Powdered Poly Aluminum Chloride Image Added

Powdered poly aluminum chloride is being used in Guatemala at one of their hydraulic water treatment plants (El Cambray). This provides a new opportunity for a way to treat water with low alkalinity. Apparently the costs are comparable to alum because you use less of the product, but it costs more per kg.
