Upflow Anaerobic Sludge Blanket (uasb) Reactor in Wastewater Treatment
Under anaerobic conditions, organic pollutants in wastewater are degraded by microbes producing methane and carbon dioxide. The degradation process is effective compared to the more conventional aerobic processes and produces only 5-10% of sludge. This saves considerably on cost associated with the sludge disposal. Among anaerobic technologies, the most popular ones is the upflow anaerobic slud...
متن کاملModelling of an Upflow Anaerobic Sludge Blanket reactor
A model describing both physical and biological processes in Upflow Anaerobic Sludge Blanket (UASB) reactors was developed. The main objective of the modelling was to take into account the transient growth of the microorganisms from the start-up of the reactor until a steady state is reached. In addition, the model considers the degradation of the substrate and its reaction with the biomass, wh...

متن کاملInfluence of polymer addition on granulation in upflow anaerobic sludge blanket reactor: A review
The upflow anaerobic sludge blanket (UASB) reactor has been used successfully treat a variety of wastewaters. The aim of this review is to synthesize and analyze information on how the process of granulation is affected by environmental and operational conditions in the reactor. The factors reviewed are strength of substrate, nutrients, multivalent cations and heavy metals, exocellular polymer,...
متن کاملMicrobial and physicochemical characteristics of compact anaerobic ammonium-oxidizing granules in an upflow anaerobic sludge blanket reactor.
Anaerobic ammonium oxidation (anammox) is a promising new process to treat high-strength nitrogenous wastewater. Due to the low growth rate of anaerobic ammonium-oxidizing bacteria, efficient biomass retention is essential for reactor operation. Therefore, we studied the settling ability and community composition of the anaerobic ammonium-oxidizing granules, which were cultivated in an upflow a...
