Conductivity is defined as a measure of water’s ability to pass an electrical flow. Ion concentration is the definer as to its conductivity. These ions are in the form of dissolved salts or inorganic compounds, known as electrolytes, that dissolve into ions. On the conductivity spectrum, sea water has very high conductivity while distilled water is a low electricity conductor.
Temperature also impacts conductivity. As it increases, so does conductivity values. Conductivity’s reciprocal, called resistivity, is water’s opposition to a current’s flow and is higher as the ions in the water decrease. Total Dissolved Solids (TDS) are the sum of ionic particles and other solids contained in wastewater. The higher the TDS, the more conductivity is present.
Traditional electrocoagulation methods are impacted by low conductivity more than Thincell. With linear current paths between the closely spaced (½” – 2”) sacrificial electrodes, there is restricted current transmission. When coupled with passivation of the anode and cathode plates, there is an increased power demand and a reduced surface area on the electrodes. This combination makes traditional electrocoagulation largely ineffective with low conductivity waters.
The Thincell electrochemical technology, on the other hand, incorporates proprietary non-passivating anodes and cathodes widely spaced (6” minimum). Using sacrificial bi-polar electrodes that are separated from the water molecules, a conductivity bridge forms that is more efficient even in a low conductivity fluid environment. In extreme cases of low conductive fluids, salt might need to be added but can be safely removed with additional processing.
