Abstract

The purpose of this article is the observation of biogas production process, environment temperature and comparison of mixture rates of waste with water. Defined mixture reports are 1:1 and 1:2 (water-waste cattle). The average temperature set in experimental conditions is 24°C, ie within the limits mesophilic development process, ie between 20°C and 35°C. The experimental system of biogas production set up in the Didactic Experimental Economics, at the Agricultural University of Tirana. At the same time, unlike the conditions thermophilic requiring external power in the form of heat, to reach a temperature (55°C - 60°C), this experiment does not require 'extra cost' energy but could be created from an greenhouse (GH) environment type. Six (6) vessels used in the experiment are simple and modified with a plastic pipes communication system adapted to appeal to experiment. The average percentage of methane gas in the amount of biogas produced by the ratio 1:1 is 44.4% and the ratio of 1:2 is 37.5%. The impact of the mixture ratio and temperature constitute key factors associated with the process of fermentation and then the production of biogas. Comparing them will give us a clearer picture about the behavior of minidigesters reports under the influence of these conditions.
