Green Low-Carbon Prefabricated Membrane Filtration Water Purification Plant
Short construction period | Small footprint | Low investment cost | Low operating cost
For small to medium-sized water purification projects, the prefabricated integrated water purification plant has proven to be comprehensively superior to traditional steel-reinforced concrete structures in terms of construction period, investment, land use, and green low-carbon performance. Our products precisely address industry challenges, delivering full-scenario solutions that are efficient, land-saving, time-saving, and worry-free.
Safe Structure
ZCEN has established the Prefabricated Water Plant Innovation R&D Base with the China Institute of Building Standard Design & Research, focusing on R&D and design of steel structures for prefabricated water plants to build a safe and low-consumption structural system.
Advanced Process
Our product adopts a water purification process train integrating mixing, flocculation, sedimentation, submerged ultrafiltration (UF) membrane filtration, and disinfection. The system consists of an integrated water purification unit (incorporating flocculation, sedimentation, and submerged UF membrane filtration modules) together with auxiliary facilities.
The treated water quality not only consistently meets the requirements of the current national standard Standards for Drinking Water Quality (GB 5749-2022), but also achieves turbidity below 0.1 NTU — with significantly enhanced biological safety, reduced disinfectant dosage, and fewer disinfection by-products.
Leveraging artificial intelligence and IoT technologies, we have built a smart, safe, and stable prefabricated membrane filtration water plant capable of unattended operation.

Features
Shorter Construction Period & Lower Costs
Innovative steel corrugated plate design: The sinusoidal wave design saves 15%–20% of material compared to conventional trapezoidal plates.
Optimized structure, reduced thickness: Achieves equivalent strength with thinner plates. Factory standardized production minimizes on-site construction losses, reducing overall cost by 20%.
Modular prefabrication: Main structural modules are pre-formed in the factory, each with a unique IP number and full traceability. On-site modular assembly shortens construction time by approximately 70% compared to conventional water plants (e.g., a 50,000 m³/day project takes only 80 days).
Advanced Technology & Stable Performance
Superior effluent quality: With a pore size of ≤0.1μm, the membrane effectively removes suspended solids, colloids, bacteria, algae, and most viruses. Treated water turbidity is consistently below 0.1 NTU, with significantly enhanced biological safety, reduced disinfectant dosage, and fewer disinfection by-products.
Stable operation: Mature water purification process with submerged membrane tanks offering strong resistance to hydraulic shock loads.
Long service life: Equipment ensures stable long-term operation (≥20 years); UF membrane modules last ≥5 years.
Site-Adaptable & Flexible Configuration
Multiple optional sub-modules allow flexible customization for each project based on water demand, construction, O&M, and investment requirements – delivering the most suitable water treatment solution.
High membrane module compatibility facilitates phased expansion or replacement of membrane components.
Modular design enables repeated disassembly, relocation, and high reusability.
Smart Monitoring & Unattended Operation
Optional Zhongchang Smart Cloud Control System: Digital twin process simulation + cloud-based expert model analysis enable precise control of operating parameters. Combined with intelligent monitoring, it reduces costs, increases efficiency, and minimizes manual intervention.
Mobile APP / Web access for real-time operating data, fault alerts, and remote adjustment of backwash cycles and chemical dosing rates.
Automatic response to abnormal conditions: When online monitoring detects anomalies in raw water turbidity, pH, algae, or other indicators, the system automatically initiates enhanced backwashing, adjusts chemical dosing, and simultaneously pushes alerts to the cloud O&M platform – enhancing emergency response capability and ensuring water supply safety.
Green Energy Integration
Optional PV energy storage system: Stores energy on sunny days and ensures continuous operation on cloudy days, reducing overall electricity costs by over 40%.
Application Scenarios
Green Low-Carbon Prefabricated Membrane Filtration Water Purification Plant is suitable for treating raw water from rivers, lakes, reservoirs, streams, wells, and other sources. It effectively removes turbidity, color, algae, and microorganisms caused by suspended solids, colloids, and the like. The treated water quality consistently meets the requirements of the current national standard Standards for Drinking Water Quality (GB 5749-2022), with effluent turbidity below 0.1 NTU. Biological safety is significantly enhanced, while disinfectant dosage and disinfection by‑products are reduced.
| Comparison Dimension | Submerged UF Membrane (IMF) | V-Type Filter (Uniform Grain Sand Filter) |
| Filtration Principle | Physical screening (membrane pore size 0.01–0.1μm), removing suspended solids, colloids, bacteria, and viruses | Granular bed filtration (uniform quartz sand, grain size 0.9–1.3mm), relying on deep-bed retention and surface adsorption |
| Effluent Turbidity | ≤0.1 NTU (typically <0.05 NTU), consistently meeting Standards for Drinking Water Quality (GB 5749-2022) | ≤0.5 NTU (design value), subject to raw water fluctuations, may range 0.5–2 NTU |
| Shock Load Resistance | High (influent turbidity up to ≤30 NTU can still produce effluent <0.1 NTU, provided coagulation pretreatment is stable) | Moderate (influent turbidity >10–15 NTU may cause breakthrough, requiring frequent backwashing) |
| Footprint | Small (land saving of approx. 30%) | Large |
| Applicable Scenarios | High-quality effluent required, raw water quality fluctuates significantly, land-constrained sites, sand filter retrofitting/upgrading | Stable raw water turbidity, low temperatures, low biological risk in treated water |
| Microorganism Removal | >99.99% (effective removal of Cryptosporidium and Giardia) | Limited (relies on coagulation/sedimentation; virus/cyst removal rate <90%) |
| Selection Recommendation | For projects pursuing high effluent quality and water supply safety; can also be installed in series after existing filters | For projects where cost-effectiveness is the primary consideration |
