Chemical plant sewage treatment, polyaluminum chloride can effectively remove the chemical oxygen demand in wastewater COD, which is recognized by the chemical
It is through flocculation, precipitation and thus achieve the purpose of water purification, the price is relatively polyacrylamide 8000-20000 yuan & # 47; and
If the treatment process for the post-chemical and physical, the dosage PAC about 0.1% (GB, 10% effective content), PAM about 1-3ppm, that is, for each 10,000 t
Poly aluminum chloride is Al2 (OH) nCl (6-n) It reacts with potassium fluoride Al2 (OH) nCl (6-n) + 6KF = 2AlF3 + (6-n) KCl + Sex
High-purity white more expensive, more about 17,000 anions more normal. Polyaluminium chloride PAC mainly depends on your use of occasions, the price of drinkin
