SBR Technology in Sewage Treatment Plant

SBR is a high-performance solution for wastewater treatment that can successfully handle batch and continuous flow operations. It is a proven technology with minimal costs and maintenance requirements. Due to high removal capacity and versatility, it is compliant with stringent discharge standards. Biological process and high-quality product generation are the distinct qualities of SBR based sewage treatment plant.

Due to its streamlined design, R&J WASTE WATER TREATMENT ORGANIZATION SBR small Sewage Treatment Plant is one of the most favored wastewater treatment systems today. This highly flexible technology is useful in a wide variety of applications.

What is SBR-Based Sewage Treatment?

SBR process has been a widely used water treatment method in developed countries for quite a long time. It has become popular in India, China, and other Asian countries in recent years. When sewage is sent to the SBR Tank (also known as the Reaction tank) one batch at a time, an activated sludge process gets activated. A timed sequence of operations occurs in the SBR tank and water gets purified. Here is the timed sequence of events:

• Filling
  It is the first stage of the process where the influent wastewater is filled in the first tank. It is important that the water gets filled with a controlled yet rapid flow so that the Food to Microorganism Ratio remains appropriate. It is similar to the selector mechanism which ensures sufficient growth of microorganisms that have better settling characteristics.
• Aeration
  In the reaction stage, microorganisms use Ammonia, Nitrogen, or BOD (Biochemical Oxygen Demand). The degree of treatment is directly proportional to the sludge mass and the time taken for aeration. It also depends on the strength of the wastewater (or the level of impurities) and the degree of nitrification. It is the rate of conversion of Ammonia into nitrate or nitrite of less toxicity.
• Settling
  Settling takes around 60 minutes to 90 minutes depending on the number of cycles per day. In this process, aeration stops and sludge gets settled. Cleat, effluent water gets accumulated over the sludge blanket.
• Decanting
  Decanting is the process of removing the effluent from the tank without disturbing the sludge settled at the bottom.
• Idling
  Idling is the waiting time between two filling cycles.
• Sludge Wasting
  When sludge gets accumulated beyond a threshold level, it has to be discharged from the system. The sludge wasting process controls the quality of effluent water and the population of microorganisms. Two parameters are adjusted to keep better control over the quality of sludge waste.

✦ Mixed liquor suspended solids (MLSS)
✦ Mean cell residence time (MCRT)

SBR Tank acts as the aeration tank in the reaction stage when activated sludge and influent water are mixed under aerated conditions. It also works as the secondary clarifier during two stages; the settling stage and the decanting stage. Mixed liquor is again allowed to settle, and the overflow moves to the next stage of treatment. In the Sludge Return System, after settling in the SBR tank, the influent gets mixed with the sludge return system again. However, in this case, the feed is transferred to the sludge and not vice-versa.

Benefits of SBR in STPs:

• Compact Design: As all treatment steps occur in one tank, SBR systems require less space, making them suitable for urban or space-constrained areas.
• Flexible Operation: Ideal for handling varying sewage flows and loads, as the system can adapt the timing and duration of each phase.
• High Treatment Efficiency: SBR technology effectively removes organic matter, nitrogen, and phosphorus, resulting in high-quality treated water suitable for discharge or reuse.
• Automation: SBR systems can be highly automated, allowing precise control over each phase, and reducing operational labor.

Usage and Application

SBR-based sewage treatment plant is ideal for several applications:

It is the most suitable system for heavy loads of industrial or municipal wastewater. The SBR process is ideal for both cold and warm climates.
A streamlined design keeps equipment and operating costs optimized.
It can be upgraded easily in a cost-effective manner.
Meets the 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.
Qualities That Stand Apart SBR Sewage Treatment Plant From Others
It is highly operator-friendly due to maximum automation and minimum human intervention. Due to PLC based monitoring and control system, it is an advanced and smart system.
The system is flexible by supporting continuous feed as well as true batch operations flow control strategies.
It is resilient to extraneous water infiltrations. Hence, it is ideal for wastewater collection networks. It is capable of handling organic as well as hydraulic variations.
Meets effluent discharge limits consistently.
It is more advantageous than other systems as far as the initial capital investment versus operational cost is concerned. Thus, it offers the best life cycle.

Application and Usability

Due to high versatility and cost-effectiveness, the SBR sewage treatment plant is widely used in:

• Personal bungalows, houses, and weekend homes
• Hotels, resorts and holiday homes
• Hospitals
• Malls and shopping centers
• Airports and railway stations
• Commercial and residential complexes
• Project sites
• Schools, colleges, and other institutions
• Small, medium, and large manufacturing units
• Municipal Gardens
• Sports complexes
• Other public places
