Basics of Anaerobic Digestion
39,90 € *
ggf. zzgl. Versand

Anaerobic Digestion is a series of chemical reactions during which organic material is decomposed through the metabolic pathways of naturally occurring microorganisms in an oxygen-depleted environment.In nature this type of breakdown typically occurs in warm wet and dark environments, such as in the digestive tracts. The microorganisms are exploited in the biotechnological process of anaerobic digestion both to reduce the pollution caused by organic wastes and to produce methane, which can be used as a fuel. The number and types of microorganisms present in digesters are likely to depend upon the type of digester, its operating conditions and the waste composition. Anaerobic Digesters can be used on any carbon containing industrial wastewater i.e. food processing, pulp and paper, sugar and distillery, slaughterhouse, cheese whey and diary units, brewing industry and municipal sludge. Also, they provide an effective method for turning residues from different wastes, biogas (rich in methane which can be used to generate heat and/or electricity), fiber (this can be used as a nutrient-rich soil conditioner) and liquor (this can be used as liquid fertilize).

Biodiesel is receiving increased attention as an alternative, non-toxic, biodegradable and renewable diesel fuel. Biodiesel comes in use due to depletion of petroleum fuels and the environment benefits. Biogas can also be used with the biodiesel in I.C engine because of its better mixing ability and clean burning nature with very minor modifications in the engine. The usage of oxygenated fuels can reduce the particulate matter (PM) emissions from the engine without large modification of the engine. The present study has conducted to evaluate the properties of rice bran biodiesel and effect on the performance and emissions characteristics of C.I. engine using rice bran oil methyl ester with oxygenated fuel of Diethyl Ether blended with diesel as a pilot fuel and biogas as a gaseous fuel under dual fuel mode. This study is conducted in two phases. In the first phase, the blends of D80-B10-DEE10 and D60-B20-DEE20 with the use of biogas at a fixed flow rate of 0.9 kg/hr are performed at different load conditions and compared with diesel. In the second phase, the blends of D80-B10-DEE10 and D60-B20-DEE20 are performed at different load conditions.

The first experiment was carried out to investigate the effect of inoculating sweet pepper seeds and transplant roots with Nitrobin (contains N-free living bacteria, Azotobacter and Azospirillium) and Phosphorin (contains a PDB such Bacillus) in order to decreased the needed N and P fertilizers required for growing and producing sweet peppers under clay loam soil conditions. The second experiment aimed to study the effect of different organic fertilizer sources (FYM, Chichen manure, Biogas manure and Agrolig) in order to determine the optimum organic level and source required for clean sweet pepper production .i.e the highest fruit yield with least contamination.

Anaerobic Digestion of Swine Manure with Switch...
54,90 € *
ggf. zzgl. Versand

Anaerobic digestion of biomass for biogas production has been developed for a long period of time. In recent years, anaerobic co-digestion in which two or more substrates are treated together has been applied worldwide since the biogas production is improved through this combined process. The book is divided into two parts. Chapter one introduces the biochemical process of anaerobic digestion, anaerobic digesters, feedstocks and recent studies in anaerobic co-digestion. Chapter two illustrates a batch study of anaerobic co-digestion of swine wastewater with switchgrass and wheat straw under mesophilic conditions and studies the effect of total solids concentration on methane production. The book will be a good reference for researchers in related areas.

Biogas Production in Africa: Benefit Potentials...

Bioenergy production from agricultural crop biomass or residues has gained interest recently due to the escalating cost of fossil fuels and the need to mitigate global warming caused by increasing GHG emissions. Of all the different feed stocks used for bioenergy production in Africa, cassava biomass potentially offers multiple benefits for producing biofuels such as biogas. This book, therefore, highlights the bioenergy (biogas) potential of the crop in Africa. The basic agricultural properties of cassava were discussed including its high carbohydrate content and total dry matter. Its ability to thrive in all ecological zones with one of the best blue water-footprints especially in drought conditions and relatively low fertility soils. The crop therefore requires low agricultural input. The various pre-treatment techniques as well as the advantages and disadvantages of each technology for cassava biogas production were analysed. A holistic view on the highly publicised food vs. energy debate were provided. The book recommends cassava and its biomass as the next energy crop for bioenergy production and should be useful to future researchers and government policymakers in Africa.

Calotropis a laticiferous xerophyte, is a potential source of biogas with the following features: a perennial shrub, distributed in the tropical and subtropical areas in all types of soils and environmental conditions, requiring no cultivation practices and not grazed by animals. Inspite of all these advantages, the toxic secondary metabolites were feared to be the hindrance for utilizing the biogas residue as manure. Hence, the reduction of toxicity during biomethanation was assessed in this study. For the assessment, the qty of biogas generated, phytochemical changes and macronutrients during biomethanation, natural bacterial population in the rhizoplane and rhizosphere, antagonistic activity of Calotropis on the rhizosphere bacteria and the reduction of some toxic secondary metabolites were analyzed. When Calotropis biomass was used as a substrate for biomethanation, quick initiation, prolonged generation and higher production of biogas occurred. Hence, Calotropis biomass can be used as a source of biogas to solve the energy crisis. To manage the fertilizer demand, the fermented residue with rich plant macronutrients and reduced toxins can be safely used as manure.

The main objective of this work is to study the possibility of using dairy manure in Biofert production to eliminate the pollution effect and contribute in solving bio fertilizer sacristy problem. This study was carried out to investigate the most important factors affecting the Biofert production such as temperature, agitation speed and aeration rate to obtain the proper factors for optimum production of the nutrient solution (Bio-fertilizer). Two different systems of aeration were studied. After obtaining the proper nutrient solution for production, field experiment was conducted to study the effect of the properties of different of nutrients solution on the yield and yield parameters of tomato plants. Biogas production under different conditions was also determined.
