Since the 1940s, Westlake Water Solutions has been manufacturing calcium hypochlorite. You could say we know as much about the product as anyone in the world. And ever since we produced our first pound of calcium hypochlorite, we’ve refined our chemistry, the forms in which we manufacturer it, the delivery systems used to provide cal-hypo and our areas of expertise. Westlake Water Solutions has a product to cover your individual needs — from backyard swimming pools to million-gallon water parks; from potable water to wastewater treatment; from vegetable washing to meat processing; from irrigation to bottling operations. We are also the pioneers of the only tableted water balancing system that is NSF 50-listed.
