Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
Products Types
1. PAC S - white powder -spray dry
2. PAC H - bright yellow powder-spray dry
3. PAC V - light yellow powder -Spray dry
4. PAC R - yellow powder - roller dry
5. PAFC - dark yellow- roller dry
Application:
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.
