Characteristic PAC Fe (PAFC) is made of aluminum and ferric salt coagulation an inorganic polymer coagulant hydrolysis, according to principles of synergy, joined the three single-quality iron or compound of iron oxide and other iron-containing compounds while the system was a new and efficient coagulant. It combines the respective advantages of aluminum and iron salts, aluminum ions and iron ions on the morphology are significantly improved, and greatly enhanced the aggregation. Take aluminum and iron coagulants their operations to the advantages of the flotation to improve the coagulation performance of PAC; for high turbidity water and low temperature and low turbidity water purification treatment effect was particularly evident, from time of alkaline additives or Other coagulant aid. PAFC performance and benefits mainly as follows: 1, the hydrolysis speed, hydration weak. The formation of alum dense settlement rate. Water temperature change by a small, meet in the shear force generated in the process flow requirements. 2, solid product is brown, reddish-brown powder, easily soluble in water. 3, can effectively remove the source of the water after the coagulation of aluminum ions and aluminum salts of free ions in water residual aluminum ions. 4, applies to a wide range of drinking water, industrial water, domestic water, domestic sewage and industrial wastewater treatment. 5, less medication, good effect, 10-20% savings over other coagulant cost. 6, using the methods and packaging uses, and notes with essentially the same PAC. PAC iron use First, according to different conditions of raw water before use to do first small scale, find the best delivery capacity. Second, production by: Solid: Water = 1 / 5, the first mixed solution, together with the water content was diluted to 2 to 3% of the solution can be.
