A Short Review on Arsenic Removal from Water
نویسنده
چکیده
Wastewater treatment is gaining importance because of increasing awareness about health effects of water pollutants and stringent norms of regulatory bodies. Removal of heavy metals from industrial effluent can be carried out by various methods like ion exchange, adsorption, activated sludge process, electro coagulation, membrane separation processes, precipitation, coagulation etc. Arsenic is one such heavy metal which contributes to heavy metal pollution. The research on arsenic removal includes studies on solute up take, kinetic and isotherm studies. The present review aims at summarizing the research carried out for removal of arsenic from wastewater.

متن کاملReview of Coagulation Technology for Removal of Arsenic: Case of Chile
Coagulation technology has been used since 1970 in northern Chile for removing arsenic from drinking-water. This experience suggests that coagulation is an effective technology for the removal of arsenic. It is currently possible to reduce arsenic from 400 microg/L to 10 microg/L at a rate of 500 L/sec, assuming pH, oxidizing and coagulation agents are strictly controlled. The Chilean experienc...
