The core of MBR technology is membrane modules; Yimeng Company has developed E-MEM through the development of independent patents (specific patents as described in detail), the introduction of advanced production equipment, and the development of E-MEM ® The MBR membrane product uses PVDF (polyvinylidene fluoride) as the film-forming material, which has the characteristics of high tensile strength, high chemical stability, high filtration accuracy, simple operation, and low energy consumption. At present, the product has been widely used in municipal sewage treatment, surface water treatment, and reclaimed water reuse.

Product features

Zhejiang E-MEM curtain-type MBR membrane is produced by own patent composite spinning technology. On the surface of the textile tube, it is the high-performance separating layer of PVDF. By optimizing the formula of separating layer and the craft of surface pretreatment, it makes the hollow fiber of MBR featured with super-high tensile strength and high separation accuracy.

E-MEM MBR application：

Ø Drinking water treatment, the removal rate of ultrafiltration membrane can reach 61og for bacteria and 41og for viruses, so water plants and water users do not need to worry about bacteria and viruses, in same time the recovery rate can be 99%

Ø Surface water treatment，used for irrigation or as water for reverse osmosis to prepare purified water.

Ø Seawater treatment pretreatment, MBR system can control the water quality of seawater very confidently, provide high quality water entry for reverse osmosis system, and ensure the stable operation of reverse osmosis system.

Ø Wastewater recycling to meet industrial reclaimed water usage.

Product performance characteristics

Super-high strength hollow fibers, stable good water quality

Ø PVDF material is excellent of chemical resistance, it is not easy to corrode by acid and alkali, strong oxidant and halogen, etc.

Ø 0.1um membrane pore size and distributed averagely, which can effectively remove almost all suspended matter, bacteria, colloid and particles in water, ensuring the produced water quality. The suspended matter and turbidity of effluent water are zero and can be directly reused.

Ø Achieves absolute separation between HRT and sludge age.

Ø Supporting fiber system make strength of hollow fiber greater than 150N and instant burst pressure 0.45MPa

Ø The concentration of microorganisms in the reactor was as high as 5000~10000mg/L, with high biochemical efficiency and strong impact load resistance.
