Flow equalization is used to:

Flow equalization is used to:

• A. Increase treatment capacity by removing solids
• B. Reduce peak flow variations into the plant
• C. Disinfect the effluent
• D. Aerate the wastewater

Answer: (B)

Flow equalization centers on smoothing out large, rapid changes in wastewater flow entering the plant. By storing excess flow during high-flow periods and releasing it during lower-demand times, it creates a steadier, more manageable influent. This helps protect downstream processes, maintain stable detention times, and prevent process shock from sudden surges. It doesn’t remove solids, disinfect, or aerate the wastewater, so those functions aren’t the purpose of flow equalization.
