One advantage of this orientation is flexibility of operation. The total time in the SBR is used to establish the size of system and can be related to the total volume of a conventional continuous-flow facility. As a result, the fraction of time devoted to a specific function in SBR is equivalent to some corresponding tank in a space oriented system. Therefore the relative tank volumes dedicated to , say aeration and sedimentation in the SBR can redistributed easily by adjusting the mechanism which controls the time ( and , therefore share the total volume) planned for either function. In conventional ASP, the relative tank volume is fixed and cannot be shared or redistributed as easily as in SBR.

• Single tank for reaction and settling.
• True batch mode of operation & can be operated as a time-based control system allowing continuous inflowof wastewater during all phases of the cycle.
• Ability to achieve biological oxidation, nitrification, de-nitrification, phosphorus removal and solid/liquidseparation.
• Computer interface technologies, and advanced monitoring instrumentation capability, and ability to beoperated remotely.
• Less labour required when operated automatically and computer controlled.

It is proposed to use Membrane Bio-Reactor (MBR) system working on the principle of filtration of activated sludge through the concept of using flat sheet type or hollow fibre type submerged membrane modules in bioreactors. The membranes in a MBR system are made from polymeric organics (PVDF, PE or PES) and assembled into units (modules, cassettes, stacks) with high packing density. Raw wastewater pre-treatment is important to sustain stable MBR performance and fine screening is essential operation.

• MBR is capable of meeting the most stringent effluent water quality standards.
• Membrane modules are back-flushable
• Yield 60-80% less sludge than conventional system
• Requires cleaning only once in 3 to 6 months.
• Maintain high MLSS
• No secondary clarifier, virtually no effluent suspended solids, no RAS recycling.
• It allows systems to be remotely operated and monitored, thus significantly reducing operator attendance.
• Sludge can be wasted directly from aeration tank
