the evaluation of treatment characteristics and sludge properties of an upflow anaerobic sludge blanket (uasb) process was investigated using a pilot-scale 1.15 m3reactor. the uasb, inoculated with digester sludge, was operated at a hydraulic retention time of 8 h at sewage temperatures ranging from 10.6 to 27.7 °c for more than 1100 days. the stable removal efficiencies for total codcr and ss ...

An up-flow anaerobic sludge blanket (UASB) reactor targeting sulfate reduction was operated under a constant TOC/S-SO42− ratio of 1.5 ± 0.3 g C/g S for 639 days using crude glycerol as carbon source. A filamentous and fluffy flocculant material, namely slime-like substances (SLS), gradually accumulated in the bioreactor after cease methanogenic activity. The accumulation SLS followed by decreas...

O trabalho teve como objetivo remover matéria orgânica e nutrientes de efluentes advindos uma indústria processamento pescado. foi realizado no laboratório saneamento da UFMG. sistema tratamento em dois estágios feito escala bancada sendo constituído por um reator anaeróbio com manta lodo forma Y (UASB ) acoplado a ele filtro percolador (FA) tendo material preenchimento conchas ostras. Os valor...

Source separated toilet water (black water; BW) is an important alternative nutrient source for agriculture. However, reuse and recovery of nutrients from BW limited by the presence pollutants, such as pathogens micropollutants. In this study, fate micropollutants during thermophilic hyper-thermophilic anaerobic digestion (AD) concentrated vacuum collected assessed. A total eight pharmaceutical...

Abstract The research and application of leachate in the treatment UASB reactors are increasing, but also has problems such as poor resistance to organic load impact unstable operation. In order improve anaerobic performance stability an up-flow sludge bed reactor (UASB) subjected high loading shock, pumice was added from incineration. reinforcement effect on efficiency studied by increasing in...

O despejo de efluentes parcialmente tratados com presença nutrientes pode causar eutrofização nos corpos hídricos. Para evitar este processo, é necessário o devido tratamento que visa a melhoria na qualidade final do efluente ser lançado. Este trabalho apresenta esgoto doméstico partir reator anaeróbio manto lodo (UASB) seguido lagoa alta taxa algas (LAT) posterior separação da biomassa algal a...

Tetracycline antibiotic wastewater with high chemical oxygen demand (COD) concentration and containing bio-refractory compounds was investigated in a lab-scale up-flow anaerobic sludge blanket (UASB) anoxic-oxic (A/O) reactor. Specific methanogenic activity (SMA) determined to reveal the inhibition levels of methane production volatile fatty acid (VFA) accumulation. The results showed that micr...
