Concerning the electrokinetic and retentiondrainage tests Table 1 presents zeta potential and dewatering properties for the fibrous materials analyzed in study.
tailings dewatering techniques. An alternative solution consists in dewater and consolidate mine tailings under current intermittence, technique called electroosmosis. This paper presents the development of an electroosmotic cell to measure the electrokinetic flow and the consolidation process of fine tailings under specified boundary conditions.
Mar 09, 2011· Kurita developed this system by applying its unique sludge dewatering technology. The system first charges sludge with electricity to generate an electroosmotic flow. It then uses the flow and pressure generated to move solids to the positive electrode and water to the negative electrode, thereby effectively dewatering the sludge.
Electrokinetic treatment has been known in geotechnical engineering for over six decades, yet, the technique is rarely used. This stems from the absence of design guidelines and specifications for electrokinetic treatment systems.
Electrokinetic sludge dewatering is one of the most innovative sludge dewatering technologies in the world. It is distinguished from other conventional dewatering technologies that remove only the free water in a liquid/solid suspension to achieve a dry solid content DS 25~35% using conventional devices such as belt press, centrifuge or filter press.
Abstract: Saturated soft soils can be strengthened by several methods such as dewatering or adding suitable chemicals. Introduction of chemicals through electrokinetic (EK) process to strengthen a residual soil was investigated. The results of chemical tests on an .

This report describes Bureau of Mines laboratory test results in electrokinetic dewatering and consolidation of metalmine tailings. Tailings were placed in plexiglass models, and DC potential was applied until dewatering ceased.
Malekzadeh, M., and Sivakugan, S. (2016) Assessing the use of aluminium electrodes on the electrokinetic dewatering and stabilization of dredged mud slurries. In: Selected Papers from Sessions of GeoChicago 2016. pp. 188202.
Aug 03, 2017· Electrokinetic geosynthetics enable civil engineers to put electrical energy into the ground to stiffen it and control groundwater flows. This paper summarises the evolution of the technology over the past 25 years, from research by way of hype and into practice.
1 Effect of Electrical Conditions on the Efficiency of Electrokinetic Drainage Geocomposites for Tailings Dewatering Patricia I. Dolez1*, Eric Blond2 and Pascal Saunier3 1. SAGEOS / CTT Group, CTT Group, StHyacinthe, QC, Canada, pdolez
This is probably due to the high energy costs reported in the literature, as well as problems of very rapid corrosion of metal electrodes. This paper describes a study using newly developed electrokinetic geosynthetics (EKGs) as electrodes for the in situ dewatering of mine tailings.
Electrokinetic Geosynthetics from research to applications Presented by: Colin Jones Authors Scope What are ElectroKinetic Geosynthetics (EKG)? Electrokinetic phenomena Benefits and Drivers (why develop EKGs) Nature and forms of EK materials Where research – applications are active Examples of current research and developments ...
Electrokinetic remediation (EKR) is one of the effective insitu technologies for remediation of contaminated sites with inorganic contaminants, organic contaminants, or combination of .
2 Electrokinetic Method The surface tension in a liquid can be calculated using equation 1: In which, is surface tension, is binding energy in a molecule, L mol is the distance between molecules, h is the specific heat of evaporation, m is the mass of a single molecule and is the density of molecules. Young presented
Jun 09, 1987· The present invention relates to the dewatering of sludges, slurries, or the like, that contain macromolecules, colloidal particles, and/or suspended particles in a carrier liquid, usually water, and, more particularly, to dewatering of such materials using electrokinetic techniques including both electrophoretic and electroosmotic techniques.
Electroosmotic flow is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane, microchannel, or any other fluid conduit. Because electroosmotic velocities are independent of conduit size, as long as the electrical double layer is much smaller than the characteristic length scale of the channel, electroosmotic flow will have little effect. Electroosmotic flow is most .
