MBR(Membrane bioreactor) is submerged flat sheet module which effectively removes suspended particles. MBR module consist a number of membrane elements stacked at equal intervals. Each element has flat sheet membranes on both sides of a supporting panel.
Using membranes to separate sludge ensures much higher quality for treated water free from suspended solids
MBR can retain activated sludge at high concentration, allowing BOD as well as nitrogen to be removed more efficiently.
Unique membrane configuration having an immense number of minuscule pores delivers stable high water permeability with minimal clogging and higher permeated water quality.
The module can be submerged directly in a activated sludge tank for combining biological treatment and membranes separation. It eliminates the sedimentation or sludge concentration process.
More effective biological treatment allows activate sludge tank size to be reduced.
The plate and frame configuration that employs flat sheet membranes is inherently stronger against fouling than hollow fiber membrane configuration. Therefore, it results in fewer chemical cleaning requirements.
It consumes less energy compared to hollow fiber membrane due to more effective scouring aeration and lower trans-membrane pressure.
Using PVDF (polyvinylidene fluoride) for the functional layer of the membrane and non-woven base layer allows the membrane to exhibit superior physical strength and chemical stability.
