  • Electrokinetic Dewatering Methods

    Electrokinetic has developed a wide range of EKG materials combining electroosmosis and filtration to yield an enhanced dewatering performance. This in turn offers improvements in performance (increase in solids content of dewatered material) or an increase in the speed of dewatering to the extent that filtration dewatering of some especially difficult materials becomes viable.
