A sequencing batch reactors are used for water treatment. Oxygen is fizzed through sewage water and activated sludge in batches which in turn reduces organic matter in the sewage water.
SBR sewage treatment includes five treatment stages, fill, react, settle, decant and idle.
A certain amount of sewage water is first filtered to remove larger unwanted particles. Then oxygen is bubbled through the wastewater to ensure oxygen supply is sufficient as it is necessary for the aerobic biochemical process. Microorganisms use the oxygen supplied to ingest organic matter that was not filtered. This mixture is then allowed to rest. The sludge settled at the bottom is mostly the microorganisms that have consumed the organic matter and the effluent is removed. Most of these microorganisms are then removed from the reactor. Since some of the microorganisms are left behind, they quickly populate before the next batch of sewage water is sent in for treatment.
SBR sewage treatment plants are used to treat both industrial wastewater as well as municipal wastewater. To learn about the benefits of SBR sewage water treatment, read ahead.
Gains of Having an SBR Sewage Treatment Plant
It is cheaper than most biological treatments available in India
2. Space Reduction
SBR is comparably a small sewage treatment plant when compared to other wastewater treatment plants. It requires very little space when compared to other treatment plants.
Effluent that gets separated from the sludge is of high quality. It has fewer pollutants such as ammonia and phosphates which are reduced by 96% and 88% respectively.
SBR does not have a lot of movement as it does not have any moving elements. Most functions are run by air control and does not require a lot of space. Since it operates through batches, each batch is thoroughly rid of waste and treated completely. As every action occurs in a single tank, the process becomes simple. The SBR system is flexible and its tank is versatile.
An SBR reduces both the mechanical and manual resources used. Since it uses one tank which does all three tasks, equalize, aerate and clarify the water, it does not require separate tanks for each of these. Therefore, reduces the resources required. It is mostly automated and hence, does not require supervision. Therefore, it reduces staff requirements.
6. Power Consumption
Sewage treatment plants in India generally absorb and require a lot of power consumption. With electricity outrage, running a sewage water treatment plant that requires a lot of power becomes impossible. The power consumption of an SBR sewage water treatment plant is comparably lower as it has greater turndown capability.
