Characteristic and application

Polysilicate Aluminum FerricPSAF is improved from the traditional polyaluminum ferric chloride products. With polysilicate added, curing morphology of Al () and Fe () Hydrolysis - polymerization – sediment is more reasonable, with number of hydroxyl increasing, the degree of polymerization is greater, the molecular weight is increased, and the amount of polyaluminum in Al13 is more, which means the product is more effective. Therefore, PSAF is far more better than PAFC. In the drinking water treatment, the dosage is lower than PFS, PAC and other traditional products for turbidity removal, algae killing, decolorization and rapid sedimentation. With lower cost and high efficiency, PSAF is an excellent water purifying product.
