Anaerobic co-digestion of a simulated organic fraction of municipal solid wastes and fats of animal and vegetable origin

چکیده
The potential of mesophilic anaerobic digestion for the treatment of fats of different origin through co-digestion with the organic fraction of municipal solid wastes (OFMSW) has been evaluated. Co-digestion process was conducted in a pilot plant working in semi-continuous regime in the mesophilic range (37 ◦C) and the hydraulic retention time (HRT) was 17 days. During the start-up period the digester was fed with increasing quantities of a simulated OFMSW (diluted dry pet food). When the designed organic loading was reached, co-digestion process was initiated. The fat used consisted of waste from the food industry (animal fat), its composition was very similar to that of the s a o r c s ©

Application of anaerobic digestion products of municipal solid food wastes in treating wastewaters
Anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.This technology is superior to the landfilling and also the aerobic composting. The aim of the present study was to examine whether the effluent Volatile Fatty Acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

As one of the most environmentally friendly and cost-effective method, anaerobic digestion (AD) has been widely studied and developed as a conventional technology to degrade biodegradable materials and produce biogas simultaneously. Various substrate sources are used in this process such as organic fraction of municipal solid waste (MSW), waste activated sludge (WAS), animal manures, agro-indus...
متن کاملSimulation of a Process Design Model for Anaerobic Digestion of Municipal Solid Wastes
Anaerobic Digestion has become a promising technology for biological transformation of organic fraction of the municipal solid wastes (MSW). In order to represent the kinetic behavior of such biological process and thereby to design a reactor system, development of a mathematical model is essential. Addressing this issue, a simplistic mathematical model has been developed for anaerobic digestio...

Introduction Until relatively recently, anaerobic digestion (AD) plants at farm or industry level treated the organic waste arisings from a single farm or from an individual industrial operation. The installation of centralised AD plants, treating animal manures and slurries from a large number of farms, and the increasing use of co-digestion of manures, food-processing wastes, sewage sludge an...
متن کاملAnaerobic digestion of municipal solid waste and agricultural waste and the effect of co-digestion with dairy cow manure.
Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...
