PAC is made up of multicomponent hydroxy complex.It has high rapidity of flocculation and deposition ,and been applied to the wide breadth PH value scope.It has no causticity to the pipe equipments,obvious effect of cleaning water and wiping off SS,COD,BOD ,and some heavy metal ions such as As ,Hg...ect in water.This pruduct is applied to the drinking water,industry water and dirty water disposing fields.
