Poly Aluminum Chloride

GK FINECHEM CO., LTD.’s Poly Aluminium Chloride (PAC) was the first to be introduced and manufactured in Thailand at GOSHU KASEI CO., LTD., a GOSHU KOHSAN group company, under the license of ASAHI CHEMICAL CO., LTD., the subsidiary company of SUMITOMO CHEMICAL CO., LTD. in 1992 and we maintain top market share in the country.
PAC is a coagulant characterized by its low impurity content, high coagulation ability, stable physical properties and durability, so that it can be used for purification of water, such as City Water, Industrial Water, Industrial Waste Water and Civil Waste Water and intermediates for pharmaceuticals. The quality system for manufacturing of PAC was certified for ISO9002 Certification by RWTUV in 2000.
