Custom-engineered solutions for every application
WSZ series underground integrated sewage treatment plant combines anoxic/aerobic (A/O) biological contact oxidation with sedimentation and disinfection in a single buried package unit. Fully automated with no operator required, it handles 1–80 m³/h for residential communities, hotels, hospitals, factories, and rural areas. Can be installed below grade with landscaping above, or mounted on a trailer for mobile deployment.
ZSQ series dissolved air flotation (DAF) system for high-efficiency removal of suspended solids, FOG, oil & grease, and colloidal matter from industrial wastewater. Micro-bubble technology with automatic skimming handles 4–300 m³/h across 13 standard models. Proven in food processing, pulp & paper, textile, metalworking, petrochemical, and municipal pre-treatment applications.
JY series all-in-one water purification system integrates coagulation, flocculation, sedimentation, filtration, and automatic backwash in a single compact unit. Fully automatic operation treats surface water with turbidity up to 3,000 mg/L to below 3 mg/L. Ideal for rural water supply, small towns, industrial process water, and mine water treatment with capacities from 10 to 200 m³/h.
Zhongsheng Environmental automatic chemical dosing systems provide precise, PLC-controlled injection of coagulants, flocculants, pH adjusters, and specialty chemicals for water and wastewater treatment. Skid-mounted, pre-wired, and factory-tested for rapid installation.
Zhongsheng Environmental plate and frame filter presses deliver efficient solid-liquid separation for municipal and industrial sludge dewatering, with filtration areas from 1 m² to 500 m² and manual, hydraulic, or fully automatic PLC-controlled operation.
The ZS Series Chlorine Dioxide Generator produces high-purity ClO₂ disinfectant on-site using proven chemical or electrolytic methods. Available in eight configurations — from compact manual units (50 g/h) to fully automated industrial systems (20,000 g/h) — these generators deliver reliable microbial control for municipal drinking water, hospital effluent, industrial cooling loops, and process wastewater. Compliant with EPA, EU Drinking Water Directive 98/83/EC, and WHO Guidelines for Drinking-water Quality.
