The length of time it takes for the water on top to leave the tank is the hydraulic retention time of that tank. Eventually, the water on top of the settled particles will move to another tank in the wastewater management process, allowing more wastewater to take its place. Sedimentation is the process of waste matter in the water settling to the bottom of the tank. Wastewater enters a confined tank, which allows sedimentation to occur. Here’s one way to picture hydraulic retention time. This process goes by other names, including hydraulic residence time, and has a huge impact on effluent water quality. At its simplest definition, HRT is the average amount of time a gallon of wastewater will remain in a particular basin during the wastewater treatment process.įor a more technical definition, think of HRT as the measure of a soluble compound’s average time remaining in a constructed biogas reactor or aeration tank. Note that hydraulic retention time is also different than solid retention time. It is crucial to understand the importance of HRT and how it relates to facility processes.

Good effluent water quality is safe for rerelease into nature, but how does wastewater get to that point? Many biological treatment processes come into play, including the activated sludge process and anaerobic digestion. Only after receiving treatment at a wastewater facility can this water be introduced back into the environment in a safe manner. Cities with high populations and industries that generate large amounts of wastewater can harm the environment without properly treating the wastewater they produce. Wastewater treatment facilities are an essential part of communities and businesses around the world.
