PAC is a kind of inorganic macromolecule flocculant. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule. It adapts a wide PH range of 5.0~9.0, and the best is between 6.5~7.6.
- Appearance: Typically available as a yellow, white, or red-brown powder, or as a clear to yellowish liquid.
- Formula: Often expressed as (Al_n(OH)_mCl_{(3n-m)}), where (n) indicates the degree of basicity.
- High Efficiency: PAC forms large, dense flocs, allowing for faster precipitation and lower dosing compared to traditional coagulants.
- Wide Application: Effective in drinking water purification, industrial waste treatment, and as a raw material in cosmetics (like antiperspirants).
- Safety: While effective, handling requires caution as it can cause skin and eye irritation
Primary Applications
- Potable Water Treatment: Purifying drinking water for municipalities.
- Wastewater Treatment: Removing suspended solids, COD, and BOD from industrial and municipal sewage.
- Industrial Processes: Used in papermaking, textile sizing, and as a pharmaceutical additive
