It also allows for care of high traffic areas, eliminating all the mess, smell of the stripping chemical and down time that traditional stripping methods require. As mentioned, the raw digestate is separated into a thick fraction and a thin fraction (also called the supernatant) by means of a centrifuge. Absorption of the stripped NH4+ results in this case in NH4NO3, which has a higher intrinsic value as nitrogen fertilizer. 26, 6983 (2017), Schievano, A., Tenca, A., Lonati, S., Manzini, E., Adani, F.: Can two-stage instead of one-stage anaerobic digestin really increase energy recovery from biomass? 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. Stripping Tower - posted in Student: Dear friends,I'm familiar with Packed Tower designing more or less and before this I was sure that Acid stripping towers were another kind of packed towers.but when I used the same method which I use in design a common sulfuric acid packed towers, the results are so different with an example stripping tower which we have in our project. After addition of substrate, the mixture is subjected to an anaerobic digestion and the result is compared with that of an untreated digestate from which no TAN was removed. 2.
