Arsenic removal from drinking water is a major problem in many parts of the world. We have investigated arsenic removal by flocculation and microfiltration. Ferric chloride and ferric sulphate have been used as flocculants. The use of small amounts of cationic polymeric flocculants, as flocculation

A computational model has been developed for the simulation and optimization of the pervaporation process. This model involves solving coupled mass and energy balances, and chemical potential equations using a genetic algorithm. A visual, windows-based, user-friendly design software has been develop
