Ammonia Inhibition in High-Solids Biogasification: An Overview and Practical Solutions

Kayhanian, M.·1999·Environmental Technology

Abstract

A comprehensive literature search was conducted to evaluate ammonia inhibition in biogasification. An overview of ammonia inhibition including the fundamentals of biochemical pathways of nitrogenous compounds, ammonia inhibition mechanisms and impact of free ammonia inhibition was conducted. Past studies and the experience gained with the pilot project at the University of California, Davis (UC Davis) were reviewed and discussed. Long-term experimental studies at the pilot scale revealed that ammonia inhibition in a high-solids thermophilic anaerobic digestion occurs at ammonia concentration of 1200 mg l−1. Two methods: (1) dilution of digester content with fresh water and (2) adjustment of feedstock C/N ratio were evaluated to mitigate ammonia inhibition. Both methods were found to be practical and effective.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
