The concentration of polyaluminum chloride determines the quality of the purification effect. Polyaluminum chloride PAC is produced by the bridging effect of hydroxide ions and the polymerization of polyvalent anions. It has high efficiency, large molecular weight, high charge, less impurities, high molecular weight, and good coagulation effect. Large block, high activity, rapid sedimentation and separation.
Polyethyl chloride is mainly used for sewage or drinking water treatment. It is higher than other aluminum salt and iron salt. It has a small erosion effect on equipment. It can remove turbidity, dehumidification, oil removal, dehuminating, iron removal, iron, chromium, phenols, phenol, etc. The removal of radioactive pollution substances and organic pigments in water can achieve ideal results. Sewage, water treatment of purification industries, power generation, steel, papermaking, printing and dyeing, leather, chemical industry, coal washing, mineral selection, metallurgy and other industrial waste sewage treatment.
It is recommended that when you purchase or use high-quality polyaluminum chloride, you must first understand its cost-effectiveness, understand the water quality you are treating, and subdivide the sewage produced by the plant, whether the sewage treatment process is air flotation process or other processes, and there is no poorly treated water quality. Only when you fully understand the water quality can you choose suitable water purifier products.
The dissolution ratio of polyaluminum is 5%, that is, 50g of flocculant A is added to 1kg of water for dissolution. (Water for dissolving chemicals is tap water or pure water), the stirring and dissolving time is 5-10min, and the standing dissolving time is 0.8-1h. The specific dosage is determined according to the concentration of sewage and treatment standards.
Due to the different quality of polyaluminum chloride produced by different manufacturers, when using polyaluminum chloride PAC, users should remember to do a small test before use, especially in winter and summer, temperature and humidity have a great influence on the concentration configuration of polyaluminum chloride, and a reasonable configuration before the test is needed
