Domestic Compact MBR Membrane Module 5-1000 m³/d for Sewage Treatment Plant

Membrane maintenance is where MBR systems are won or lost. Complex disassembly, tank draining, and long downtime turn a routine cleaning into a production problem. Zhongqiao Enlightenment designed its MBR membrane module to make maintenance genuinely easy: the module is quick-detachable, offline cleaning requires no draining of the MBR tank, and a dual aeration system — external plus internal — actively prevents the membrane blockage that forces frequent cleaning in the first place. The result is a membrane system that spends its life producing clean water instead of waiting for maintenance.

Maintenance Designed Around the Operator

Every detail of this module is arranged around fast, safe, low-effort maintenance. The quick-plug connectors and quick-detachable structure let operators remove a membrane module or curtain without draining the tank, so cleaning or replacement happens in hours, not days. The dual aeration system scours the membrane from both outside and inside, keeping sludge from accumulating on the fiber surface and inside the bundle — the two places where fouling usually begins. And because the membrane curtain headers are cut through a three-step process (rough cutting, heating treatment, precision cutting), the filament through-hole rate exceeds 98%, so the entire membrane area is always available for filtration.

Key Features

• Quick-detachable module design: efficient disassembly and assembly; offline cleaning without draining the MBR tank saves water, time, and labor.
• Dual aeration prevents membrane clogging: internal aeration added on top of the original external aeration effectively protects the membrane and extends service life.
• Quick-plug connectors for easy disassembly, assembly, and maintenance of membrane modules.
• Filament through-hole rate above 98%, achieved by rough cutting, heating treatment, and precision cutting of membrane headers.
• Double-layer sealing rubber ring for superior sealing performance at every connection.
• Uniform filament arrangement with 0.8 mm (±0.1 mm) spacing: high packing density, smaller footprint, and lower operational energy consumption than comparable systems.

Applications

Easy maintenance matters most where access is difficult and staffing is limited: underground and semi-underground sewage stations, packaged and containerized treatment plants, decentralized community systems, hotels, hospitals, and commercial buildings with basement equipment rooms, industrial facilities where production cannot pause for membrane work, and remote sites where skilled technicians are scarce. For these installations, the quick-detachable module combined with dual aeration keeps both membrane performance and maintenance burden under control.

Lower Lifetime Cost Through Better Design

The maintenance-friendly design is not just a convenience — it is a financial advantage. Less downtime means more treated water per day. No tank draining means less wasted biomass and chemical dosing. Fewer blockages mean fewer cleaning cycles, less membrane stress, and a longer service life. When the membrane does eventually need replacement, quick-plug connectors make the swap fast and inexpensive. Add the traceable curtain coding, the 40 kg fiber tensile strength, and the < 0.1% breakage rate, and the total cost of ownership becomes decisively lower over the system’s lifetime.

A Simple Maintenance Workflow

Daily: record permeate flow and trans-membrane pressure (TMP). A slowly rising TMP at constant flow is the first sign of fouling — start with a backwash. Weekly: observe the aeration pattern across the module; uneven bubbling indicates a blocked diffuser or a fouled bundle that needs attention. Monthly: inspect the double-layer sealing rings and quick-plug connectors for wear. When TMP exceeds the threshold or flux has dropped about 20%, schedule a maintenance clean: pull the curtain offline with the quick-detachable mechanism — no tank draining, no pump removal — soak in hypochlorite, rinse, and return it to service within hours.

Replacement is equally fast: a single curtain can be swapped in roughly 30 minutes thanks to the quick-plug connectors, and because every curtain is traceable by code, you can order a replacement matched exactly to your installed specification — 7, 10, 15, 20, or 35 m² per piece.

Why Dual Aeration Works

Single external aeration cleans the outside of the fiber bundle, but sludge can still accumulate in the dense center where bubbles rarely reach. Our dual aeration adds internal aeration that delivers air into the heart of the bundle, scouring the innermost filaments that external bubbles cannot touch. The combination prevents membrane blockage from both directions, keeps the entire membrane area productive, and reduces the frequency of chemical cleaning — which in turn reduces membrane stress and extends service life. For operators, the benefit is simple: fewer interventions, more uptime, lower chemical and labor cost over the life of the plant.

Support does not stop at delivery. Every membrane system from Zhongqiao Enlightenment includes documentation for the full maintenance program — recommended backwash cycles, cleaning chemical concentrations, and aeration settings — plus operator training options so your team can run the plant confidently from day one. Spare curtains and sealing rings are kept in production, and because all curtains in the 7–35 m² range share the same fiber specification, stocking one or two spares covers most contingencies. Our after-sales team is reachable for troubleshooting, and the traceable curtain codes mean a support call starts with your exact product history, not a guessing game.
