Degradation of methanethiol by methylotrophic methanogenic archaea in a lab-scale upflow anaerobic sludge blanket reactor.
In a lab-scale upflow anaerobic sludge blanket reactor inoculated with granular sludge from a full-scale wastewater treatment plant treating paper mill wastewater, methanethiol (MT) was degraded at 30 degrees C to H2S, CO2, and CH4. At a hydraulic retention time of 9 h, a maximum influent concentration of 6 mM MT was applied, corresponding to a volumetric loading rate of 16.5 mmol liter-1 day-1...
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...
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 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...
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 ...
