Biomethane production from vinasse in upflow anaerobic sludge blanket reactors inoculated with granular sludge
The main objective of this study was to evaluate the anaerobic conversion of vinasse into biomethane with gradual increase in organic loading rate (OLR) in two upflow anaerobic sludge blanket (UASB) reactors, R1 and R2, with volumes of 40.5 and 21.5L in the mesophilic temperature range. The UASB reactors were operated for 230 days with a hydraulic detection time (HDT) of 2.8d (R1) and 2.8-1.8d ...
متن کاملStart-Up Of An Upflow Anaerobic Sludge Blanket Reactor Treating Low-Strength Wastewater Inoculated With Non-Granular Sludge
The upflow anaerobic sludge blanket (UASB) process is known to be energy conservative biotechnology. Its low cost and low skill requirement render it to be a viable technology for reducing organic pollution loads. However, this system is facing a challenge in the treatment of low-strength wastewater especially inoculated with non-granular sludge. This work was performed to emphasis an in-depth ...
متن کاملEffects of Fe2+ on sludge granulation in upflow anaerobic sludge blanket reactors
Experiments were performed in parallel using six identical UASB (upflow anaerobic sludge blanket) reactors to examine the effects of iron (Fe2+) on sludge granulation during start-up. Introduction of Fe2+ at concentrations of 300 and 450 mg/L enhanced the granulation process in UASB reactors, while dosage of Fe2+ (150 mg/L) had little effect on the sludge granulation. The Fe2+concentration in g...
متن کاملUpflow Anaerobic Sludge Blanket Reactors for Treatment of Wastewater from the Brewery
Anaerobic digestion can be utilized to convert industrial wastewater into clean water and energy. The goal of this project was to set up lab-scale anaerobic digesters to collect data that will be used to develop and validate a predictive monitoring and controls solution to improve digester performance. The research project involved the design, construction, and instrumentation of lab-scale anae...
متن کاملUpflow 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...
