Re-commissioning your dead STP plant with the help of EM culture

Sewage Treatment Plants (STPs) are crucial for treating wastewater and ensuring that it does not harm the environment. However, STPs can sometimes fail due to a lack of proper maintenance, aging equipment, or other reasons. In such cases, it is possible to re-commission the STP using effective microbial cultures, such as Effective Microorganisms (EM).

EM is a unique culture of naturally occurring beneficial microorganisms that can help restore the microbial balance in the wastewater treatment process. This blog will provide a step-by-step guide to re-commissioning your dead STP plant with the help of EM culture.

Step 1: Inspection and Assessment

The first step is to assess the extent of damage to the STP and determine the causes of failure. This involves a thorough inspection of the equipment and infrastructure, such as pipes, pumps, filters, and tanks. It is essential to identify any blockages or leaks that may be impeding the treatment process. A professional consultant can help in conducting this assessment and recommend the appropriate remedial measures.

Step 2: Flushing the System

Once the inspection and assessment are complete, it is time to flush the STP system. This involves removing any residual water and solids from the system to ensure that it is clean and ready for re-commissioning. It is essential to wear protective gear, such as gloves and masks, during this process to avoid exposure to harmful pathogens.

Step 3: Inoculation with EM Culture

After flushing, the STP is inoculated with EM culture. EM culture contains beneficial microorganisms that help in breaking down the organic matter in wastewater and restoring the microbial balance. The culture is typically mixed with water and introduced into the STP in a controlled manner. The quantity of EM culture to be used depends on the size and capacity of the STP, as well as the specific conditions of the wastewater.

Step 4: Monitoring and Maintenance

After inoculation with EM culture, the STP needs to be closely monitored to ensure that the treatment process is progressing as expected. This involves regular testing of the wastewater to measure its pH, BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), and other parameters. Any issues or deviations from the expected results should be addressed immediately.

Regular maintenance of the STP is also critical to ensure its efficient functioning. This involves routine cleaning of tanks, filters, and pipes, as well as periodic replacement of parts that have reached the end of their life.

Conclusion

Re-commissioning a dead STP plant using EM culture can be an effective way to restore its functionality and treat wastewater effectively. The process involves a thorough inspection and assessment, flushing the system, inoculating with EM culture, and regular monitoring and maintenance. It is essential to engage with professional consultants who have experience in the re-commissioning process to ensure that it is done effectively and in compliance with local regulations. With proper re-commissioning and ongoing maintenance, your STP can continue to operate efficiently and protect the environment.
