DETERMINATION OF DESIGN CRITERIA OF AN H-IFAS

The activated sludge process is a suspended culture system that has been in use since the early 1900 s. The process derives its name from the fact that settled sludge containing living, or active, microorganisms is returned to the reactor to increase the available biomass and speed up the reactions. It may be either a completely mixed or plug

Analysis of Energy Consumption and Saving in Wastewater

indirect power consumption is the sum of that devoted to THP/digestion system plus the dryers or 2.05 MWh/tDS (0.15 + 1.90) MWh, i.e. 116,850 MWh/yr. Typically the anaerobic digestion consumes approximately 14.2% with dyers says 20% of the total power consumption. The direct power consumption will be the remaining 80%, i.e. 467,400 MWh/yr.
