Web1 day ago · These changes in backwash behavior indicate the relative magnitude of particle-membrane interaction forces of different origins. A deeper understanding of the interactions between particulate foulants and membranes during membrane filtration and backwash will allow a more targeted membrane design for various membrane filtration processes. Web13 Apr 2024 · The results indicated that Milli-Q water backwash was superior to UF permeate backwash in cleaning HA-fouled membranes, and the backwash water containing Na+ or HA outperformed Milli-Q water in ...

Web1 Feb 2024 · The influence of the interaction between aquatic humic substances and the algal organic matter (AOM) derived from Microcystis aeruginosa on the fouling of a ceramic microfiltration (MF) membrane was studied. AOM alone resulted in a significantly greater flux decline compared with Suwannee River humic acid (HA), and fulvic acid (FA). The … WebTo backwash the membranes, the air is introduced at the bottom of the membrane, and water and air move upward, causing vibration and friction to the membrane. The … WebEquation 9 reveals that backwash flux (J b) has no effect at all on ΔTMP and thus allowing a significant model reduction when compared with Eq. 7.Furthermore, taking into account the standard deviation of the estimation errors, only B f has a pronounced effect on ΔTMP.
