What describes the typical operation of a flow equalization basin?

The typical operation of a flow equalization basin is best described by its function of filling during peak hour flows and emptying during low flows. This approach is fundamental in wastewater treatment as it helps manage variations in flow rates. During periods of high inflow, the basin captures and stores excess water, preventing overloading of downstream treatment processes. Conversely, during times of low flows, the stored water is gradually released to maintain consistent flow to the treatment plant. This process helps to stabilize treatment operations, ensuring that the treatment plant can function more efficiently and effectively under varying conditions. By mitigating the impact of sudden flow fluctuations, flow equalization basins play a crucial role in protecting the treatment facility from operational surges and maintaining consistent treatment performance.
