It is the best suitable system for heavy loads of industrial or municipal wastewater. SBR process is ideal for both cold and warm climates. Streamlined design keeps equipment and operating costs optimized. It can be upgraded easily in a cost-effective manner. Meets requirement of cleaning effluents without getting affected by prevalent conditions. Around 98 percent removal of TSS and BOD, reduction of Phosphorus and Nitrogen in one step.

In order to meet more stringent reuse requirement, which is beyond what can be accomplished by conventional sewage treatment plant; a tertiary treatment (filtration) are incorporated when requested, to further polish the secondary treated water.

The membrane bioreactor facility consists of aerobic tank and anoxic tank. Membrane modules are immersed inside the aerobic tank where organic contents (BOD) in the sewage will be biologically degraded by activated sludge. The MLSS (Mixed Liquor Suspended Solid) concentration in the MBR System is 10 to 20 g/L compared to 3 to 4 g/L in conventional activated sludge systems, thus the retention time required is only 30% of conventional system. The membranes also separate suspended solids from liquid through the filtration process. As the pore size of the membrane is 0.1 micron, not only suspended solids but also bacteria such as coliform bacteria are also removed. The immersed membrane filtration process also eliminates the requirement for gravity sedimentation tank or clarifier required by conventional activated sludge systems. Through recirculation of MLSS from aerobic tank to anoxic tank, nitrate content is removed. Additional coagulant and flocculant dosing also can be incorporated for phosphorous removal.
