MBR system is a progression of the company’s proven sewage treatment technology for handling grey and black waste water. Membranes act as a barrier to bacteria and suspended solids to produce a low turbidity treatment plant effluent with very low bacteria counts. MBR is the combination of a membrane process like microfiltration or ultra-filtration with a suspended growth bioreactor. This very compact arrangement produces a MF/UF quality effluent suitable for reuse applications or as a high quality feed water source for Reverse Osmosis treatment. The MBR process can be employed in activated sludge processes, using the membranes as liquid-solid separation instead of the usual settling. It has high separation property due to trans-membrane pressure, blocks sludge & large molecules in the membrane letting clear water to permeate through.
MBR PROCESS:-
Pre-Treatment
Pre-Screen
Oil & grease removal
Sand removal & fine screen
Bio Reactor
Submerged membrane/Airlift membrane
Air blowers diffuse air to the wastewater
Balance sludge discharge through pump
Clear water will be permeated out by self-priming pump at vacuum pressure through MBR Modules
The Sequencing Batch Reactor (SBR) is an activated sludge process working in a batch mode with aeration and sludge settlement both occurring in the same tank. This leads to a reduction in civil costs and less space is required as several steps are occurring in the same tank there are five stages in the treatment process
1. Fill
2. React
3. Settle
4. Decant/Draw
5. Idle
The inlet valve opens and the tank is being filled in, while mixing is provided by mechanical means (no air). This stage is also called the anoxic stage. Aeration of the mixed liquor is performed during the second stage by the use of fixed mechanical pumps or by transferring air into fine bubble diffusers fixed to the floor of the tank. No aeration or mixing is provided in the third stage and the settling of suspended solids starts. During the fourth stage the outlet valve opens and the "clean" supernatant liquor exits the tank.
