ANALYSIS OF BATCH ELECTROKINETIC FILTRATION
Filtration under constant D. C. electric field with constant hydraulic pressure, what is termed electrokinetic filtration, was discussed in this paper. Under these conditions it is considered that electrophoresis occurs in the slurry and causes less cake formation, and that electroosmosis occurs at the same time in the filter cake. Therefore, the flow rate of …
Electrofiltration of silica nanoparticle-containing wastewater using
Various laboratory-scale research results have shown that electrofiltration greatly enhanced the filtration kinetics of aqueous suspensions of anatase [7], quartz sand [8], and kaolin [9]. A similar finding was also obtained in a pilot-scale electrofiltration of SiO 2 using a polyamide membrane with a 0.2-μm pore size [10].
Sedimentation and water electrolysis effects in electrofiltration …
A mathematical model was developed to include gravitational sedimentation of particles and electrolytic gas in electrofiltration theory. The model successfully represented electrofiltration data obtained from kaolin suspensions with a laboratory horizontal filter. Electrolytic gas contributed to an increase of 13% in electrofiltration rate.

The results showed that quartz is composed of 99.5% SiO 2 and 0.0038% Al 2 O 3. Quartz suspensions were prepared by adding appropriate amounts of quartz powder into 250 mL distilled water to obtain a solid concentration of 0.32 g/L in suspension. The natural pH value of the prepared suspension was about 4.
