A novel anaerobic treatment system, the anaerobic migrating blanket reactor (AMBR), was developed after completing a parallel study with upflow anaerobic sludge blanket (UASB) and anaerobic sequencing batch reactor (ASBR) processes. Using sucrose as the main component of a synthetic wastewater, the AMBR achieved a maximum chemical oxygen demand (COD) loading rate of 30 g.l .day 1 at a 12-h hydr...

feasibility of methanolic wastes treatment containing chlorophenol in experimental uasb reactors i.e. r-i and r-ii working side by side constantly for a couple of almost 32 weeks were studied. uasb reactor r-i was initiated by utilizing the digested sludge alone, whereas, the uasb reactor r-ii was startedup by adding an activated carbon of an effective size 1.5-2.5mm to the digested sludge with...

two uasb reactors r-i and r-ii, each of 10liters capacity, made up of acryl material wereoperated parallel and continuously for a period of 220 days, using actual effluent of the nssc pulp and papermill, at mesophilic temperature and neutral ph. the main objective was to investigate the treatabilityperformance of the reactors at varying olr and hrt in terms of toc and lignin removal. the reacto...

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...
