Dielectrophoretically intensified cross-flow membrane filtration

Predicting and eliminating Joule heating constraints in large dielectrophoretic IDE separators

“…Further it risks short circuit and human electric shock (Du et al, 2009). Therefore, an insulation coating on metal electrodes is crucial to prevent from the abovementioned problems in an aqueous DEP system (Cummings and Singh, 2003).…”

Assessment of the Effect of Dielectrophoresis (DEP) on the Viability of Activated Sludge Biomass

“…Many studies have focused on the use of electrophoresis, this is usually associated with the assumption that the bioparticles are negatively charged, however the feed suspension complexity inhibits the use of such an assumption [8], [9]. In addition, direct current (DC) electric field is often used to generate EP which induces higher energy consumption.…”

“…DEP has gained wide utilization in many nanoscale biological applications. In the wastewater industry, it was used by Du et al and Hawari et al, [9], [11] to suppress fouling in membrane treatment processes. Upon the application of dielectrophoretic forces to wastewater, a net repulsive force is created that causes the migration of particles away from the membrane as a result of the differences in permittivity between the medium and bioparticles.…”

A fouling suppression system in submerged membrane bioreactors using dielectrophoretic forces

“…Thus, the electrodes should be designed in a proper way in order for these particles to move in the direction away from the membrane, thereby increasing the permeate flux by reducing the fouling. As mentioned before the main advantage of the DEP force is that it would influence all particles in suspension regardless of their charge (Du et al, 2009). In addition, an agglomeration of particles in the biological wastewater reactor often occurs.…”
