INSTALLATION PRINCIPLE

EKOGRID™
INSTALLATION PRINCIPLE OF THE GRID AND TRANFER PULSE

  • Cost effective installation of electrodes and cabling 

  • ​​Low energy consumption 

  • Perforated pipe can be used as electrodes and as an injection point for  bio-remidiation agents, as well as water sampling points

  • Electrode spacing typically 5 m

  • Pulsed current goes through polluted soil (marked reaction paths), and  oxidizing chemicals are formed by electrochemical reactions at particle    surfaces

  • EKOGRID™ transfer pulse can transport water and water soluble  compounds in the soil and groundwater between the electrodes

EKOGRID™ Electro Osmotic Transport

  • In normal remediating mode EKOGRID™ pulses are equally timed to both directions between the electrode rows

​​

  • The low voltage current makes the charged contents of the pore water move back and forward with short electro-osmotic pulses

​

  • EKOGRID™ control unit can be used in transfer mode, where longer pulse to one direction is applied

​

  • Transfer mode utilizes electro-osmosis to move soil cations and water with everything water soluble

​

  • •Water and nutrients pumped via electrodes, optimally to every second electrode row first and then to the other rows

​

  • •When injecting (water and nutrients pumped to tubular electrodes) EKOGRID™ electric field is adjusted for transfer pulse (e.g. 6-24 hours with longer pulses to one direction)

​

  • •When not injecting the normal symmetric EKOGRID pulse for induced electrolysis is used.

  • DRAWING B – Drill tube electrodes with perforation both in unsaturated and saturated zone

​

  • •Same as in option A, but injection system extended to the unsaturated zone

​

  • •Solution is recommend if targeted contamination is mostly in both saturated and unsaturated zone
