A revolutionary product disrupting traditional MBR
High flux (30~35LMH)
After five years of experimental research and engineering applications, the membrane technology R&D team has successfully developed a special ultrafiltration membrane —— large-flux flat sheet membrane DMBR. Using PVDF + EVOH special composite material modification technology to improve the membrane formulation and process, optimizing the membrane pore structure, reducing the transmembrane resistance, making the membrane sheet have better hydrophilic properties, the membrane flux is increased by 30% compared to traditional formulations, offering better cost-effectiveness.
Under the same influent conditions:
Lower investment and price costs
The DMBR membrane flux is about 0.5~0.8 times that of traditional MBR flat sheet membranes, approximately 1-~1.5 times that of MBR hollow fiber membranes. In the same circumstances, less membrane area is required, the investment is comparable to MBR hollow fiber membranes, but 50% lower than traditional MBR flat sheet membranes, resulting in even lower investment costs.
Lower operation and maintenance costs
Under the same operating conditions, DMBR membranes require less usage, smaller aeration volume, reduced blower energy consumption, equivalent to MBR hollow fiber membranes, but 50% lower than traditional MBR flat sheet membranes. DMBR membranes have a lower cleaning frequency, consume less chemicals, saving around 50% on chemical costs compared to traditional flat sheet MBR membranes.
Lower membrane depreciation costs
The service life of DMBR membranes is more than 5 years, whereas MBR hollow fiber membranes last only 1~3 years, resulting in lower membrane depreciation costs.
