        MCR Membrane Module Reinforced PVDF BM-SLMCR-20 RO Pretreatment

        ●?Unique gradient reticular?pore structure, high filtering precision and good output quality;

        ●?Unbreakable hollow fibers, 3-layer protective structure, hollow fibers are not easy to fall off, service life can reach 5 years +;

          Product?Overview

          Submerged ultrafiltration (MCR) Technology is a water treatment technology which combines membrane technology and physico-chemical precipitation process. High-precision sludge-water separation of outlet from coagulation sedimentation tank can ?be? done? by? submerged? ultrafiltration? (MCR),? high? filtering? precision? of memrbane insures high quality and clear water outlet.

          This product adopts reinforced modified PVDF material, which will not peel or break ?during? backwashing,? meanwhile? it? has? good? permeable? rate,? mechanical performance, chemical resistance and anti-fouling? ability. ID? & OD of reinforced hollow fiber membrane are 1.0mm and 2.2mm respectively, filtering precision is 0.03 micron.? Filtering? direction? is? outside-in,? that? is raw? water,? driven by? differential pressure, permeates into the hollow fibers, while bacteria, colloids, suspended solids and microorganisms etc. are rejected in the membrane tank.

          Applications

          ● Purification of surface water;

          ● Reuse of heavy metal waste water;

          ● Pretreatment of RO.

          Filtration?Performance

          Below? filtration? effects? are? proved? according? to? the? use? of modified ?PVDF hollow fiber ultrafiltration membrane in different types of water:

          No. Item outlet water index

          Using?Conditions

          Proper?? pretreatments ??must?? be?? set?? when?? raw?? water?? contains?? a?? lot?? of impurities/coarse particles or large proportion of grease. Defoamer must be used to remove ?foams? in membrane tank when necessary, please use? alcoholic? defoamer which is not easy to scale.

          Item Limit Remark
          PH Range 5-9 (2- 12 when washing) Neutral PH is better for bacterial culture
          Particle Diameter <2mm Prevent sharp particles to scratch membrane
          Oil & Grease ≤2mg/L Prevent membrane fouling/sharp flux decrease
          Hardness ≤150mg/L Prevent membrane scaling

          Application?Parameters:

          Designed Flux 15~40L/m2.hr
          Backwashing Flux Twice the designed flux
          Operating Temperature 5~45°C
          Maximum Operating Pressure -50KPa
          Suggested Operating Pressure ≤-35KPa
          Maximum backwashing Pressure 100KPa
          Operating Mode Continuous opeartion, intermittent backwashing air flushing
          Blowing Mode Continuous Aeration
          Aeration Rate 4m3/h.piece
          Washing Period Clean water backwashing every 1~2h; CEB every 1~2 days;Offline washing every 6~12 months(Above information is for reference only, please adjustaccording to actual differential pressure change rule)
