Measurement of active biomass in activated sludge mixed liquor
… sludge systems is the parameter heterotrophic active biomass (X8 u, mgAVSS/l as measured per the VSS test, or Zm-r, mgCOD/l as measured per the COD test). This mixed liquor organic suspended solids component mediates the biodegradation processes of COD removal and denitrification (and …

Evaluation of batch test for measurement of active biomass in activated sludge mixed liquor
Over the past two decades significant advances have been made in the areas of engineering (design) and technology (implementation and operation) of the single sludge activated sludge system. Activated sludge systems have been successfully designed and implemented at full-scale for the biological …

Batch test for measurement of ordinary heterotrophic organism active biomass in activated sludge mixed liquor
To aid the design and operation of the single sludge activated sludge system, over the past three decades a suite of steady state design models (e.g. WRC, 1984; Wentzel et al., 1990; Maurer and Gujer, 1994) and kinetic simulation models (e.g. Dold et al., 1980, 1991; Van Haandel et al., 1981; Henze …

Characterization of municipal waste waters
… biodegradable, unbiodegradable and heterotrophic active biomass. The unbiodegradable COD is subdivided into particulate and soluble fractions based on whether the material will settle out in the settling tank (unbiodegradable particulate) or not (unbiodegradable soluble). The biodegradable …

Development of a new high-rate anaerobic process for the treatment of industrial and domestic wastewaters: the anaerobic migrating blanket reactor (AMBR)
… mechanical mixing to obtain a sufficient biomass/substrate contact. The formation of granular biomass was not dependent on a hydraulic upflow pattern in the reactor, but was dependent on biomass migration over the horizontal plane of the reactor and the settling characteristics of the …

Investigating human pharmaceutical compounds present in municipal and hospital wastewaters and options for their removal
… The MWWTPs that utilized long aeration and biomass retention times (HRT,SRT), as evidenced by the occurrence of complete nitrification, were more efficient at removing paracetamol, naproxen, bezafibrate and atenolol, than the non-nitrifying plants with relatively shorter HRT and SRT. HWWTPs …
