SBR , MBR System

SBR is an activated sludge process designed to operate as a batch process instead of a continuous process. Here aeration and sludge settlement occur in the same tank. The SBR design is a fill-and-draw type activated sludge process where the following steps take place consecutively i.e. anoxic fill, reaction, settling, decanting followed by sludge wastage. The SBR aeration system generally consists of fine bubble air diffusers. In this process, the compressed air is sheared in to small bubbles creating large specific surface area for high mass transfer efficiency between air and wastewater. SBRs produce sludge with moderate settling properties provided the influent wastewater is admitted in to the aeration in a controlled manner. The SBR process is fully automated to control the operation of the various cells.
Filling, aeration and settling is done by PLC based timer operation. The settled effluent is decanted using a decanter mechanism. Sludge is withdrawn and recycled to the tank inlet for maintaining required MLSS and anoxic conditions. Excess sludge is dewatered in a thickener followed by filter press and then disposed.

Advantages of SBR

Excellent treated Effluent quality in terms of BOD, TSS & nutrient removal
Partial removal of colour.
Less footprint area required as compared with extended aeration as no secondary clarifiers.
Better Coliform removal efficiency hence lower disinfection requirements.

MBR

The MBR technology is a relatively recent development in the field of biological treatment, using a membrane based process to produce clear treated wastewater with low turbidity, suitable for RO feed. Membranes are placed in the aeration tank to separate treated effluent from mixed liquor. Membranes being an absolute physical barrier ensure removal of suspended and colloidal impurities. MBR applications include retrofits of existing systems as well as installation of new systems, for both meeting the most stringent discharge norms and also for reuse. The MBR process operates at higher MLSS concentration with higher sludge retention time thus producing a low quantum of biological sludge and therefore reducing the sludge dewatering cost. In the MBR process, the liquid solids separation takes place using membranes. The product is a clear, low- turbidity effluent and no secondary clarifier is required in this process.

Advantages of MBR

Excellent treated Effluent quality in terms of BOD, TSS & nutrient removal
Partial removal of colour
Effluent is treated through inbuilt UF and hence good in applications where post treatment is RO
Secondary clarifier not required
Less foot print required
