Web6 jan. 2024 · The HRAS process relies on the high food-to-microorganism (F/M) ratios and low solid retention times (SRTs) and hydraulic retention times (HRTs), resulting in the minimization of organic matter mineralization and the maximization of its diversion to the sludge via sorption and intracellular storage as opposed to conventional activated sludge … Web10 mei 2024 · When treating actual wastewater, interference of low temperature and components in the influent is another problem. Relatively high activity of anammox bacteria has been realized after artificial acclimation at low temperature and the mechanism was also preliminary explored.
Websludge systems operated at comparably low solid retention time, SRT (Ge et al., 2015). By operating the activated sludge process at relative low SRT wastewater resources can be separated and recovered, rather than destroyed. The main objectives of the present study are i) to describe the reactor start-up operation conditions for a low-SRT enhanced Web1 apr. 2016 · The SRT is controlled by means of the sludge-wasting rate. For example, in the case of an activated-sludge system that has an inventory of 60 tons of sludge solids, and the total wasting rate is 2 tons of sludge solids per day, the SRT amounts to 60/2 = 30 days.
