BIOSIS COPYRIGHT: BIOL ABS. In a laboratory lime softening test, maximum removal of arsenic from a groundwater (total arsenic 0.68-0.70 mg/l; arsenic (III) 0.59-0.60 mg/l) was 90% (residual arsenic 0.07 mg/l) at a lime dose of 1250 mg/l (pH 11.8). With powdered bituminous coal additive (2 g/l), residual arsenic level below the WHO guideline value (0.05 mg/l) was achieved at a lime dose of 800 mg/l (pH 11.5). The magnesium-hydroxide precipitate played a more significant role in removing arsenic, particularly As3+.
