We adhere to the principle of "leading with technology and thriving through quality," continuously reforming and innovating. We have expanded our production scale twice and developed new products. Our company has evolved from a single filter material to four series today: water treatment filter materials, water treatment fillers, water treatment reagents, activated carbon, and pipeline accessories. With over thirty product types and more than a hundred specifications, we have gradually formed an integrated enterprise encompassing production, processing, sales, and installation. Since its establishment, Henan Haoran Water Treatment Co., Ltd. has always adhered to the principles of leading with technology and thriving through quality. In collaboration with several research institutions (departments) both domestically and internationally, we have jointly developed a series of efficient, energy-saving, and durable water treatment products widely used in various sectors such as urban water supply and drainage, chemical industry, oil fields, metallurgy, thermal power, papermaking, pharmaceuticals, environmental protection, sewage treatment, and abrasives. These products have been recognized by experts from relevant departments including the China Municipal Engineering Design Institute and the Filter Material Testing and Inspection Center. They have also received positive feedback from both domestic and international users, including Japan and South Korea, as well as the Three Gorges Project. The physical properties of these products are excellent, their chemical stability is high, the grading is appropriate, and they have a long service life. For this, our products have been honored with titles such as "Inspection-Free Product" and "Preferred Recommendation Product" by units like the China Water Supply and Drainage Standards Committee.
