WebbSolids 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.
