Abstract Pseudomonas aeruginosa PAO1 wild type and a mucoid derivative (FRD1) which over produces alginate were used to foul reverse osmosis (RO) membranes. When operated at constant flux, biofilm formation on the RO membrane resulted in slow rise transmembrane pressure (TMP) of 22% for initial four days operation, followed by sharp increase 159% following two days. The TMP was probably due surface, then accelerated rate biofouling through effect concentration polarization. At later stages...
A fluid dynamic gauging (FDG) technique was used for on-line and in situ measurements of Pseudomonas aeruginosa PAO1 biofilm thickness strength on flat sheet polyethersulphone membranes. The are the first to be successfully conducted a membrane cross-flow filtration system under constant permeation. In addition, FDG demonstrate removal behaviour biofilms through local energy estimation, which other conventional such as flux TMP cannot provide. findings suggest that can provide valuable...
