VONTRON Membrane Technology Co., Ltd. is a fully owned subsidiary of CRRC South Huitong and is dedicated to the R&D and manufacturing of reverse osmosis, nanofiltration membranes, ultrafiltration membranes and membrane elements. Our core technology is membrane manufacturing with an exceptionally strong system design capability, ensuring we provide our customers with high quality application and technical support services. At Vontron, we are one of the world’s leading manufacturers of spiral wound separation membranes, with an annual production capacity of 30 million square meters of composite reverse osmosis membranes and nanofiltration membranes.

In 2001, VONTRON introduced a membrane and spiral wound membrane components production line and process technology from the United States. Through research, development, and continuous innovation, after more than 18 years of growth, we produced 12 series of membrane products in more than 70 different specifications, including desalination membranes, fouling resistant membranes, oxidation resistant membranes, nanofiltration membranes, special separation membranes and water-efficient residential membranes. These membranes are then used in bottled water, municipal drinking water, industrial pure water, electronic high-purity water, seawater desalination, brackish water desalination, waste water reuse, high-salinity salts and near-zero emission, food and beverage, medical and pharmaceuticals, material separation and concentration, and purification applications and industries. Vontron products can be found in more than 130 different countries and regions around the world.

As the R&D and application platform for the National and Local Joint Engineering Center for Separation Membrane Materials and Application Technology, VONTRON has undertaken eight major national science and technology projects, including 863 national science and technology support plans, national key R&D plans and more. In the 16 years since 2004, our company has been granted 93 patents, including 38 invention patents and 2 national key products. VONTRON participates in the formulation of 12 national and industry standards, 3 of which have been subsequently implemented. Our R&D platform is composed of a high-tech talent team and high-end equipment that provides a strong technical guarantee for VONTRON's consistent, continuous and rapid development.

VONTRON's membrane manufacturing base is located in the Guiyang State High-tech Industrial Development Zone, covering an area of 20,000 square meters, with a construction area of 68,000 square meters. Using highly automated equipment, a production environment with strict standards and quality control, Vontron has created a high-performance automatic dry membrane production line and a fully automatic membrane rolling production line, representing our core manufacturing technology. With a cleaner production environment and an environmental protection treatment system covering the full plant area, we are dedicated to doing our part to usher in a greener future.
