Ming Rui water and sewage treatment plant after repeated use of the experiment, when the raw water turbidity increased, its dosage is increased by less than ferric chloride, the higher the turbidity, the difference was more significant. Such as aluminum sulfate and compare, at the time of any turbidity, PAFC dosing were less than aluminum sulfate dosage. Yushchenko PAFC can be applied to the disposal of the Yellow River high turbidity of the water. Within a certain range, the turbidity of the raw water, the greater the range of turbidity change, its advantages more apparent. First, the PAFC flocculant solid product is brown, reddish-brown powder, easily soluble in water. The amount is much lower than traditional coagulants, purified water quality is excellent. Second, the floc constitute fast, agile precipitation disposal to larger than conventional products, hydrolysis speed, water, weak collaboration. Consisting of alum dense settlement rate. By the temperature change is small, can occur in the active process of contentment shear requirements. Third, the PAFC less medication, good disposition results than other coagulant cost savings of 10-20%. And consume less water alkalinity, water PH value decreased less. Four, PH value of the limitations of the combination of wide, in the 5.0-9.0 limitations may apply, the limitations of the available wide PAFC, drinking water, industrial water, domestic water, sewage and industrial effluent disposal.
