Paper Title:
Effect Factors of Air Flotation Treating Micropolluted Source Water in South China
  Abstract

The Southern source water carries such characteristics as high algae, low turbidity and micro-polluted. In order to make flotation better applied to the source water, the following factors are researched to find out the influence on the flotation from type and dosage of coagulant, dissol- ved air pressure, air inflow. Aluminum sulphate, ferric chloride, poly aluminum chloride (PAC) are selected. With less PAC, scum generated less, the coagulant dose is 1.25mg/L.Dissolved gas pressure is directly related to bubble size.When the pressure is greater than 0.42Mpa,the effluent quality deteriorates as the pressure increases.The volume of inflow gas into the raw water is related to turbidity and capacity.The higher the turbidity of the water is, the greater the capacity will be, so the higher feed rate can be chosen.
