We are providing poly aluminum chloride in liquid form of an assurance of 99% purity. It is used in swimming pool water to remove various types of impurities. Such water often contains a large number of microscopic particles with the same negative chemical charge. As a result, they reject each other and do not readily settle down. The elimination of these contaminants is aided by poly aluminum chloride (liquid form) by bringing them out in the form of floc. This method is significantly faster than traditional methods. Hence, the impurities can easily be collected in a filter.
