Municipal wastewater was treated at hydraulic retention times from 15 to 70 min and internal circulation capacity of 20, 40 and 60 drn':h'. Depending on hydraulic retention time, the sludge yield ranged from 0.138 to 0.066 g TSS·g COD·' in reactor I and from 0.175 to 0.107 g TSS·g COD·' in reactor li. An increase in volumetric loading rate and internal circulation capacity caused a reduction in sludge yield. A decrease in the sludge yield corresponded to an increase in the ratio of endogenous to substrate respiration by the immobilized biomass}, type={Article}, title={Biomass Yield in Porous Ceramic Carriers for Municipal Wastewater Treatment}, URL={http://journals.pan.pl/Content/122833/PDF-MASTER/4_AE_VOL_36_3_2010_Zielinska_Biomass.pdf}, keywords={Immobilization of activated sludge, wastewater treatment, biomass yield}, }
