Electric pulse treatment of organic waste before anaerobic fermentation

One of the promising areas of processing organic waste from agriculture is through methane fermentation in biogas plants. They have important advantages over other methods of processing organic waste. Based on these problems, the article describes a method of processing organic waste under anaerobic conditions using electric pulse treatment of organic waste before loading into a biogas plant. The parameters of the production process of the bioenergy plant had the following values: humidity of organic waste 88-94%; the pressure of the gas phase in the bioreactor -2-3 kPa; the dose of daily updating of the mass volume in the bioreactor is 10% / day; the duration of one cycle of mixing 10 min; the frequency of daily mixing 17 days⁻1. Based on the equation, taking into account the listed optimal values of the factors, the biogas yield per 1 kg of OM was calculated and 0.146 m³ of BG/kg of OM was obtained. Laboratory and production results are given, as well as a comparison of the data obtained.
