چکیده

In this work, the efficiency and the technical feasibility of the anaerobic digestion of vegetable tannery industry primary sludge (VTPS) was investigated. Tests were conducted under mesophilic conditions in three laboratory scale (150 L) reactors. The investigation included two different solids retention time (15 and 25 d) and the codigestion of VTPS plus fleshing. Results showed that an increase of SRT, from 15 to 25 days, not many increases the specific biogas production of 0.06 NL biogas g VSS removed, but the addition of 1:4 (in mass) of fleshing in the feeding increases the VSS reduction of 10% at the end of the period.

Modeling the Disintegration Process in Anaerobic Digestion of Tannery Sludge and Fleshing

Mathematical modeling of anaerobic digestion (AD) is widely acknowledged as a powerful tool to v of the process and to support full-scale plant design, operation and optimization. In this work, a modified version of the IWA-ADM1 model is proposed to simulate the AD of tannery primary sludge (TPS) and fleshing, with special emphasis on the disintegration formulation. Multiple batch tests were pe...

A new kinetic model for biogas production from co-digestion by batch mode

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 co-digestion of cork based oil sorbent and cow manure or sludge

Cork, a material with great economic, social and environmental importance in Portugal, is also a good oil sorbent that can be used in the remediation of oil spills. The oil-impregnated cork can be easily removed, but requires further treatment. In the case of vegetable oil spills, anaerobic digestion may be a potential solution. This study aims to evaluate the effect of adding cork contaminated...

Anaerobic Treatment of Sewage Sludge and Grease Trap Sludge in Continuous Co-digestion

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...
