Avaliou-se o efeito das águas residuárias de suinocultura com concentrações de sólidos suspensos totais em torno de 6.000 mg L-1 (DQOtotal variando de 7.557 a 11.640 mg L-1) no desempenho de processo anaeróbio em dois estágios compostos por reator compartimentado (ABR) e reator de fluxo ascendente com manta de lodo (UASB), instalados em série, em escala-piloto (volumes de 530 e 120 L, respectivamente),

In this work it was evaluated the effect of swine wastewater with total suspended solid (TSS) concentration around 6000 mg L-1 (CODtotal from 7557 to 11640 mg L-1) on the performance of two stage anaerobic process constituted of anaerobic baffled reactors (ABR) and an upflow sludge blanket reactor (UASB) installed in series, in pilot scale testing (volumes of 530 L and 120 L, respectively) and with hydraulic detention times (HDT) of 56 to 18 h in the first reactor and 13 to 4 h in the second reactor.

The shut-off valve is actuated by an electric solenoid. For added assurance, two solenoids are installed in series between the primary and secondary regulators. Factory Mutual (FM), Underwriter’s Laboratory (UL), and all other governing codes and utility requirements should be consulted for specific gas train requirements.
