摘要：

Water treatment with metal coagulants like alum and ferric chloride has long been recognised as an effective method for removal of arsenic. NEERI conducted coagulation - flocculation studies on arsenic removal on water samples collected from six sources in West Bengal which are affected by arsenic. The physico-chemical characteristics of these water samples were investigated. Extensive treatability studies have shown that a dose of 3.0 mg/L of chlorine (for pre-chlorination) followed by 50 mg/L of ferric chloride was able to remove arsenic from the raw waters. Results of arsenic removal are discussed.
