phosphate clay suspensions are a by-product of strip mining rendering large land areas unusable for development. electrokinetic dewatering offers the opportunity to reclaim these areas. dr. moghaddam was awarded a $1.6m grant from the the advanced research projects agency-energy (arpa-e) to develop a membrane based absorption cooling system.
a typical florida phosphate mining operation produces more than 100000 gallons/min of phosphatic clay. the suspensions are pumped into large impoundments called clay settling areas (csa) in which separation is achieved by hindered settling and self-consolidation. ... previous research to develop batch electrokinetic dewatering processes ...
study assessed the performance of an enhanced electrokinetic technology which permits the simultaneous dewatering heavy metal removal and inactivation of the swine helminth ascaris suum from wastewater sludge in one operational unit for the production of exceptional quality biosolids.

abstract. a mathematical model is presented for the electrokinetic dewatering of suspensions of phosphatic clays. the modeling approach couples a boundary-element model for solution of laplace’s equation to a recently developed constitutive equation that relates the change in solids content with applied electric field and time.
the florida institute of phosphate research (fipr) has supported bench- and pilot-scale studies to determine the technical and economic feasibility of a variety of processes to speed the dewatering of clays associated with phosphate mining.

the effect of electrokinetic on pore water of the marine clay daniel tjandra lecturer civil engineering department petra christian university paravita sri wulandari lecturer civil engineering department petra christian university abstract high water content on the marine clay will loose the bond of soil particles and its bearing capacity will be decreased.
the use of an applied electric field for dewatering was explored in the late 1990s. electrokinetic separation was found to be promising but the technology was not considered economical. under funding from mosaic a major phosphate mining company our group produced bench-top results similar to those reported in the literature.
