Production Process of Poly Aluminum Chloride
1.Drum drying type:
Alum purity around 28%, water insoluble content high,most used in waste water treatment and
2.Spray drying type
1) golden yellow color:
Alum purity can reach to 29%-31%, water insoluble content low, dissolved fast, used in drinking water treatment
2) white color powder:
Alum purity can reach to 29%-31%, water insoluble content low, dissolved fast, used in drinking water treatment, also can be used in paper production to increase the paper's tension and whiteness
