Exergy analysis of solar energy assisted biogas plants for Turkey
The energy quality of solar energy assisted biogas plants established in Izmir, Turkey was investigated in this study via exergy analysis. This study was assisted together with other energy and economy analysis of these plants. Firstly, the plant was operated at mesophilic temperature region and it was continuously fed with cattle manure. The biogas efficiency reached a value as high as 1.3 ...

The feasibility of trace element supplementation for stable operation of wheat stillage-fed biogas tank reactors
The aim of this study was to investigate the effect of trace element supplementation on operation of wheat stillage-fed biogas tank reactors. The stillage used was a residue from bio-ethanol production, containing high levels of sulfate. In biogas production, high sulfate content has been associated with poor process stability in terms of low methane production and accumulation of process ...

Anaerobic digestion of macroalgae: methane potentials, pre-treatment, inhibition and co-digestion
In the present study we tested four macroalgae species – harvested in Denmark – for their suitability of bioconversion to methane. In batch experiments (53 °C) methane yields varied from 132 ml g volatile solids−1 (VS) for Gracillaria vermiculophylla, 152 ml g VS−1 for Ulva lactuca, 166 ml g VS−1 for Chaetomorpha linum and 340 ml g VS−1 for Saccharina latissima following 34 days of incubation. ...

Biogas and Anaerobic Digestion in Relation to CH4 Methane Monitoring
The use of biogas as a renewable energy source currently accounts for 10 % of global primary energy consumption1 and is often heralded as the perfect example of the ‘circular economy’ – where waste products can be reused to generate energy for other processes in a self-perpetuating cycle.2Biogas consists of the mixture of gases produced by the breakdown of organic matter by bacteria under ...

GTI and the City of Tulare celebrate 25 years of converting waste to energy - case study
Energy conservation has always been extremely important to both the City of Tulare and the wastewater treatment facility. Since biogas can be used as fuel to generate electricity, the city wanted a means to reliably collect biogas from the BVF® reactor to recover the energy while also controlling odors and reducing greenhouse gas emissions. To address the City of Tulare’s needs, ...

Anaerobic treatment of crude glycerol from biodiesel production
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas ...

Treatment of corn ethanol distillery wastewater using two-stage anaerobic digestion
In this study the mesophilic two-stage anaerobic digestion (AD) of corn bioethanol distillery wastewater is investigated in laboratory-scale reactors. Two-stage AD technology separates the different sub-processes of the AD in two distinct reactors, enabling the use of optimal conditions for the different microbial consortia involved in the different process phases, and thus allowing for ...

Recovering biomethane and nutrients from anaerobic digestion of water hyacinth (Eichhornia crassipes) and its co-digestion with fruit and vegetable waste
The potential to recover bioenergy from anaerobic digestion of water hyacinth (WH) and from its co-digestion with fruit and vegetable waste (FVW) was investigated. Initially, biogas and methane production were studied using the biochemical methane potential (BMP) test at 2 g volatile solids (VS) L−1 of substrate concentration, both in the digestion of WH alone and in its co-digestion with FVW ...

Autogenerative high pressure digestion: anaerobic digestion and biogas upgrading in a single step reactor system
Conventional anaerobic digestion is a widely applied technology to produce biogas from organic wastes and residues. The biogas calorific value depends on the CH4 content which generally ranges between 55 and 65%. Biogas upgrading to so-called ‘green gas’, with natural gas quality, generally proceeds with add-on technologies, applicable only for biogas flows >100 m3/h. In the concept of ...

Turning waste into power
Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...

Biogas Cleaning
Removal of water vapor Origin In the biogas production process, water is an intrinsic part of both the material to be digested (biomass) and the process itself. Furthermore, water is the medium in which biogas production takes place, regardless of whether the digestion process is dry or wet, the biogas produced will contain water vapour. The amount of water vapour contained in the biogas ...
