| General Product Information |
| PAC is used in water treatment for removal of Suspended solids (turbidity) and other contaminations such as natural organic matter from surface water, Micro- organisms and colloidal particles, silt and clay are stabilized by surface electrostatatic charges preventing the particles from coalescing .It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum. |
| Applications |
| Paper Manufacture: With filler, pigment effluents |
| Textile Industry: Elimination of dyes |
| Refineries: Containing oil waste water |
| Ceramic Industry: Colloidal Pollutants |
| Automotive Industry: Effluents with detergents, soil & paint residues |
| Laundries: Detergents, soil |
| Car Wash Installaries: Waste water with oil, and grease |
| Food Processing Industries: Effluents containing fats and vegetable oil. |
| Handling |
| It is not a hazardous chemical but moderately acidic in nature. Plenty of water can be used if spillage occurs on hands, face or any other part of body. |
