What should an industrial facility do if it plans to discharge a high concentration BOD waste into the wastewater plant?

Requiring pretreatment by the industrial facility is crucial when a facility plans to discharge wastewater with a high concentration of biochemical oxygen demand (BOD). High BOD levels can significantly overload the municipal wastewater treatment plant, leading to inefficiencies in the treatment process, potential permit violations, and detrimental impacts on the receiving water bodies.

Pretreatment involves the industrial facility reducing the BOD of its waste prior to discharge through various methods such as physical, chemical, or biological processes. This step helps ensure that the incoming wastewater remains within the treatment plant's operational limits, allowing the facility to effectively manage and treat the collected waste. It is a vital step in maintaining the overall health of the municipal wastewater system and protecting the environment.

While increasing treatment plant capacity, discharging during off-peak hours, or utilizing a secondary treatment process may appear to address the issue, they do not tackle the problem at its source. Pretreatment is a proactive measure that prevents complications before the wastewater even enters the treatment facility.
