摘要 使用明矾和氯化铁等金属混凝剂处理水长期以来被认为是去除砷的有效方法。 NEERI 对从西孟加拉邦受砷影响的六个水源采集的水样进行了混凝-絮凝研究，以了解砷的去除情况。对这些水样的物理化学特性进行了研究。广泛的可处理性研究表明，剂量为 3.0 mg/L 的氯（用于预氯化），随后添加 50 mg/L 的氯化铁能够去除原水中的砷。讨论了除砷的结果。
Abstract 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.
