Both types of biomass, despite some similarities, show also many differences. Probably as a result of complex relations (competition, migration, physical factors like flow velocity and biochemical factors like oxygen supply) the flocs and attached biomass can demonstrate many differences, e.g. texture, active surface, heterotrophs and autotrophs ratio, and especially biomass age. A compilation ...

RESUMO Neste trabalho, avaliou-se o uso do modelo matemático ASM3 para um sistema piloto de reator compartimentado anaeróbio/anóxico e aeróbio tipo MBBR, utilizado a remoção simultânea matéria orgânica nitrogênio em esgoto doméstico. A simulação computacional foi implementada pelo software ASIM. Selecionou-se conjunto padrão parâmetros modelo, com uma combinação dos valores calibrados dados da ...

Moving bed biofilm reactors (MBBRs) were placed at two wastewater treatment plants, where they constantly fed with effluent and intermittently primary wastewater. Each reactor was subjected to different feast/famine periods flow rates of wastewater, thus the organic nutrient loads (chemical oxygen demand(COD), ammonium(NH4-N)) resulted in feast-famine conditions applied biomass. In batch experi...
