The objective of the study was to examine the application of the Anaerobic Digestion Model No. 1 (ADM1) developed by the IWA task group for mathematical modelling of anaerobic process. Lab-scale temperature-phased anaerobic digestion (TPAD) process were operated continuously, and were fed with co-substrate composed of dog food and flour. The model platform implemented in the simulation was a de...

Co-digestion of sludge with external substrates at wastewater treatment plants is a common means to use residual wastes, utilise available capacity in the digester and boost biogas production. The Benchmark Simulation Model No. 2 (BSM2) is a platform for comparing plant-wide control strategies and includes among other things a model of the activated sludge process and the digester at a treatmen...

Particle size may significantly affect the speed and stability of anaerobic digestion, and matching the choice of particle size reduction equipment to digester type can thus determine the success or failure of the process. In the current research the organic fraction of municipal solid waste was processed using a combination of a shear shredder, rotary cutter and wet macerator to produce stream...

• The role of biogas bubbles in mixing is significant lower mixer rotation speeds. Considering bubble creation does not change the velocity gradient. 1-cm/s threshold for dead volume can show generation effect. A strategy capable handling a suitable agitation within digester tanks necessity order to assure continuous contact substrates and degraders inside bioreactors. As an energy demanding pr...

plug-flow digesters with periodic loading mechanism are more enthusiastic than fully mechanized digestion plants for the majority of small or medium scale farms according to the costs and operational complexities. a dual-compartment plug-flow reactor equipped with a passive heating system was designed and experimentally operated by purpose of demonstrating a simple and low cost technology for h...

Bioelectrochemical systems (BESs) can be integrated in situ into anaerobic digesters for increasing methane (CH 4 ) content of biogas. Using BES ex improving biogas quality has recently been gaining attention. However, information on the process under thermophilic conditions is very limited. In this study, we placed a cathode in-line at exit gas from digester to convert carbon dioxide (CO 2 CH ...

Numerous initiatives have been undertaken to circumvent the problem of antibiotic resistance, including the development of new antibiotics, the use of narrow spectrum antibiotics, and the reduction of inappropriate antibiotic use. We propose an alternative but complimentary approach to reduce antibiotic resistant bacteria (ARB) by implementing more stringent technologies for treating municipal ...
