Experiment Study on the Treatment of Arsenic Drinking Water in Integrated Efficient-Whirling Clarifier

Abstract:

In order to investigate arsenic drinking water treatment effect of enhanced coagulation in integrated efficient-whirling clarifier, and explore optimum working condition, the experiment of arsenic removal was carried out for raw water, the arsenic concentration of 0.1mg/L (100µg/L) and the turbidity of 100NTU. In this experiment, the oxidant’s dosage of sodium hypochlorite (NaClO) was 10mg/L and the coagulant’s dosage of ferric chloride (FeCl3) was 15mg/L, when three kinds of reaction time (T) in the first and second flocculation zone were employed, which respectively equal to 5.4 minutes, 2.7 minutes and 1.8 minutes. The results of experiment showed that the concentration of arsenic all drop below 10µg/L, which reached drinking water sanitary standard (GB 5749-2006), and the best working condition for arsenic removal was reaction time equal to 2.7 minutes.
