Struvite Precipitation as a Means of Recovering Nutrients and Mitigating Ammonia Toxicity in a Two-Stage Anaerobic Digester Treating Protein-Rich Feedstocks
Accumulation of ammonia, measured as total ammonia nitrogen (TAN), a product of protein u motion bowling ball decomposition in slaughterhouse wastes, inhibits the anaerobic digestion process, reducing digester productivity and leading to failure.Struvite precipitation (SP) is an effective means to remove TAN and enhance the buffering of substrates.
