“…The anodes used for electrofiltration are often constructed from titanium meshes coated by either mixed metal oxides (Citeau et al 2012;Raats et al 2002) or noble metals (Rabie et al 1994;Saveyn et al 2006) in order to prevent corrosion (Larue et al 2003). The electrolysis reactions at the cathode are:…”

One of the main challenges for industrial production of cellulose nanocrystals is the high energy demand during the dewatering of dilute aqueous suspensions. It is addressed in this study by utilising electroosmotic dewatering to increase the solid content of suspensions of cellulose nanocrystals. The solid content was increased from 2.3 up to 15.3 wt%, i.e. removal of more than 85% of all the water present in the system, at a much lower energy demand than that of thermal drying. Increasing the strength of the electric field increased not only the dewatering rate but also the specific energy demand of the dewatering operation: the electric field strength used in potential industrial applications is thus a trade-off between the rate of dewatering and the energy demand. Additionally, it was found that high local current intensity had the potential of degrading cellulose nanocrystals in contact with the anode. The maximum strength of the electric field applied should therefore be limited depending on the equipment design and the suspension conditions.

“…Among the electrochemical technologies, electrocoagulation and electroflotation may be effective substitutes for conventional coagulation and flotation 6 . Also electrocoagulation/electroflotation has been reported to successfully treat different kinds of wastewater, containing oil, 8 fluoride, 9 arsenic, 10 dyes, 11 -16 suspended particles, 17 chromium ions 18 and phosphate. 19,20 The removal of arsenic by electrocoagulation using a combined Al-Fe electrode system was investigated by Jewel et al 21 Observation of the substitution of Fe 3+ ions by Al 3+ ions in the solid surface indicates an alternative mechanism of arsenic removal by these metal hydroxides and oxyhydroxides by providing a larger surface area for arsenic adsorption by retarding the formation of crystalline iron oxides.…”

“…Usually, the electrodes used in electrofiltration are made from insoluble materials (such as precious metals, conductive ceramics). However, in case soluble anodes are used (such as aluminum or iron), anode electrolysis generates ions that can be very effective in the coagulation of the suspended particles (Larue et al, 2003). The coagulation effect induced by pH or by other electrolytic products may increase the filter cake permeability and help the filtration process.…”
