Poly Aluminum Chloride (PAC) is a water treatment chemical used for water clarification and purification. It works by neutralizing negatively charged particles in water, causing them to coagulate and settle out. PAC is widely used in municipal water treatment plants, industrial wastewater treatment, and swimming pool water treatment.
Type:
- Inorganic polymer: Poly Aluminum Chloride (PAC) is a type of inorganic polymer coagulant.
Material:
- Aluminum-based: It is primarily composed of aluminum, chlorine, and oxygen.
Usage:
- Water Treatment: PAC is widely used in water treatment processes, including:
Drinking water purification: Removes suspended solids, turbidity, and some organic matter.
Wastewater treatment: Treats industrial and municipal wastewater to remove pollutants.
Swimming pool water treatment: Helps clarify the water. - Other Applications:
Papermaking: Used in paper production processes.
Textile dyeing: Aids in the dyeing process.
How to Use:
- Dosage: The specific dosage of PAC varies depending on the water quality, desired treatment goals, and other factors. It’s crucial to conduct jar tests to determine the optimal dosage.
- Application:
- Solution Preparation: PAC is typically diluted with water to form a solution before application.
- Addition: The PAC solution is added to the water to be treated, usually at a specific point in the treatment process.
- Mixing: The water is then mixed to ensure proper distribution of the PAC.
- Flocculation: PAC helps form larger particles (flocs) that can be easily removed through sedimentation or filtration.
