Aluminum Chloride Hydroxide
Al(OH)aClb, (a+b)=3
Product Overview
ATCO ACH coagulant types are new generation coagulant groups which have high basicity and high removal capacity of turbidity, color, suspended solid matters, organic carbons, and heavy metals. ATCO ACH coagulant types can be produced as including active matters from 5% up to 23% Al₂O₃ according to customer demands. ACH is also widely used in swimming pool applications and in the cosmetics industry as an antiperspirant.
