Yixing Cleanwater Chemicals Co., Ltd.

China’s Jiangsu province, in the Yixing area, hosts Yixing Cleanwater Chemicals Co., Ltd. with a catalogue of 15 active chemical products. The company lists items that fall under water treatment, agricultural and general industrial chemistry, covering both inorganic coagulants and organic polymers. Products include Poly Aluminum Chloride (PAC) variants, several grades of polyacrylamide such as cationic APAM, and bacterial agents for bio‑remediation. The catalogue also contains deodorising agents and specialty chemicals like PDADMAC, each identified by their trade names rather than HS codes. The listing reflects a focus on chemicals used in flocculation, coagulation, sludge treatment and water de‑colouring processes.

The product list comprises Poly Aluminum Chloride, PAC‑02, PAC‑05, PAC‑09 and a generic “PolyAluminium Chloride pac”, as well as Polyacrylamide, Cationic polyacrylamide (APAM) and PDADMAC, which are typical high‑molecular‑weight polymers. Biological solutions include a general Bacteria Agent, an Anaerobic Bacteria Agent and a Deodorising Agent, all aimed at enhancing biological treatment stages. Water decolouring agents are presented under the CW‑08 and CW‑05 names. Each entry corresponds to a distinct formulation used in municipal or industrial water‑treatment plants, agricultural irrigation systems or industrial process streams.

The catalogue centers on water‑treatment chemicals: inorganic coagulants such as Poly Aluminum Chloride (PAC) in several grades, organic flocculants like anionic and cationic polyacrylamide (PAM, APAM) and cationic polymers such as PDADMAC. In the industry, PAC is typically offered at Al₂O₃ contents of 30 % - 45 % and specified by residual aluminum concentration, while polyacrylamide grades are distinguished by molecular weight (0.5 - 10 million g mol⁻¹) and charge density (0.5 % - 10 %). Bacterial agents are usually supplied as freeze‑dried cultures with viable counts expressed in CFU g⁻¹, and deodorising agents are formulated for odor control in wastewater treatment. The CW‑08 and CW‑05 decolouring agents are organic oxidisers commonly graded by COD removal efficiency (e.g., >80 % in laboratory trials).
