Properties: Through the pressure produced by the spray drying process of porous granules of aluminum chloride or hollow small particles, dust and showing smoothness. Due to better contact with the water to be treated, its wettability and water velocity is stronger than other powder products.

 

Molecular Formula:   [AL2(OH)LnCL6-n]m

 

Use:  Drinking water treatment, industrial wastewater and municipal wastewater treatment.
