What is Poly Aluminum Chloride?
Poly Aluminum Chloride (PAC) is an inorganic polymer coagulant used primarily for water and wastewater treatment. It is composed of aluminum ions and hydroxide ions in a polymerized form, offering strong coagulation efficiency, fast settling, and low sludge production. PAC is available in both liquid and powder forms, making it versatile for different applications.
Common Applications
- Water Treatment: Used in municipal and industrial facilities for clarifying drinking water and treating wastewater.
- Paper Industry: Enhances retention and improves drainage during paper production.
- Textile Processing: Applied in dyeing and finishing processes to control pH and reduce color in effluent.
- Oil & Gas Industry: Acts as a clarifying agent for oily wastewater and drilling fluids.
- Food Industry: Utilized in water purification systems for food processing plants.
- Mining: Assists in separating suspended solids during mineral extraction.
- Cosmetics & Pharmaceuticals: Used in specific formulations for purification and pH regulation.
