Recovery of ammonia and sulfate from waste streams and bioenergy production via bipolar bioelectrodialysis.
Ammonia and sulfate, which are prevalent pollutants in agricultural and industrial wastewaters, can cause serious inhibition in several biological treatment processes, such as anaerobic digestion. In this study, a novel bioelectrochemical approach termed bipolar bioelectrodialysis was developed to recover ammonia and sulfate from waste streams and thereby counteracting their toxicity during ana...
متن کاملStruvite Precipitation as a Means of Recovering Nutrients and Mitigating Ammonia Toxicity in a Two-Stage Anaerobic Digester Treating Protein-Rich Feedstocks.
Accumulation of ammonia, measured as total ammonia nitrogen (TAN), a product of protein decomposition in slaughterhouse wastes, inhibits the anaerobic digestion process, reducing digester productivity and leading to failure. Struvite precipitation (SP) is an effective means to remove TAN and enhance the buffering of substrates. Different Mg and P sources were evaluated as reactants in SP in aci...
متن کاملDevelopment of Methane Fermentor for Restraining Ammonia Inhibition
Anaerobic digestion of swine wastes is an attractive practice in which both pollution control and energy recovery can be achieved. Nowadays, anaerobic digestion becomes a promising process due to its beneficial output including renewable energy production and mitigation of pollutant emissions. However, the high concentration of ammonium in manure and the produced ammonia as a common metabolic e...
متن کاملAmmonium recovery from reject water combined with hydrogen production in a bioelectrochemical reactor.
In this study, a bioelectrochemical reactor was investigated for simultaneous hydrogen production and ammonium recovery from reject water, which is an ammonium-rich side-stream produced from sludge treatment processes at wastewater treatment plants. In the anode chamber of the reactor, microorganisms converted organic material into electrical current. The electrical current was used to generate...
متن کاملAssessment and parameter identification of simplified models to describe the kinetics of semi-continuous biomethane production from anaerobic digestion of green and food waste
Biochemical reactions occurring during anaerobic digestion have been modelled using reaction kinetic equations such as first-order, Contois and Monod which are then combined to form mechanistic models. This work considers models which include between one and three biochemical reactions to investigate if the choice of the reaction rate equation, complexity of the model structure as well as the i...
