WEBOct 1, 2013 · Plants operating within an extended-aeration range are usually small and without 24-hour-per-day operator attendance. They ordinarily operate within a mean cell residence time (MCRT) in a range of 20-40 days and a food/microorganism (F/M) ratio between 0.05-0.15 lbs. MCRT is the average time a microorganism will spend in the activated sludge ...
The basics of activated carbon adsorption | Water Technology
WEBFeb 1, 2016 · Activated carbon removes water soluble organics and solids from water by backwashing. This MTZ has three working zones: Zone 1 (between A and B, a portion of the total length of the carbon bed) is completely used and no longer removes water-soluble contaminants. Zone 2 (between B and C) removes variable amounts of contaminants.
