0.7mm Thickness Mbr/UF Flat Sheet Membrane for Industrial Water Treatment Equipment

Integrated Membrane Bioreactor(MBR) Wastewater Treatment Module &Flexible Flat Sheet MembranesIntroduction:We are a leading flexible flat sheet membrane manufacturer mainly specialized in flat-sheet membrane rolls with PVDF material, which are suitable for MBR and immersion ultrafiltration. PVDF's non-viscosity (low surface energy) gives it better pollution resistance. We adopt permanent hydrophilic modification, which can optimize the pollution resistance and flux. CPVC molecule has a lot of negative covalent bond chlorine in it, which makes the surface of the material more negatively charged, while most of the impurities in the wastewater are electronegative, so the fouling resistance property is also very good.Our LR Series flexible flat sheet membrane module not only retains  the advantages of conventional flat membrane like high strength, easy maintenance, no backwash, high flux and low transmembrane pressure difference, but also include the advantages of hollow fiber membrane like high filling density, small footprint and lower gas-water ratio. At the same time, our products have the advantages of  extreme low replacement cost of single membrane, high welding strength and backwash available. Our MBR membrane wastewater treatment system can replace traditional biological wastewater treatment technology on a large scale and wide application ranges.Membranes Stack/Cassette Unit:LR flexible flat sheet membrane stack/cassette consists of rectangle membrane, sealing ring, spacing strip, central water collecting pipe and two ends baffles. Membranes and sealing rings are putted on the center pipe one by one and then pressed and sealed by the baffles on both sides. After filtered by the membranes the wastewater first enters the support passage and then collected to the central water collecting pipe for export with the activated sludge keeping out of the diaphragm. The pore size of these membranes is 0.03-0.1μm while the material is most commonly used PVDF.Basical Parameters of LR Membrane Stack/Cassette:ModelLR4LR8LR9Membrane Size (mm)250x250250x250250x250Membrane Spacing (mm)488Average Thickness (mm)0.70.70.7Membrane Count (pcs)182114208Stack Area Size (m2)2012.523Stack Outline Dimension (mm)528x520x252528x520x252528x920x252Membrane MaterialPVDFPVDFPVDFDischarging Pipe Count222Flow Rate (L/H)200-600125-375230-690Working Pressure Differential (m)0.2-60.2-40.2-4ApplicationImmersed UltrafiltrationMBRMBRpH2-12Discharging Water Turbidity≤1NTUFlat Sheet Membranes MBR Module:The basic structure of LR flat sheet membrane assembly module mainly contains three parts as shown in the following figure: aeration part, membrane box part and water collecting pipe part.Features:• Ultra thin membrane design, average 0.7mm• High packing density, smaller footprint• Welding strength x5 times stronger due to optimized memebrane forming technique• Single membrane can vibrate/swing under aeration just like hollow membrane• Single membrane and single MBR stack/cassette can be replaced easily• Good hydrophilicity and fouling resistant• High adsorption to substrate material and backwash applicable• High loading density, high water-air ratio, low operating cost• Low transmembrane pressure• General frame adopting gravity-buoyancy balance design, high stability, long service life• Membranes stack unit can be demounted and maintained online• Reasonable module size, flexible installation design• Super-high cost effectiveComparison Between LR Flexible Flat Sheet Membrane and Hollow Fiber Membrane:ItemLR Flexible Flat Film Hollow Fiber FilmConventional Flat FilmFlux/LMH10-3010-2010-30Loading DensityEquivalentLowAir Quantity per Water Treatment UnitEquivalentHigherBackwash Required or NotNo(Available if required)YesNot ApplicableWobble or NotYesYesNotMembrane Silk Can Broke or NotNotYesNotService LifeLongShortLongPre-filtration Requirement (Gird Diameter)2mm1mm2mmOffline Cleaning Needed or NotNot UsuallyYesNot UsuallyTranmembrane Pressure Differential (m)0.05-0.30.1-0.60.06-0.3Investment Cost/Operating CostLow/LowLow/HighHigh/HighLR Standard MBR Membrane Module:ModelMembrane Stack LayersCountMembrane Stack ColumnsCountMembrane Stack CountTotal Membrane AreaOutline Size(L×W×H)DomesticSewage Treatment CapacityIndustrial Sewage Treatment Capacitym2mmt/dt/dLR8-1-212225.0700x700x1230107.5LR8-1-414450.01250x700x12302015.0LR8-2-323675.01000x700x17703022.5LR8-2-4248100.01250x700x17704030.0LR8-2-52510125.01500x700x17705037.5LR8-2-62612150.01750x700x17706045.0LR8-3-53515187.51500x700x24407556.2LR8-3-63618225.01750x700x24409067.5LR8-3-83824300.02250x700x244012090.0  ModelMembrane Stack LayersCountMembrane Stack ColumnsCountMembrane Stack CountTotal Membrane AreaOutline Size(L×W×H)DomesticSewage Treatment CapacityIndustrial Sewage Treatment Capacitym2mmt/dt/dLR9-1-212246.0700x1100x123018.413.8LR9-1-414492.01250x1100x123036.827.6LR9-2-3236138.01000x1100x177055.241.4LR9-2-4248184.01250x1100x177073.655.2LR9-2-52510230.01500x1100x177092.069.0LR9-2-62612276.01
