Two different porous ceramic carriers with immobilized activated sludge comprised a stationary filling of the reactors. Municipal wastewater was treated at hydraulic retention times from 15 to 70 min and internal circulation capacity of 20, 40 and 60 dm3.h-1. Depending on hydraulic retention time, the sludge yield ranged from 0.138 to 0.066 g TSS.g COD-1 in reactor I and from 0.175 to 0.107 g TSS.g COD-1 in reactor II. 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.

Przyrost biomasy w porowatych nośnikach ceramicznych podczas oczyszczania ścieków komunalnych Dwa porowate nośniki ceramiczne z unieruchomionym osadem czynnym stanowiły stacjonarne wypełnienie bioreaktorów, w których oczyszczaniu poddawano ścieki komunalne przy hydraulicznym czasie zatrzymania od 15 do 70 min i cyrkulacji wewnętrznej równej 20, 40 i 60 dm3.h-1. W zależności od hydraulicznego czasu zatrzymania, współczynnik przyrostu biomasy zmieniał się z 0,138 do 0,066 g TSS.g COD-1 w reaktorze I oraz z 0,175 do 0,107 g TSS.g COD-1 w reaktorze II. Zwiększenie obciążenia objętości reaktorów ładunkiem zanieczyszczeń oraz wydajności cyrkulacji wewnętrznej powodowało zmniejszenie przyrostu biomasy. Spadek przyrostu biomasy odpowiadał wzrostowi stosunku oddychania endogennego i substratowego unieruchomionej biomasy.
