Belt Filter Type Thickeners: Efficient Solid-Liquid Separation Solution

The Belt Filter Type Thickeners is a high-efficiency solid-liquid separation equipment designed for concentrating and dewatering various slurries in industrial processes. It integrates advanced filtration technology with stable mechanical structure, providing reliable performance for customers in different industries. With its compact design and easy operation, this equipment effectively reduces the moisture content of materials, improves production efficiency, and lowers overall operating costs.

Integrated Water Treatment Dosing System

Introducing our Integrated Water Treatment Dosing System, a versatile and intelligent 100% customized solution engineered to meet the precise dosing demands of multiple water treatment scenarios-including tap water purification, cooling tower circulating water maintenance, boiler water quality control, and sewage treatment. This all-in-one system integrates chemical storage, automatic preparation, precise dosing, real-time monitoring, and intelligent control into a compact unit, eliminating the inefficiency of split-type equipment and delivering consistent, cost-effective water treatment performance tailored to your specific needs across industries.

PAC/PAM Dry Powder Automatic Dosing Machine

The PAC/PAM Dry Powder Automatic Dosing Machine is a high-precision, fully automatic chemical dosing equipment designed for the preparation and dosing of polyaluminum chloride (PAC) and polyacrylamide (PAM) dry powder solutions. It integrates automatic water inflow, precise dry powder feeding, uniform stirring, and liquid level control into a compact system, ensuring the stable preparation of chemical solutions with accurate concentrations.

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.
