Product Models and Core Parameters

The diagram showcases three MBR membrane curtain products, with model and key information as follows:

MBR Separate Curtain Membrane Product Characteristics:

Large Flux

Design flux is 10 - 30LMH

Good Universality

The size of installation same as the public version of membrane shell on the market.

Strong Anti-Pollution Ability

Antimicrobial PVDF hydrophilic alloy, membrane pore is uniform distribution, the ability of anti-pollution is stronger

Good Seal

Four-layer sealing technology, membrane adopts four package to eliminate water leakage on membrane shell

High Integral Strength

Internal dehulling structure, the overall strength of membrane is higher than the general products on the market

Strong Anti-Pollution Ability

Socket structure design, on-line cleaning, more convenient maintenance

Technical Advantages of MBR Membrane Curtains

MBR (Membrane Bioreactor) technology combines biological treatment with membrane separation. Core advantages include:

Stable Effluent Quality‌

High-precision membrane fibers (narrow pore size distribution) effectively remove proteins, calcium/phosphorus, whey, etc., and have excellent retention of bacteria and microorganisms, with effluent turbidity <0.5NTU.

Strong Anti-Pollution Capability‌

Special anti-pollution designs (e.g., hydrophilic modification, loose structure) reduce sludge accumulation, extend membrane life, and enable fast flux recovery after cleaning, lowering maintenance costs.

Flux and Energy Optimization‌

High-porosity membrane structure with uniform distribution minimizes water resistance, reducing operating energy by 10 - 20% compared to traditional processes.

Broad Process Adaptability‌

Modular design is compatible with industrial, municipal, and drinking water scenarios, with flexible installation and high automation.

Industry Applications and Market Background

MBR membrane curtains are widely used in wastewater treatment, especially suitable for:

● Industrial Wastewater‌: High-concentration wastewater treatment in industries like dairy, chemicals, and dyeing, solving traditional process issues such as "sludge bulking" and "unstable effluent".

● Municipal Wastewater‌: Replacing traditional secondary sedimentation tanks to simplify processes, improve automation, and reduce maintenance difficulty.

● Drinking Water/Concentration Separation‌: Achieving water purification or material concentration through membrane separation to meet specific industry needs.

Product Selection Suggestions

Selection should be based on scenario needs:

● For small wastewater treatment stations (e.g., communities, small factories), prioritize ‌QL-MBR-10‌ to balance cost and efficiency.

● For medium projects (e.g., town-level treatment plants, medium industrial lines), recommend ‌QL-MBR-15‌ to balance treatment capacity and economy.

● For large projects (e.g., city treatment plants, large industrial parks), choose ‌QL-MBR-20‌ to meet high-load treatment requirements.

For more detailed technical parameters (e.g., material, operating pressure, cleaning cycle), refer to professional supplier materials or industry standards for further confirmation.
