PTFE/PVDF MBR Water Treatment Water Treatment Equipment Membrane System

PTFE / PVDF MBR Water Treatment Water Treatment Equipment Membrane System

Membrane Bioreactor (MBR) is a kind of advanced technology developed since the end of 20th century which realized the efficient combination of membrane separation technology with biological technology. The membrane separation technology replaces the traditional active sludge method and the normal filter unit, its strong separation ability can make the SS turbidity near to be zero. Hydraulic retention time (HRT) sludge age (SRT) is completely separated, the outlet water is good and stable in quality, it can be reused without the third level treatment. Due to the high security and economic and effective water, it greatly expands the scope of application of waste water recycling.

Advantages

Easy to clean;High efficiency / Low maintenance;Membrane modules are back flushable;Yield 60-80% less sludge than conventional system;Compact design – footprint 75% smaller than conventional;Possibility of direct and indirect water reuse.

1. Advanced Material: The main material of the membrane is PVDF, which has Excellent chemical stability, permeate flux, permeate quality,
and fouling resistance.
2. Better outlet water quality:Pore size of Rosun flat sheet membrane is around 0.1 micron, and with advanced membrane technology increased the effective orifice area of the membrane surface then lead to excellent permeate flux and permeate quality. The output water can be reused directly.
3. Higher activated sludge adaption:Compared with the hollow fiber curtain membrane whose activated sludge adaption is only 4000-
6000mg/l,Rosun flat sheet membrane can adapt 8000-15000mg/L activated sludge, which made our flat sheet membrane specially suitable for industrial waste water, hospital waste water, Landfill leachate,lectroplating waste water, and refractory organic wastewater.
4. Longer service life:Compared with hollow fiber curtain membrane,Rosun flat sheet membrane will not have break, twine and clay lump
problem when use.which made our flat sheet have a longer service life 3-6years compared with 1-3years service life of hollow fiber curtain
membrane’s.
5. Less land space:The MBR reactor tank can replace the function of secondary sedimentation tank with aerobic tank,it can save 30% of land space. With high concentration of microorganisms, it have high volumetric loading, and it has simple technical process and compact
structure, suitable both for ground and half underground design.
6. Easy to Operate and maintenance:The flat sheet membrane can be just replaced each single damaged piece without change the holder when damage and replacement, replace just need 15 minutes,it realized the complete separation of hydraulic retention time (HRT) and sludge retention time (SRT), making operation and control more flexible and stable.
7. Economy:The cleaning cycle of flat sheet membrane is more than 3months which is longer than the 1 month cleaning cycle of hollow fiber curtain membrane’s. And it is no need to back-wash, therefore, it will save manual, chemical and electricity cost. When close to the
membrane service life, the Hollow fiber curtain membrane cannot use any more, but for flat sheet membrane just need to replace 1/3~1/2, the outlet water quality can still reach the requirement.
