Product Description

Integrated Membrane Bioreactor(MBR) Wastewater Treatment Module
& Flexible Flat Sheet Membranes

Introduction:
We are a leading flexible flat sheet membrane manufacturer independently developing the component with first fully automatic production line from formula to film scraping machine to forming and assembling and we 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 floor area 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 Unit:
20t/H High Performance Industrial Mbr Wastewater Treatment Integrated Module Manufacturer

Our LR flexible flat sheet membrane stack 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 on 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 will be collected to the central water collecting pope 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.

Notes: The filtration capacity of membranes module is obtained according to the membrane area multiply by flux. It's suggested that the flux of municipal sewage seen as 400L/dayxsquare meter, please calibrate the flux for industrial sewage. The water yield in the table is calculated according to the effective working time of 20h per day while the operating mode is running for 8 minutes and stopping for 2 minutes, or running for 9 minutes and stopping for 1 minute.

Typical Discharging Effluent Quality:
TSS < 2mg/L
Turbidity < 0.1NTU(Ultrafiltration), 1NTU(MBR)
COD decline, COD would be controlled under 50mg/L while the biochemical system is well treated
NH4-N decline, NH4-N would be controlled under 1mg/L while the biochemical system is well treated

Pipeline Connection Diagram for Membranes Assembly Module:

20t/H High Performance Industrial Mbr Wastewater Treatment Integrated Module Manufacturer
As shown in the figure, the membranes module is connected to three main pipelines: output water pipeline, backwash pipeline and aeration pipeline. The water collecting port is connected with the water output pipeline and the backwash pipeline through a three-way connection. The backwash pipeline is connected to the high-level cleaning water tank which can backwash the membranes with cleaning water or solution. The water tank is 0.5-1 meters higher than the membrane assembly module, so the solution in the tank can be injected into the diaphragm by gravity or backwash pump. The aeration pipeline is connected to the air inlet of the membranes module while the other end of the membrane module is a vent with a vent valve which mainly play the role of flushing the aerator.

Applications:
Underground water -- Ultrafiltration
Surface water -- Chemically enhanced ultrafiltration or ultrafilter directly
Lightly polluted water/Tertiary treatment -- Chemically enhanced ultrafiltration/MBR
Sewage -- MBR
Domestic sewage integrated equipment
Industrial ultrafiltration equipment
Secondary sedimentation tank
Printing and dyeing wastewater tank modifying and upgrading
Pharmaceutical wastewater tank modifying and upgrading
