Biogas Production from Fish Wastes in Co-digestion with Sewage Sludge
نویسندگان
چکیده
Fish wastes have great potential as a source of high valued organic carbon for methane production but also have limitation (high content of ammonia nitrogen). Anaerobic treatment of fish wastes is possible with co-digestion. The main issue for co-digestion process lies in balancing several parameters in the co-substrate mixture: macroand micronutrients, C:N ratio, pH, toxic compounds, biodegradable organic matter and dry matter. The aim of this work is to find optimal co-digestion substrates to enhance biogas production from fish wastes. The investigation give the answer about useful for determining the most proper ratios of different co-substrates that provide an optimized biodegradation potential or enhance methane potential. This work examines the potential for methane production from anaerobic co-digestion fish wastes, grass and sewage sludge (primary and secondary). Different type of inoculum were used (different SRT). The experiments were carried out in mesophilic temperature with using Automatic Methane Potential Test System (AMTPS II).

Anaerobic digestion (AD) has long been used to treat different types of organic wastes especially in the developed world. However, organic wastes are still more often considered as a waste instead of a resource in the developing world, which contributes to environmental pollution arising from their disposal. This study has been conducted at Bugolobi Sewage Treatment Plant (BSTP), where two orga...

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency, increased biodegradation of the treated materials, as well as increased biogas production. Most...

Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. Thus, the goal of this study is to develop a new kinetic model of biogas production with meani...

Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas, which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous...
