Methodology: | The fine fractions of GEH and other adsorbents are used for arsenic removal from drinking water in adsorption-membrane hybrid system at various operation conditions. In hybrid system the entire treatment activity (such as adsorption, liquid-solid separation, and sludge accumulation and withdrawal) will be carried out in a single unit. The results will be compared with known transport models (homogeneous surface diffusion model) and, if necessary, model adjustments will be carried out. Model predictions will be based on adsorption equilibrium and kinetic parameters determined from isotherm and batch experiments, respectively.
