Description
Poly Aluminum Chloride is used for drinking water treatment (PAC-V) is a new type inorganic polymer coagulant with high efficiency. This product is made from aluminum hydroxide, hydrochloric acid and calcium aluminate powder employing advanced technology.
PAC-V owns high flocculation efficiency with lower cost. Its water purification capacity is higher than other traditional inorganic coagulants such as aluminum sulfate and other ferric salts. The solid product is produced employing the spray drying technology and the obtained product is primrose yellow, yellow or brown powder. Corresponding liquid products can also be provided.
Industrial applications
Pulp and paper
PAC is used to treat process water and effluents during paper making.
