3. 2. Stabilizing biogas processes at high ammonia : effects of acetate pulse-feeding on the microbial population

   University essay from SLU/Department of Molecular Sciences

   Author : Oscar Dolk; [2020]
   Keywords : biogas; anaerobic digestion; ammonia inhibition; acetate enrichment;

   Abstract : This study investigated the problem of ammonia inhibition in biogas reactors, commonly occurring when protein rich substrates are used in anaerobic digestion processes. Ammonia inhibition is one of the foremost causes of failure in anaerobic digestion, leading to process instability, with symptoms commonly expressed as; reduction in biogas produced, decreased methane content in the gas and accumulation of volatile fatty acids.
