Abstracts

This study evaluated the treatment of wastewater from coffee wet processing (WCWP) in an anaerobic treatment system at a laboratory scale. The system included an acidification/equalization tank (AET), a heat exchanger, an Upflow Anaerobic Sludge Blanket Reactor (UASB), a gas equalization device and a gas meter. The minimum and maximum flow rates and volumetric organic loadings rate (VOLR) were 0.004 to 0.037 m³ d-1 and 0.14 to 20.29 kgCOD m-3 d-1, respectively. The kinetic parameters measured during the anaerobic biodegradation of the WCWP, with a minimal concentration of phenolic compounds of 50 mg L-1, were: Y = 0.37 mgTVS (mgCODremoved)-1, Kd = 0.0075 d-1, Ks = 1.504mg L-1, µmax = 0.2 d-1. The profile of sludge in the reactor showed total solids (TS) values from 22,296 to 55,895 mg L-1 and TVS 11,853 to 41,509 mg L-1, demonstrating a gradual increase of biomass in the reactor during the treatment, even in the presence of phenolic compounds in the concentration already mentioned.

O presente estudo avaliou o tratamento das águas residuárias do processamento por via úmida do café (ARC) em sistema de tratamento anaeróbio em escala de laboratório. O sistema utilizado foi composto de um tanque de acidificação e equalização (TAE), um trocador de calor, um reator anaeróbio de manta de lodo e fluxo ascendente (UASB), um equalizador de pressão e um gasômetro. Os valores de vazão mínimos e máximos foram: 0,004 a 0,037 m³ d-1 e os valores da carga orgânica volumétrica (COV) foram 0,14 a 20,29 kgCOD m-3 d-1, respectivamente. Os parâmetros cinéticos encontrados durante a biodegradação anaeróbia da ARC com concentração mínima de compostos fenólicos de 50 mg L-1, foram: Y = 0,37 mgSTV (mgCODremoved)-1; Kd= 0,0075 d-1; Ks = 1.504 mg L-1 e µmax = 0,2 d-1. O perfil de lodo no reator apresentou valores ST de 22.296 a 55.895 mg L-1 e de STV de 11.853 a 41.509 mg L-1, demonstrando o crescimento gradativo da biomassa no reator durante o tratamento, mesmo na presença de compostos fenólicos na concentração anteriormente mencionada.
