The present study is an attempt to treat the coffee processing wastewater using upflow anaerobic hybrid reactor which offers the advantage of both suspended and attached growth anaerobic reactor systems. Upflow anaerobic hybrid reactor with a volume of 19.5 L was operated at 24 h hydraulic retention time. After the startup period, the reactor was evaluated by operating at different hydraulic re...
The performance of an upflow anaerobic sludge blanket (UASB) reactor and a hybrid UASB-filter reactor was investigated and compared for the treatment of domestic wastewater at different operational temperatures (28, 20, 14 and 10°C) and loading rates. For each temperature studied a constant CODt removal was observed as long as the upflow velocity was lower than 0.35 m/h. At these upflow velocit...
In this study, characterization and anaerobic treatability of leachate from Komurcuoda Sanitary Landfill located on the Asian part of Istanbul were investigated. Time based fluctuations in characteristics of leachate were monitored for an 8 month period. Samples were taken from a 200 m3 holding tank located at the lowest elevation of the landfill. COD concentrations have ranged between 18,800 a...
The wastewater discharged by poultry slaughterhouse industries are characterized mainly by high biochemical oxygen demand, high suspended solids and complex mixture of fats, proteins and fibers requiring systematic treatment prior to disposal. In this study, the performance of an upflow anaerobic filter reactor for treating Indian poultry slaughterhouse wastewater under low upflow velocity of 1...
A mathematical model for a hybrid anaerobic reactor (HAR), which uses self-immobilized anaerobic bacterial granules under completely fluidized condition, has been developed. Stoichiometry of glucose fermentation into methane has been considered in this model. The model includes: (1) a biofilm model which describes substrate conversion kinetics within a single granule; (2) a bed fluidization mod...
we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...
The selection of optimum high strength wastewater treatment process is complicated. Be familiar with wastewater treatment methods is not enough to design a plant. In this research, five alternative wastewater treatment methods (upflow anaerobic sludge blanket (UASB) + membrane bioreactor (MBR), UASB + Extended aeration (EA), Anaerobic baffled reactor (ABR), anaerobic lagoon (ANL) + aerated lago...
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...
