Polyaluminum chloride: The effect of low temperature turbid water treatment is general, and the effect of flocculation on the pH value is greater.
Polyaluminum ferric chloride: It has a strong adsorption capacity to water, so that colloidal impurities in water can be condensed;
    The addition amount is generally between 20 and 50 mg/L, and the pH is controlled at 6 during the flocculation process. The result of 5-7 is better, the water temperature has little effect on the flocculation effect, and the amount of alum is large, and the formation speed is fast.
