The exploitation of whole biogas energy is locally limited and utilization of natural gas transport system requires CO removal or B 2 conversion to methane. Chemical methods of upgrading biogas to bio-methane have disadvantage in demand of high pressure and temperature. Biological conversion of CO2 and hydrogen to methane is well known reaction and is carried out by hydrogenotrophic methanogenic bacteria. Reducing equivalents to biotransformation of carbon dioxide from biogas or other resources to bio-methane can be supplied by external hydrogen. The rapidly developing renewable energy carriers include electricity from wind and solar energy. Discontinuous electricity production combined with fluctuating utilization cause serious storage problems that can be solved by power-to-gas strategy representing production of storable hydrogen via electrolysis of water. Possibility of subsequent repowering of energy of hydrogen to the easily utilizable and transportable form is biological conversion with CO2 to bio-methane. The aim of our project is to find the optimal conditions of the technology of biological reduction of CO2 with H2 in terms of process parameters and device type. Biomethanization of CO2 can be applied directly to anaerobic digesters being fed with organic substrates, or in external bioreactors. Experiments started with hybrid anaerobic reactors (up-flow sludge bed reactor with packed bed in the upper part) fed with distillery slops as organic substrate and gaseous hydrogen was introduced to the bottom of reactor. The major bottleneck in the process is gas-liquid mass transfer of H2 and the method of effective input of hydrogen into the system has to be optimized. The possibilities of an implementation of the technology to biogas plants will be suggested based on results of the project.

This study explored the feasibility of using biogas to fuel buses in the city of Johannesburg, South Africa. Biogas is a renewable fuel that can be used for electrical power, heating/cooling, and as a transport fuel. However, the use of biogas for transportation delivers more financial value-adding compared to using biogas for electricity- US$18/GJ for transport fuel and US$9/GJ for electricity. In addition, the use of biogas to fuel city buses has additional local benefits; such as reducing air pollution from vehicle tail-pipe emissions, reducing traffic congestion, and enhancing the social inclusivity of transportation. The cultivation of land and use of energy crops as feedstock for biogas production will require at least seven hectares per bus; which will place additional demands on the city’s scarce land resources and create potential conflicts with food production. Biodegradable wastes are alternative feedstock for biogas production that avoids these impacts and can be supplied at a cost that is currently competitive with the price of other transport fuels, such as diesel and petrol. However, the feasibility depends on the combined economies of scale for biogas production, upgrading and distribution; such that large-scale biogas production (>2000 Nm3/h) is required to compete with petrol and diesel market prices. Using size-location modelling, we identified the optimal locations for two large biogas facilities that use the organic fraction of municipal solid waste as feedstock to produce upgraded biogas that can fuel up to six-hundred city buses. The benefits of this project include diverting organic waste from landfill, reducing carbon emissions, improving local air quality, increasing transportation efficiency, delivering new opportunities for transit orientated development and facilitating the transition to a Green economy.

    Re-examining the Role of Nuclear Fusion in a Renewables-Based Energy Mix T. E. G. Nicholasa,∗, T. P. Davisb, F. Federicia, J. E. Lelandc, B. S. Patela, C. Vincentd, S. H. Warda a York Plasma Institute, Department of Physics, University of York, Heslington, York YO10 5DD, UK b Department of Materials, University of Oxford, Parks Road, Oxford, OX1 3PH c Department of Electrical Engineering and Electronics, University of Liverpool, Liverpool, L69 3GJ, UK d Centre for Advanced Instrumentation, Department of Physics, Durham University, Durham DH1 3LS, UK Abstract Fusion energy is often regarded as a long-term solution to the world's energy needs. However, even after solving the critical research challenges, engineer- ing and materials science will still impose significant constraints on the char- acteristics of a fusion power plant. Meanwhile, the global energy grid must transition to low-carbon sources by 2050 to prevent the worst effects of climate change. We review three factors affecting fusion's future trajectory: (1) the sig- nificant drop in the price of renewable energy, (2) the intermittency of renewable sources and implications for future energy grids, and (3) the recent proposition of intermediate-level nuclear waste as a product of fusion. Within the scenario assumed by our premises, we find that while there remains a clear motivation to develop fusion power plants, this motivation is likely weakened by the time they become available. We also conclude that most current fusion reactor designs do not take these factors into account and, to increase market penetration, fu- sion research should consider relaxed nuclear waste design criteria, raw material availability constraints and load-following designs with pulsed operation.

Received 31 December 2012; accepted 16 June 2013 Abstract: Anaerobic wastewater treatment is receiving renewed interest because it offers a means to treat wastewater with lower energy investment. Because the microorganisms involved grow more slowly, such systems require clever design so that the microbes have sufficient time with the substrate to complete treatment without requiring enormous reactor volumes. The anaerobic baffled reactor has inherent advantages over single compartment reactors due to its circulation pattern that approaches a plug flow reactor. The physical configuration of the anaerobic baffled reactor enables significant modifications to be made; resulting in a reactor which is proficient of treating complex wastewaters which presently require only one unit, ultimately significant reducing capital costs. This paper also concerns about mechanism, kinetic and hydrodynamic studies of anaerobic digestion for future application of the anaerobic baffled reactor for wastewater treatment.

The experiment was carried out in two exploitation variants that were both conducted in a laboratory model of the hybrid bioreactor: (I) cycles of 120 min of aeration and 60 min of no aeration with a constant sewage dosage, and (II) cycles 60 min of aeration and 60 min of no aeration, with a periodic sewage dosage in the no-aeration phase. The experiment was carried out on real sewage primarily treated in a septic tank. The amount of pollution removal was calculated and compared with the mandatory standards according to Polish law. Moreover, the susceptibility of the sewage to the biological treatment, nitrification, and denitrification activity was determined. The research shows a higher effectiveness for the 60/60 model in comparison to the 120/60 model. High operation efficiency was observed regarding the removal of organic pollution and nitrate nitrogen. The tested structure showed very low nitrification activity combined with intense denitrification.

Rajesh Banu,1 Sudalyandi Kaliappan1* and Dieter Beck2 1Centre for Environmental Studies (CES), Anna University, Chennai – 600025, Tamilnadu State, India 2Indo-German Project, Centre for Environmental Studies, Freiheits Str. 195, 42853 Remscheid, Germany Sago, tapioca starch, is manufactured by over 800 small-scale units located in the Salem district of the State of Tamilnadu, South India. These units generate large quantities of high-strength wastewater requiring elaborate treatment prior to dis- posal. The present study is an attempt to treat the sago wastewater using a hybrid reactor, which combines the advantages of both fixed-film and up-flow anaerobic sludge blanket systems. A hybrid reactor with a volume of 5.9 L was operated at organic loading rates varying from 10.4 to 24.6 kg COD/m3d. After 120 d of start-up, an appreciable decrease in COD and efficient removal of solids were evident. The COD removal varied from 91 to 83%. While the removal of total solids was in the range of 56 to 63%, that of volatile solids varied from 67 to 72%. The methane production during the study period was in the range of 0.11 to 0.14 L CH4/g COD-d and the percentage was from 55 to 67%. The ideal organic loading rate (OLR) was determined on the basis of tolerance of the reactor towards higher organic loading rate and it was found to be 23.4 kg COD/m3d.

    ISSN XXXX XXXX © 2017 IJESC Research Article Volume 7 Issue No.8 Feasibility Study of Domestic Wastewater using Hybrid Process Prof. R. S. Adhau Assistant Professor Department of Civil Engineering Prof. Ram Meghe Institute of Technology &Research, Badnera, India Abstract: With the introduction of stringent effluent standards, it is the responsibility of wastewater treatment engineer to treat the wastewater to satisfy the requirement of receiving streams. The wastewater is conventionally treated either by Attached Growth System or by Suspended Growth System. Recently a new trend is developed to adopt the combination of Attached and Suspended Growth System of treatment. The combinations of treatment systems provide better results and as such the efforts will be made to study the efficiency of treatment. The combined activated & suspended growth system is advantageous for improvement of the efficiency. The present paper describes techniques for effective domestic waste management. Effort is made to treat the domestic waste by developing a technique such as Hybrid Process. Hybrid process is a technology which enhances the efficiency of domestic wastewater treatment. Hybrid process is a technique of using attached & suspended growth system by effectively using the advantages of both systems. The performance of various reactors best on attached & suspended growth system is discussed. Suitability of attached & suspended growth system is discussed thoroughly. The lab scale model is operated for different operating conditions at different detention time. To study the performance of the reactor a laboratory model is fabricated with steel having appropriate dimension. The model is provided with appropriate arrangements of inlet, outlet arrangements. Extensive study is carried to study the performance of reactor various parameter such as BOD, COD.
