Modelling 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 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 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 کاملEnhanced lipid degradation in an upflow anaerobic sludge blanket reactor by integration with an acidogenic reactor.
Lipids inhibition and their degradation in dairy wastewater treatment were investigated in this study. A two-phase system, composed of an acidogenic continuously stirred tank reactor (CSTR) and a methanogenic upflow anaerobic sludge blanket (UASB) reactor, was compared with the single-phase system of a conventional UASB reactor. The systems were operated up to an organic loading rate of 8.09 g ...
متن کاملPerformance Evaluation of Hybrid Upflow Anaerobic Sludge Blanket Reactor in the Treatment of Dairy Waste Water
Dairy industries have shown tremendous growth in size and number in most countries of the world. These industries discharge wastewater which is characterized by high chemical oxygen demand, biological oxygen demand, nutrients, and organic and inorganic contents. Such wastewaters, if discharged without proper treatment, severely pollute receiving water bodies. For treatment of dairy waste water,...
