Packing can have varying material, surface area, flow area, and associated pressure drop. To avoid ammonium inhibition and thus to ensure a higher biogas yield, it is therefore appropriate to remove the ammonium prior to the digestion process. This reaction depends on the stoichiometry of the reaction and the concentration of the reactants. What is the pressure drop per tray? This stripping efficiency is quite similar to that obtained by Jiang et al. As the pH of the incubation mixtures (digestate+substrate) remained constant at about pH 7.8 during the entire digestion process, there was no effect on the equilibrium of NH4+ and NH3.

Water pressure before nozzles: 100 - 170 kN/m2. Since the digestate of an anaerobic digestion has both a high temperature and a high TAN content, it is very suitable for ammonia stripping [15]. This flask is placed in an incubator (Memmert, Germany) with an operating temperature of 323.15K or 50C (digestate was taken from a thermophilic digestion with the same operating temperature). This allows for the minimization of flow. Investigation of the inhibitory effect of ammonium. We, however, have to take into consideration that only a limited increase of temperature (323.15K or 50C) and pH (8.5) was applied, as we did not want to deactivate the micro-organisms that were present in the supernatant of the digestate. Lattice design work has been increasing of late that will further improve these characteristics.[2]. Water pressure before nozzles: 100 - 170 kN/m2. Assume a foaming factor of 0.90, trays that have an and a surface tension of 70 dyne/cm and ignore the contribution of the solute to the physical properties of the carrier streams.

The operation of removing the absorbed solute from the solvent is called stripping . (Related to effect of gas and liquid flows on the velocity of packed column). From a stripping prospective, it is designated to separate the raw digestate into a solid (thick) and a liquid (thin) fraction. After stripping the ammonium, the pH of the treated supernatant was lowered to the original pH of 7.8 by means of concentrated HCl and recombined with freshly obtained thick fraction (obtained after centrifugation of digestate). Among them are the entering conditions, the degree of recovery of the solute needed, the choice of the stripping agent and its flow, the operating conditions, the number of stages, the heat effects, and the type and size of the equipment.[2]. This experiment is referred to as the treated digestate. Its origin and characterization are explained in Sects. A changed pressure drop over a significant range of time can be an indication that the packing may need to be replaced or cleaned.
