Shandong TAIHE water treatment Co., Ltd. (former Zaozhuang TAIHE chemical factory) is located in Zaozhuang city, south of Shandong province.
The company was founded in 1998. It is one of the largest and professional water treatment chemicals factory in China, can manufacture all kinds of water treatment chemicals. The total yields reach to over 20,000 tons now.
The product families include antiscalant, corrosion inhibitors, biocide agents, cleaning agents, pretreatment filming agents, chelating agents, dispersants, RO membrane chemicals and etc., covering wide ranges from single to complex agents. The products are widely used in industrial circulating water system, boiler and heating water system.
To satisfy the need of different fields, some solid products such as organophosphoric acids and their sodium salts are developed recently in our factory, including high pure grade and ordinary grade. Some polymer solid products have also been developed.
To cooperate with our clients for water quality analysis and treatment process planning, we have set up a synthesis and application laboratory, several research projects are done in this laboratory.
