WASTEWATER TREATMENT: A
           GLOBAL OVERVIEW

      In this study the carbon footprint and power demand of tannery wastewater treatment processes for the largest bovine leather producing regions were quantified and analysed. Moreover, we present a case in which we benchmarked the carbon footprint and energy demand analysis of tannery wastewater treatment to municipal wastewater treatment. We quantified the greenhouse gas direct and indirect emissions from tannery wastewater treatment facilities. Our results show that the total CO2-equivalent emission for tannery wastewater treatment is 1.49 103 tCO2,eqd−1. Moreover, the energy intensity of tannery wastewater treatment processes are evaluated at 3.9 kWh kg−1bCOD,removed, compared to 1.4 kWh kg−1bCOD,removed of municipal wastewater treatment processes. Based on this work in the field of tannery wastewater treatment, an effort to innovate suitable treatment trains and technologies has the strong potential to reduce the carbon footprint.

  • A corporate water footprint case study: the production of Gazpacho, a
           chilled vegetable soup

      This paper analyses the water footprint (WF) for 1L of gazpacho, a chilled vegetable soup produced by an agrifood company located in south-eastern Spain, one of the driest regions in Europe. An overview of the main environmental impacts of its WF was carried out by identifying hotspots (high risks areas) based on a Water Stress indicator. The total WF calculated for 1L gazpacho is 580.5L, which mostly stems from the supply chain (99.9%), olive oil being the major contributor to total WF despite the very low amount used (2%). Most of the WF comes from green water (69%), 23% from blue and 8% represents the grey water. Pollution due to micropollutants such as pesticides, which are not yet regulated, has been taken into account in the WF calculation, pointing out that new regulation of micropollutants is needed to avoid their exclusion in the operational grey WF.
