Full-scenario Coverage, Customized Adaptation
It covers multiple fields such as sewage treatment, industrial discharge, river monitoring and pure water systems, and supports customized parameter combination schemes to meet the personalized water treatment needs of different scenarios.
Our Series Of Products
Polymerization Inhibitor Dosing System
Polymerization Inhibitor Dosing System is widely applied in chemical, polyester, acrylic, resin, oil and gas, circulating water and other industrial processes. It is designed for the accurate dosing of polymerization inhibitors to suppress material polymerization, gelation and self-polymerization. The system effectively prevents pipeline blockage, reaction runaway and product deterioration, ensuring long-term stable and continuous production operation.
Antiscalant Dosing System
The antiscalant dosing system is a core auxiliary water treatment device widely applied in reverse osmosis (RO), circulating cooling water, boiler, and heat exchanger systems. It is designed for accurate, continuous, and automatic dosing of antiscalants. The system effectively inhibits the crystallization and scaling of calcium, magnesium, silicon, and sulfate ions, thereby protecting membrane elements, pipelines and heat exchange equipment, and improving the overall operational stability of water treatment systems.

Integrated Magnetic Coagulation Water Treatment Device
The magnetic coagulation‑sedimentation product series are advanced water purification devices developed based on our company’s RS‑Mag technology platform. They are mainly applied to advanced treatment of municipal sewage, industrial wastewater and mine water, purification of heavy‑metal‑containing wastewater, remediation of urban black‑odorous water bodies and river water regulation. These devices rapidly reduce turbidity, efficiently remove total phosphorus (TP), and deeply eliminate insoluble chemical oxygen demand (COD) and fluoride ions.
Lamella Plate Clarifiers
Lamella plate clarifier is a high-efficiency solid-liquid separation device. By installing a number of thin plates in the sedimentation and separation zone, it achieves a multiplied effective sedimentation area per unit floor space.
Underground HDPE Oil/ Water Separators
Oil drippings and spills from parking lots, driveways, oil terminals and other vehicular traffic surfaces are being washed into our water supplies by rainwater, creating serious environmental concerns. HDPE OWS provides a full range of dependable products for the oil/water separator industry.
Activated Carbon Filter Tank
The activated carbon filter is mainly used in water supply and drainage treatment systems to remove organic matter, colority and residual chlorine from water. Filling with activated carbon of different properties can achieve different treatment purposes. When applied as a pretreatment system for ion exchange, it can effectively prolong the service life of ion exchange resins, improve effluent water quality, and prevent resin poisoning and contamination that may affect normal operation.
