PAC

Appearance: yellow or red and yellow, showed mixed solid powder and small pieces. Properties: Molecular formula [AL2 (OH) nCL6-n] m (nno more than5, m no more than 10), is a type of inorganic polymer flocculants. Features: For a variety of source water turbidity, PH wide application and alum to form large, fast, fast settling velocity, corrosive small, low labor intensity. Is mainly used for drinking water treatment; industrial wastewater and urban sewage treatment; industrial wastewater and urban sewage treatment; and toxic heavy metals and fluorine-containing wastewater treatment. Usage: add water, stirring the solid dissolved, dubbed 5-10percent water (by weight), with water to join the source water, source water turbidity due to different, one ton of PAC can handle 1-10 million tons of source water. According to the different source water turbidity, in different regions, different seasons, different-shaped pools, testing, to find the best dosage. (Solid damp, there is no submission of debris and may also be used.)
