It was reported in previous works that the performance of ultrafiltration in tubular membranes could be improved by concentrically inserting a steel rod, and further improved by wrapping a wired spiral of uniform angles on the entire rod, to increase fluid velocity and thus, to decrease the concentr

Predicting equations for the permeate flux of membrane ultrafiltration in a tubular module were derived from momentum balance with the considerations of declining flow rate and transmembrane pressure along the membrane tube. Correlation predictions are confirmed with the experimental results. The ef
Protease N (IUB 3.4.24.28, Bacillus subtilis) enzyme was used to continuously hydrolyse an initial 5% (w/v) whey protein isolate (86.98%, Kjeldahl nitrogen Γ 6.38) for 5 h at pH 7.0 and 55 β’ C in a 10 kDa tangential flow filter (TFF) enzymatic membrane reactor (EMR). The retentate temperature (A: 25
