  • Optimization of cyanide extraction from wastewater using emulsion liquid membrane system by response surface methodology

    To solve the disposal problem of cyanide wastewater, removal of cyanide from wastewater using a water-in-oil emulsion type of emulsion liquid membrane (ELM) was studied in this work. Specifically, the effects of surfactant Span-80, carrier trioctylamine (TOA), stripping agent NaOH solution and the emulsion-to-external-phase-volume ratio on removal of cyanide were investigated. Removal of total ...

  • Characterization and source identification of stormwater runoff in tropical urban catchments

    The characteristics of urban stormwater pollution in the tropics are still poorly understood. This issue is crucial to the tropical environment because its rainfall and runoff generation processes are so different from temperate regions. In this regard, a stormwater monitoring program was carried out at three urban catchments (e.g. residential, commercial and industrial) in the southern part of ...

  • Area-differentiated modelling of excess nutrient and contaminant leaching risks at the river-basin scale using a hydrological approach in India

    Application of excess nutrients, such as fertilizers, is a significant and sometimes even major component of groundwater pollution. Diffuse inputs of nutrients and contaminants to the groundwater are related to runoff generated from precipitation on a catchment. This implies that the analysis of diffuse fluxes from the land surface to the groundwater requires an analysis of water fluxes for a ...

  • State of well-water quality in Kakua Chiefdom, Sierra Leone

    Water is the difference between living and non-living and water for drinking should be pollutant free. Thus, in supplies for urban and rural consumption, water quality is one of the most critical parameters to verify. Well and/or open-water systems are easily liable to anthropogenic contaminations, the source of most water-borne epidemics especially in developing countries like Sierra Leone. ...

  • Nonpoint source of nutrients and herbicides associated with Sugarcane production and its impact on Louisiana coastal water quality

    A watershed analysis of nonpoint-source pollution associated with sugarcane (Saccharum officinarum L.) production was conducted. Runoff water samples following major rainfall events from two representative sugarcane fields (SC1 and SC2) were collected and analyzed. The impact of runoff on two receiving water bodies, St. James canal (SJC) and Bayou Chevreuil (BC) in a drainage basin (Baratarian ...
