M. Tech. Chemical and Metallurgical Engineering / Focuses on developing a reproducible, regenerable, effective and affordable adsorbent for the removal of fluoride, phosphorus and arsenic from water. The adsorption media should perform at room or low temperatures. To perform basic mathematical modelling to aid in adsorber design. The specific objectives are as follows: to apply a simple thermo-chemical process to convert limestone into a robust adsorption media ; to pelletize thermo-chemically converted limestone using organic binders ; to determine the effect of binders on arsenic, fluoride and phosphate removal from water and to apply basic models to interpret breakthrough results.
