Also in this case, 50mL of substrate was added to the untreated digestate, after which the digestion was started. text-decoration: none !important; In our experiment, simultaneously 80% of the stripped ammonia was absorbed in 1M H2SO4 in the scrubbing part. In the stripping part, the supernatant (thin fraction) of the digestate is continuously stirred using a magnetic stir bar and is continuously pumped over a Vigreux column at a flow rate of 7 Lh1 using a peristaltic pump (WatsonMarlow 520S, Belgium). Two additional combinations were tested: (1) a Dufton column in the stripping part and a Vigreux column in the scrubbing part and (2) vice versa. However, this is the most unfavourable column combination because the other two criteria were far from optimal, namely a low ammonium removal percentage (67%) in combination with the largest time interval (28h). } In industrial applications the liquid and vapor streams can have co-current or countercurrent flows.
