Integrated MBR membrane bioreactor system combining activated sludge treatment with submerged PVDF membrane filtration. Delivers near-reuse-quality effluent (<1 μm filtration) with 60% smaller footprint than conventional systems. Ideal for municipal sewage, industrial process water, and water reuse projects from 10 to 2,000 m³/day.
The Zhongsheng MBR Integrated Wastewater Treatment System combines advanced membrane bioreactor (MBR) technology with biological treatment in a single, factory-assembled package. By replacing the conventional secondary clarifier with submerged PVDF ultrafiltration membranes, this system achieves superior effluent quality — with virtually all particles larger than 1 μm removed — making the treated water suitable for direct non-potable reuse including irrigation, industrial process water, cooling tower makeup, and toilet flushing.
The integrated design delivers all the advantages of MBR technology in a compact, pre-engineered unit that can be deployed rapidly with minimal civil works, meeting or exceeding EU Directive 91/271/EEC, US EPA Guidelines for Water Reuse, and WHO water reuse recommendations.
The integrated MBR system operates on a two-zone biological process:
The membrane barrier maintains biomass concentration at 7,000–18,000 mg/L — approximately 5 times higher than conventional activated sludge systems. This dramatically increases volumetric treatment efficiency while allowing independent control of hydraulic retention time (HRT) and sludge retention time (SRT) for process optimization.

Zhongsheng MBR systems deliver the gold standard in compact wastewater treatment — near-reuse-quality effluent from a footprint 60% smaller than conventional plants, with no clarifier to maintain and no sludge bulking to worry about. Whether you are building a new treatment facility, upgrading an aging plant to meet tighter discharge limits, or implementing a water reuse program, our integrated MBR packages arrive factory-tested and ready for rapid installation. With proven PVDF membrane technology, fully automatic PLC control, and a track record across municipal, commercial, and industrial applications, the Zhongsheng MBR is engineered for reliable, low-cost operation over the long term.
The MBR system achieves CODcr ≤60 mg/L, BOD₅ ≤20 mg/L, NH₃-N ≤15 mg/L, and SS ≤20 mg/L, meeting China Class 1A discharge standard.
MBR offers a smaller footprint, superior effluent quality, 80% less sludge production, and eliminates the need for a secondary clarifier.
Yes, the MBR system is ideal for upgrading existing municipal and industrial treatment plants to meet stricter discharge standards.
MBR membranes last 5–8 years with proper maintenance and automated chemical cleaning (CIP).
