The MBR membrane of reverse osmosis membrane evaluation index

  Chongqing demineralized water equipment tell everyone: MBR membrane as the sewage treatment equipment (note: sewage treatment equipment is mainly including tank, mechanical filter, integrated water purifier, MBR membrane and MBR membrane biological reactor) is an important part of, has been widely used. For the MBR membrane quality, how do we evaluate? We think of MBR membrane of reverse osmosis membrane evaluation index from the following several aspects:
1, the MBR membrane desalination rate and rate of salt
  Desalination rate - by MBR membrane reverse osmosis membrane from the percentage of the system to remove the water soluble impurity concentration.
Through the salt rate - into the water soluble impurities through the percentage of the membrane. Desalination ratio = (1 - water salinity/water salinity) x 100%
2, the MBR membrane water rate (water flux)
  Water rate (water flux) - refers to the capacity of the MBR membrane reverse osmosis system, water through the membrane, per unit of time, usually with tons/hour or gallons per day.
  Seepage flow rate, seepage flow rate also said the MBR membrane reverse osmosis membrane element of the important indices for water rate. Refers to the unit through the liquid flow rate on membrane area, usually expressed in gallons per square foot (GFD) every day. High osmotic flow rate will lead to accelerated perpendicular to the membrane on the surface of the water flow, aggravate membrane fouling.
3, MBR, the recovery rate of membrane
  Chongqing well water purification equipment to tell everyone: - refers to the recovery of the MBR membrane water into water production of the system, or through the percentage of the fluid. MBR, the recovery rate of membrane system has been determined, when the design is based on the water quality of the preset ?
