Henan Hengju Chemical Co., Ltd.
About
Henan Hengju Chemical Co., Ltd. is a water treatment chemical manufacturer and subsidiary of Beijing Hengju Group, established in 1989 and operating from Lankao County, Henan Province, China. The company is one of the largest polyacrylamide producers in Asia, leveraging microbiological technology to produce high-quality crystal acrylamide that enables ultra-high molecular weight polymer manufacturing. Their core product line, marketed under the HENGFLOC brand, spans cationic, anionic, non-ionic, and amphoteric polyacrylamide formulations across ultra-high, high, medium, and low molecular weight grades tailored for sedimentation, centrifugation, and filtration applications in municipal and industrial water treatment. Specific products include HENGFLOC 70010 (non-ionic ultra-high MW for acidic-condition mineral processing), HENGFLOC 62424 and 62414 (anionic flocculants for mining), and HENGFLOC 62718 (general polyacrylamide). Hengju also manufactures PolyDADMAC coagulant in powder and liquid bead forms, and polyamine liquid coagulant for drinking water and wastewater clarification. Beyond chemicals, the company offers biological treatment products including salt-resistant COD bacteria, phosphorus removal bacteria, nitrogen-removing bacteria, anaerobic nitrifying bacteria, and denitrifying bacteria. Complementary equipment lines include CMBBR reactors, dissolved air flotation machines, electric Fenton systems, chemical dosing devices, and high-efficiency precipitators. With over 335 international trade transactions, Hengju exports primarily to Russia, the United States, Peru, and the Philippines, serving municipal sewage, mining, oilfield, paper, food, and pharmaceutical industries worldwide.
