Electroosmotic dewatering (EDW) is one of the effective deeply dewatering technologies that is suitable for treating sludge with 55–80% of moisture content. Regarding EDW as the pretreatment process of drying or incinerating, this article investigated the drying characteristics of electro ...

Electrokinetic Dewatering of Sewage Sludge with Fixed and Moving Electrodes: Attenuation Mechanism and Improvement Approach Tony L. T. Zhan1; Xin Jie Zhan2; Yuan Feng3; and Ping Chen4 Abstract: This paper presents a laboratory study on electrokinetic dewatering (EKD) of sewage sludge with fixed and moving electrodes.

Oil sands tailings (mature fine tailing (MFT)) are the final product of oil sands processing and are in the form of slurry with a very low solid content. After sedimentation, due to a low hydraulic conductivity of the tailings, dewatering and consolidating the tailings is difficult. Since electrokinetics (EK) has been successfully applied on dewatering and consolidation of low permeability ...

The strength of electroosmosis is in its independence of pore size, whereas pressure removes the free water from the larger pores rapidly and causes consolidation to occur. Electroosmosis has no intergranular effects, so consolidation is beneficial to the electroosmotic process in that the pores ...

We have developed an electrokinetic process to rapidly stir micro and nanoliter volume solutions for microfluidic bioanalytical applications. We rapidly stir microflow streams by initiating a flow instability, which we have observed in sinusoidally oscillating, electroosmotic channel flows.

Electroosmotic dewatering provides a potentially attractive alternative technique for in situ dewatering. The technique, which involves the application of a potential difference between electrodes and causes the flow of water to the negatively charged cathode, has seen some limited use in civil engineering applications.

The effect of electrokinetic dewatering (EK) on MFT has been studied by Guo and Shang (2014). Moreover, the vacuum treatment on clay has been studied for ...

Electrokinetic stabilization is an environmentally friendly and time efficient method, however, a lack of standard design guidelines draws the attention of the geotechnical engineers away from this method.

Electrokinetic effects play a large role in such separations. In this study, constantvoltage electroforced sedimentation (EFS) is analyzed by use of the Terzaghi model assuming that the electroosmotic properties of the material are constant.
