Pilot-Scale Study on Treatment of High-Algae and Low-Turbidity Source Water by Air Flotation in South China

Abstract:

Article Preview

The pilot-scale experiment of air flotation was carried out for reservoir water treatment of Shenzhen in order to provide reference for waterplant. The results show the turbidity of raw water is higher or lower than 15NTU, the optimum dosage of poly aluminum chloride (PAC) is 1.65mg/L and 1.25mg/L respectively. When the turbidity of raw water is between 3NTU and 32NTU, the amount of algae is less than 1.08×107unit/L, the removal rate of air flotation for turbidity and algae is 89.3% and 92.7% respectively; besides, the average removal rate of air flotation on CODMn is 32.6%, 21.2% of TOC is removed at least. Air flotation has preferable treatment effect on high–algae and low-turbidity water, adapts to treat micro-polluted water in South China.
