The aim of this paper is to synthesize and analyze information on how the process of granulation is affected by environmental and operational conditions in the reactor. Various factors affecting granulation process as gleaned from the literature are organic loading rate (OLR), upflow velocity (Vup), sludge volume index (SVI), specific methenogenic activity (SMA), VSS/SS ratio, liquid in flow ra...
Sulfate-reducing bioreactors for sulfide production are the initial stage of processes targeting elemental sulfur recovery from sulfate-rich effluents. In this work, principal reactions involved in glycerol fermentation and sulfate reduction using its products as electron donors were assessed together with their specific consumption/production rates. A battery batch activity tests without perfo...
the down-flow hanging sponge (dhs) reactor, which was developed for post-treatment of effluent from up-flow anaerobic sludge blanket (uasb) process treating sewage, uses polyurethane sponge as media to retain biomass. wastewater is trickled from the top of the reactor and purified by microorganisms retained both inside and outside of the sponge media as the wastewater flows vertically down thr...
nowadays, with the industry development, a lot of waste is produced damaging the environment. among wastewater treatment methods, anaerobic techniques have been highly regarded due to numerous advantages. in anaerobic systems, upflow anaerobic sludge blanket (uasb) reactor has many features. in this study using computational fluid dynamics techniques, three-phase reactor hydrodynamics in two an...
