Production Of Hydrogen

Based on the description of the geological structure and hydrogeological conditions of the area in question, there is an opinion about the formation of hydrogen sulfide in groundwater. However, this view differs from the classical theory of sulfate reduction. It is substantiated that the production of hydrogen sulfide in groundwater due to the action of sulfate bacteria takes place not only in the recovery environment, but also in the oxidation zone. The validity of this view is confirmed by the analysis of deep hydrogeological wells and field survey data. Existence of hydrogen sulfide mineral springs within Kakheti is related to carbonate flysch. Their formation, circulation, including natural solutions is entirely in the form of carbonate flysch and is probably the origin of the formation of hydrogen sulfide healing waters. In addition to the mineral springs of Kakheti, the wide prospects of practical use of these waters are discussed, which is related to the picturesque nature and excellent climatic conditions of the area, which provides a great opportunity for resort-medical construction in the Kakheti region.

The Village

The study object is located in the main hydrographic unit of Shida Kakheti - on the left bank of Alazani river, along the southern slope of the Greater Caucasus and includes a strip starting from the village of Shakriani (Telavi district), ending with the regional center Lagodekhi (Lagodekhi gorge, left tributary of the Alazani river). Within this zone, hydrogen sulfide (H2S) mineral springs are prevalent. Besides, these waters are opened by exploratory - hydrogeological wells. Among these springs, "Torghva Bath" and "Lagodekhi Bath" are especially popular among the local population. The first of these is located in the upper reaches of the Story Valley, and the second - in Lagodekhi gorge, 7 km away from the settlement. The mineral springs "Muni Tsakaro" and "Mkrali Waters" are also important for their healing properties. Based on the analysis of theoretical and field materials, Kakheti hydrogen sulfide waters are characterized in detail and possibly their use for resort purposes.

Fox River

A pilot study was performed at the Fox River Fiber recovered paper processing company in DePere, Wisconsin, to determine the extent to which injection of oxygen and ozone could reduce the high chemical oxygen demand, COD, in the effluent and the effectiveness of the ozone/oxygen stream in suppressing production of hydrogen sulfide gas in downstream sewage lines. Adaptive Ozone Solutions, LLC, supplied the oxygen/ozone generation and injection system. Samples were analyzed both before and after oxygen/ozone injection. Hydrogen sulfide gas was continuously monitored at sewer stations downstream of Fox River Fiber. Results showed that with a very short contact time, effluent COD was reduced by over 15%. A simple kinetic model predicts that a contact time of fewer than 30 minutes could reduce COD by as much as 60%. In addition, downstream hydrogen sulfide gas production in the sewage mains was also better controlled, such that costly Bioxide applications could be reduced.

The paper presents the results of evaluating the efficiency of feed rations offered to broilers of the Arbor Acres cross, formed taking into account the climatic, geochemical conditions of Central Africa and its native food flora. The study was conducted on the basis of an experimental farm at the University of N’Djamena, the Republic of Chad. In the experiment, the authors used five formulas of feed rations, which are currently used by farms in the Republic of Chad for growing broiler chickens. They mainly contain locally availble ingredients. To increase the resistance of the poultry organism to unfavorable environmental factors, the chickens of the control and experimental groups were given “TETRACOLIVIT” and “AMIN’TOTAL” vitamins. The efficiency of feed rations was evaluated by determining the age dynamics of live weight, average weekly gains in live weight and blood biochemical parameters of broiler chickens of the Arbor Acres cross from 1 to 42 days of life. The formula of feed ration No. 1 proved to be the most effective in terms of the cross productivity.

Production Of Hydrogen

Both governmental and international programs support the promotion of biofuels and aim to increase the limit of renewable energy used in the fuel energy balance. Biogas is produced during the anaerobic methane fermentationprocess and it is known as a significant source of renewable energy, contributing to agriculture and environmental protection. Three types of biogas can be distinguished: biogas from sewage sludge, biogas collected from land`fils, andagricultural biogas. There are several possibilities of using upgraded biogas. Biogas can be used in cogeneration systems to provide heat and electricity, in transportation as a motor fuel and in the production of biohydrogen. Biogas upgrading process leads to a product which is characterized by the same parameters as compressed natural gas. Direct biogas use in the production of hydrogen is possible because of prior purification from traces like hydrogen sulfide, except carbon dioxide, by which the reaction can proceed in the desired manner.
