Sewage-grade polyaluminum chloride is an inorganic polymer flocculant , which is a high-molecular-weight , high-charged inorganic polymer water treatment agent due to the bridging action of hydroxide ions and the polymerization of polyvalent anions. The molecular formula is [AL2(OH)nCL6-n]m (n is 1-5 m<=10). Base degree: B = n / 6 × 100%.
Its coagulation effect is as follows: 1. Strong electrical neutralization of colloidal substances in water. 2. Excellent bridging adsorption of hydrolysate on suspended solids in water. 3. Selective adsorption of dissolved substances.
Application method and notes:
1 .The product shall be diluted with 10-40 times water, then added to the wastewater directly. After stirring for several minutes, the clear water will be got by precipitation or air-floatation.
2. The optimized pH of the wastewater accepted is 6-10.
3. It is recommended to use this product with the inorganic flocculants to treat the effluent with high color and COD to reduce the operation cost. The order and proportion of agent dosage depend on the flocculation test and the effluent treatment process.
4. The product would show layer separation and become white at low temperature. There is no negative impact on the usage after mixing up.
