Yang Hang company factory was built in the early 1980s, which is one of the earliest professional manufacturers engaged in water treatment materials in China. The company has an annual output of 150000 tons of water purification agent products. Our products include Polyacrylamide Flocculant series: anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM), Nonionic polyacrylamide (NPAM), salt resistant and high temperature resistant polyacrylamide for oil field, instant polyacrylamide, etc.,in which instant polyacrylamide can be directly added without dissolving, with fast flocculation speed, large floc, small dosage and good effect. Powder polyaluminium chloride (28% - 30% of Al2O3) and granular polyaluminium chloride (24% - 30% of Al2O3) can satisfy the purification of industrial water and drinking water. Active carbon series products, shell active carbon, coconut shell active carbon, column active carbon. Solid sodium acetate / sodium acetate, liquid sodium acetate / sodium acetate; alumina ball: activated alumina ball, potassium permanganate alumina ball, etc. The products are widely used in water supply, drainage, power, steel, chemical industry, oil field, papermaking, medicine, food and many other fields of water treatment.
