Dissolve the solid product into liquid in 1:3 with water, and then dilute it with 10-30 times of water to the required concentration. The best pH value for the addition is 3.5-5.0. The best pH value can bring the maximum benefit of coagulation. The dosage can be determined according to the different turbidity of raw water, Generally, when the turbidity of raw water is 100-500mg/L, the dosage per thousand tons is 10-20kg.. When the turbidity of the raw water is high, the dosage is appropriately increased, and when the turbidity is low, the dosage can be appropriately reduced.
For rural use, the medicine can be put into the water tank, stirred evenly, static, supernatant can be used, every 50 kg to add about l grams of this drug. If the agent is used in combination with a polymer flocculant produced by the company, the effect is better. The drug can be used to dissolve the anionic polyacrylamide or cationic polyacrylamide together with PAC into a composite flocculant or to add PAC to the treated water to form agglomerates, and then add the anionic polyacrylamide produced by the company to form a large flocculant for adsorption
