Composite PAFC Purifying
Ferric chloride (PAFC) is made of aluminum and iron salts coagulation hydrolysis of an inorganic polymer coagulant, based on the principle of synergy, added elemental iron or ferric oxide and other iron-containing compounds compound in the system A new and efficient coagulant obtained. It combines the respective advantages of aluminum and iron salts, aluminum ions and iron ions form has improved significantly, much higher degree of polymerization. Take aluminum, iron coagulant their flotation on Operating advantageous to improve the performance of PAC coagulation; high turbidity water and low temperature and low turbidity water purification treatment effect was particularly evident, do not add alkaline additives or other coagulant.
PAFC performance and benefits mainly as follows:
1, hydrolysis speed, hydration weak. Alum formed dense, fast settling velocity. By temperature change is small, meet the shear forces in the flow process requirements.
2, the solid product is brown, reddish-brown powder, easily soluble in water.
3, can effectively remove the source of aluminum ions in water and aluminum coagulation of water after the remnants of the free state aluminum ions.
4, wide application, drinking water, industrial water, domestic water, sewage and industrial wastewater treatment.
5, less medication, the treatment effect is good, than the other coagulant cost savings of 10-20%
