The study explores the influence of physicochemical pretreatment on the performance of upflow anaerobic sludge blanket (UASB) reactors treating synthetic textile wastewater. Physicochemical pretreatment in this study utilized a new composite coagulant magnesium chloride added with aluminum chlorohydrate which produced nearly complete color removal and a partial chemical oxygen demand (COD) remo...

The anaerobic treatment of low strength domestic sewage at low temperature is an attractive and important topic at present. The upflow anaerobic sludge bed (UASB)-digester system is one of the anaerobic systems to challenge low temperature and concentrations. The effect of sludge recirculation rate on a UASB-digester system treating domestic sewage at 15 °C was studied in this research. A sludg...

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...

Wastewater management remains a major challenge in developing countries due to the lack of adequate infrastructure, making need for economically viable and efficient technologies that can be sustained by emerging economies imperative. The upflow anaerobic sludge blanket (UASB) reactor represents an low-cost technology produces by-products from which valuable resources recovered. This study asse...

The objective of this study was to determine the density anaerobic granules on different heights a full-scale Upflow Anaerobic Sludge Bed reactor. defined through settling velocities granules, measured in In study, granular calculated with and developed mathematical model. model is based Stokes experiment, were taken from an reactor, 0.6 7.6 m. granules’ diameters varied between 1 5 mm. six vel...

The low-pressure reverse osmosis (LPRO) process is a recent development of (RO) technology for the reduction in RO energy consumption and operation cost. goal this study was to investigate performance LPRO processes treatment reuse effluent discharged from brewery upflow anaerobic sludge blanket bioreactors (UASB). In study, three different commercially available membranes were tested evaluate ...

The present work aimed to investigate the microbial dynamics during the anaerobic treatment of the azo dye blue HRFL in bench scale upflow anaerobic sludge bed (UASB) reactor operated at ambient temperature. Sludge samples were collected under distinct operational phases, when the reactor were stable (low variation of color removal), to assess the effect of glucose and yeast extract as source o...
