Arsenic Removal Technologies from Ground Water: Techno-economic Evaluation Madhuri Damaraju

Ground water is one of the main sources of drinking water especially in rural areas of India. Groundwater is generally regarded as safe to drink. At the same time ground water is rich with various minerals based on the minerals available in that particular Aquifer. Presence of these minerals beyond prescribed levels is harmful for human consumption. Some of them are Arsenic, Iron, Fluoride, Nitrates, salinity etc. Arsenic contamination of groundwater is a natural occurring high concentration of arsenic in deeper levels of groundwater, which became a high-profile problem in recent years due to the use of deep tube wells for water supply, causing serious arsenic poisoning to large numbers of people. Arsenic is treated by some methods like adsorption, precipitation, ion exchange, coagulation, filtration etc The objective of this work is to propose a techno-economic feasible water technology for removal of arsenic from Ground water.
