Poly aluminium ferrous chloride is short for PAFC,It is brown, reddish-brown, dark yellow powder, easily soluble in water which plays an important role in drinking water, industrial water, domestic water, domestic sewage and industrial effluent treatment. Especially, it has more obvious effect on the high turbidity water and low turbidity water.
Chemical formula: [Al2(OH)nCl6-n]m.[Fe2(OH)nCl6-n], n≤5,m≤10.
China standard: GB15892-2003,
Chemical formula: [Al2(OH)nCl6-n]m.[Fe2(OH)nCl6-n], n≤5,m≤10.
China standard: GB15892-2003,
Using method:
