MBR process VS traditional wastewater treatment process.

You can see MBR module systems replace the Clarifier, Sand filter and Disinfection processes used in Conventional Activated Sludge (CAS) process by removing the suspended materials with UF/MF membrane. The membrane modules are submerged in a biological tank or side streams tank, with the water being drawn through the membranes under vacuum, leaving the suspended biomass material in the biological aeration tank. The MBR systems have a smaller footprint than CAS systems, produce consistent effluent quality even in varying influent conditions
It is now widely used for municipal and industrial wastewater treatment.
RisingSun flat sheet membrane is made of PVDF material, which has better chemical stability, fouling resistance and mechanical strength. With advanced membrane fabrication technology, we control the membrane pore size around 0.1 um to get a higher water flux and water quality.
Benefits:
The mortise and tenon structure is used in the support plate to get a more stable spacing without side panels. The support plate can be installed from top or one side without the limits of the construction site conditions.
