摘要:Production of a methane-rich gas (‘biogas’) is contemporary popular sludges processingtechnology which allows to generate thermal and/or electrical energy.Formal requirements issuedby the European Union to promote so called renewable energy resources mad these process moreattractive leading to its application in WWTPs which were designed based on different sludges handlingprocesses.Authors (as active design engineers) noted that dimensioning of sludge digestionchamber is usually based on SRT assessment without any emphasis on sludges characteristics.Biomass‘ characteristics and estimation of its activity with respect to methane production are of greatimportance both from scientific and practical points of view, as anaerobic digestion appears to beone of crucial processes in municipal wastewater handling and disposal.Authors propose respirometrictests to estimate a biomass potential to produce ‘a biogas’ and several years’ laboratory andfull scale experience proved its usefulness and reliability both as a measurement and a design toolapplicable in sludge handling.Dimensioning method proposed by authors, allows to construct andoptimize operation of digestion chambers based on a methanogenic activity.
