Water treatment: how to add flocculant polyacrylamide, polymeric ferric sulfate and polymeric aluminum sulfate?

The flocculation suit used by our company is called FK-FLOCK, which is produced by Wuzhou Fuji Chemical Water, and the effect is very good. Our waste liquid mainly contains copper 1000 ppm, and there are many other heavy metals with high content. Ferrous sulfate and aluminum sulfate are the main coagulant AIDS, and we use vulcanization to remove more than 65,438+000 ppm of heavy metals. The treatment rate can reach 99.8%. Our aluminum sulfate is 1 ton of water, 100 kg of medicine, and ferrous sulfate is the same as above. The dose of FK chicken is very small, but it is expensive, and it costs 8000 yuan for 20 kilograms. I don't know if this answer is good, hehe.
