Abstract : Advantages of anaerobic fixed film reactors over other biological treatment units are: (1) No limits set on influent soluble organics concentration. (2) No limits set on organic loads applied. (3) The lowest sludge (biomass) yield of all available bioreactors. (4) The lowest N&P requirements. (5) The availability of optional operation in plug-flow and completely mixed mode through recycle. (6) The lowest level of attention required and associated low operating costs. (7) Feasibility of seasonal, 5 days/week or otherwise intermittent operation. (8) Highest resistance to toxic and inhibitory compounds. (9) Low area (real estate) requirements. (10) Odorless operation. (11) Generation of high CH4-concentration (above 70%) gas.
