The Batch Process (SBR) works through a series of steps, including:
- Aeration: Wastewater is pumped into an aeration tank where it is mixed with air and inoculated with bacteria. This promotes the oxidation of organic matter and the elimination of carbon dioxide.
- Settling: The water is then transferred to a settling tank where the suspended solids settle to the bottom.
- Decantation: The water is transferred to a decantation tank where the liquid part is separated from the solid part.
- Secondary biological treatment: The water is transferred to a secondary biological treatment tank where it undergoes additional biological treatment to remove remaining pollutants.
At the end of the process, the treated water is released into the environment or reused, depending on local regulations and industry specifications.
The Batch Process (SBR) offers several benefits, including:
- Flexibility: The SBR process is highly flexible and can be adapted to handle a variety of types and levels of pollution.
- Efficiency: The SBR process is highly efficient at removing pollutants, especially nitrogen and phosphorus.
- Low Cost: The SBR process is generally regarded as a low cost wastewater treatment method.
- Low maintenance: The SBR process requires little maintenance and is easy to operate.
- Water reuse: The SBR process is capable of producing high quality treated water, which makes it possible to reuse it in various applications, including irrigation, industrial use and domestic use.
- Odor Control: The SBR process can be designed to control odors, which is important in industrial wastewater treatment applications.
- Space Taken: The SBR process requires less space compared to other wastewater treatment processes due to its high efficiency and ability to treat large volumes of wastewater in smaller tanks.
The Batch Process (SBR) is widely used in various applications, including:
- Domestic Wastewater Treatment: The SBR process is commonly used to treat domestic wastewater in small communities and suburbs.
- Industrial Wastewater Treatment: The SBR process is widely used to treat industrial wastewater from various industries including food, paper, textile, chemical and pharmaceutical.
- Sewage Wastewater Treatment: The SBR process is used in sewage treatment plants to remove pollutants before releasing the treated water into rivers or oceans.
- Water reuse: The SBR process is used to treat and purify water for reuse in various applications, including irrigation, industrial use and domestic use.
- Farm Wastewater Treatment: The SBR process is used to treat farm wastewater, including manure and animal bath water.
- Mining Wastewater Treatment: The SBR process is used to treat mining wastewater, including ore wash water and mine drainage water.
