An Overview of Arsenic Removal Technologies in Bangladesh and India
In the context of prevalence of high concentrations of arsenic in tubewell water, a wide range technologies has been tried for the removal of arsenic from drinking water. The most common technologies utilized the conventional processes of oxidation, co-precipitation and adsorption onto coagulated flocs, adsorption onto sorptive media, ion exchange and membrane techniques for arsenic removal. Th...
متن کاملArsenic removal by coagulation
he current 50-μg/L maximum contaminant level (MCL) for arsenic in drinking water was first set by the US Public Health Service in 1942 and was adopted by the US Environmental Protection Agency (USEPA) in 1975.1 The standard was based primarily on toxic effects resulting from short-term or acute exposure to arsenic.2 Subsequent investigations have linked arsenic in drinking water with skin cance...
متن کاملArsenic Removal by Liquid Membranes
Water contamination with harmful arsenic compounds represents one of the most serious calamities of the last two centuries. Natural occurrence of the toxic metal has been revealed recently for 21 countries worldwide; the risk of arsenic intoxication is particularly high in Bangladesh and India but recently also Europe is facing similar problem. Liquid membranes (LMs) look like a promising alter...
متن کاملmanganese removal from aqueous solution by natural and sodium-modified zeolite
the purpose of this study is comparison of manganese absorption capacity by natural and modified zeolite. for this purpose used by from semnan mines zeolite with mean particle diameter of 360 micrometer. for modified zeolite, 5 g amount of natural zeolite with 100 ml of 1 m sodium chloride solution mixed and maintained at 24 hours in room temperature. for measure specific surface of absorbents,...
متن کاملRemoval of arsenic from water by electrocoagulation.
In the present study electrocoagulation (EC) has been evaluated as a treatment technology for arsenite [As(III)] and arsenate [As(V)] removal from water. Laboratory scale experiments were conducted with three electrode materials namely, iron, aluminum and titanium to assess their efficiency. Arsenic removal obtained was highest with iron electrodes. EC was able to bring down aqueous phase arsen...
