However, the term sorption covers both absorption and adsorption processes, as well as the ion-exchange process. This experiment is referred to as the treated digestate. Required fields are marked *. Both experiments were performed at 323.15K (50C) in the configuration shown in Fig. border-radius: 5px; 3. www.ChemicalEngineeringGuy.com The function of a tray is to facilitate contact between the vapor phase and liquid phase so that mass transfer between the 2 phases can take place. Bioeng. line-height: 1.5; During the stripping, the ammonium present in the supernatant is volatilized into ammonia through a combination of temperature and pH increase. For an absorption column, is the bottom stage. This proves that (1) the centrifugation of the digestate into a thick fraction and a supernatant does not affect the biogas formation as a digestion experiment on the combined fractions resulted in the same biogas production as the untreated digestate and (2) the higher biogas yield using the treated digestate is therefore not due to the centrifugation step but due to the reduced TAN level. 101, 118125 (2010), Bonmat, A., Flotats, X.: Air stripping of ammonia from pig slurry: characterisation and feasibility as a pre- or post-treatment to mesophilic anaerobic digestion. margin-top: 30px; {-[VA_X&`%b Hz7'Txp4%T The first criterion is the percentage ammonium removal from the supernatant.
