WebSRT — solids retention time — is sometimes used as a synonym for MCRT. They typically mean the same thing, but they may be calculated using different pieces of data. SRT can … Webfor wastewater to pass through a tank, such as an aeration tank. Changes in the HRT of an activated sludge process can a¤ect bio-logical activity. For example, decreasing HRT … WebSolids Retention Time (SRT) sets the growth rate of microorganisms in an activated sludge process, thereby selecting the microbial composition of the mixed liquor. For consistent wastewater treatment, SRT must be controlled at a level that oxidizes pollutants, e.g. nitrifies, while providing "bugs" that flocculate and settle. clwyd alyn women\\u0027s aid
