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.
Nutrient Dosing System for Hydroponics and Greenhouse Fertigation
Our Nutrient Dosing System is a high-precision, automated solution designed to deliver essential nitrogen and phosphorus supplements tailored to wastewater treatment processes.
By precisely regulating nutrient input, the system ensures that microorganisms in biological treatment units maintain optimal metabolic activity, thereby guaranteeing efficient nutrient removal (such as total nitrogen and total phosphorus) and stabilizing effluent water quality. The skid-mounted integrated design simplifies on-site installation, reduces space occupation, and facilitates unified maintenance and management. It is widely applicable to various biological treatment scenarios, effectively solving problems such as insufficient indigenous nutrients in wastewater and reduced treatment efficiency caused by seasonal fluctuations.
