What is the primary purpose of the sluice gate in sewage treatment?

The primary purpose of the sluice gate in sewage treatment is to control the flow of sewage. Sluice gates are devices that can be opened or closed to manage the volume and rate of liquid passing through a treatment facility. By adjusting the position of the gate, operators can efficiently regulate flow rates based on treatment processes, ensure proper detention times in various treatment stages, and prevent overloading of treatment units. This flow control is essential to maintain optimal treatment conditions, ensuring that sewage is adequately treated before being discharged or further processed.

While temperature regulation, sludge concentration measurement, and aerating wastewater are important aspects of sewage treatment, they are not the primary functions of sluice gates. Instead, those tasks are typically handled by other equipment designed specifically for those purposes.
