NettetThe dynamic pressure method (DPM) is used for measurement of k L a in a 1‐m 3 pilot scale fermentor in coalescing (distilled water) and noncoalescing (0.3 M Na 2 SO 4 aqueous solution) batches. The method consists in recording oxygen concentration in a batch after a small pressure change (20 kPa) in the fermentor. Nettet1. mai 1993 · This technique is considered as a simplified form of the well-known dynamic pressure method (DPM) (Linek et al., 1989; Linek et al., 1993; Scargiali et al., 2014).
