    The liquid phase recirculation under methanogenic fermentation of chicken manure
    (Lviv Politechnic Publishing House, 2018-10-26) Yevheniy, Shapovalov; Anatoliy, Salyuk; National Center "Junior Academy of Sciences of Ukraine"; National University of Food Technologies
    The article is devoted to the analysis of the methanogenesis of chicken manure with effluent’s liquid phase recycling with and without nitrogen stripping. It was determined that methanogenesis with full recirculation of the liquid phase is possible both with the sorption of ammonia nitrogen and without it. However, it was characterized by an inhibited state. Methane production was 0.51 l/l in a reactor with ammonia stripping and 0.23 l/l in a reactor without ammonia stripping. The ammonia removal efficiency was 12.5 % ammonia nitrogen. Proposed technology stripping of ammonia is characterized by a positive economic effect.
