Zhongsheng Environmental industrial RO systems deliver ultra-pure permeate at recovery rates up to 95%, serving pharmaceutical, semiconductor, food & beverage, and power generation applications worldwide. Fully automated PLC-controlled operation with continuous output and minimal chemical consumption.
Reverse osmosis (RO) is a pressure-driven membrane separation process that forces feedwater through semi-permeable membranes, rejecting dissolved salts, organics, colloids, and micro-organisms to produce high-purity permeate. Zhongsheng Environmental's industrial RO water treatment systems are engineered for continuous, unattended operation across a wide range of capacities — from compact skid-mounted units for small facilities to large-scale multi-train configurations for municipal and heavy-industrial applications. Every system ships factory-tested and ready for rapid commissioning.
Feedwater is first pre-treated (typically via multi-media filtration, activated carbon adsorption, and antiscalant dosing) to protect downstream membranes. A high-pressure pump then forces the pre-treated water through spiral-wound polyamide thin-film composite (TFC) membrane elements. Water molecules pass through the membrane while dissolved salts, heavy metals, bacteria, and organic compounds are rejected and discharged as concentrate. The permeate is collected, post-treated (pH adjustment, remineralization, or EDI polishing as required), and delivered to the point of use. An integrated CIP (Clean-in-Place) system automates periodic membrane cleaning to maintain flux and rejection performance over the membrane's service life.

Zhongsheng Environmental has delivered hundreds of industrial RO installations across Asia, the Middle East, and Africa. Our systems are built around premium membrane elements and corrosion-resistant materials, backed by in-house process engineering that optimises recovery, energy consumption, and membrane life for your specific feedwater chemistry. From initial water analysis through commissioning and long-term membrane management, our team provides a single point of responsibility — so you get reliable, specification-grade water with the lowest total cost of ownership.
Up to 95%, minimizing raw water consumption and concentrate discharge.
Drinking water purification, mineral/spring water production, food & beverage processing, pharmaceutical ultra-pure water, electronics manufacturing, industrial boiler feed water, seawater desalination, and brackish water treatment.
No, unlike ion exchange systems, RO operates continuously without acid/alkali regeneration cycles.
Multi-media filtration, activated carbon adsorption, and antiscalant dosing to protect membrane elements.
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 multi-media filters remove suspended solids, turbidity, and colloidal matter from raw water, achieving SDI values suitable for downstream RO membrane protection. Robust, low-maintenance vessels with long-life filter media and automated backwash.
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.
