13 The conductivity of the water
Conductivity is a measure of water’s capability to pass electrical flow. This ability is directly related to the
concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials
such as alkalis, chlorides, sulphides and carbonate compounds. Compounds that dissolve into ions are also
known as electrolytes. The more ions that are present, the higher the conductivity of water. Likewise, the
fewer ions that are in the water, the less conductive it is. Distilled or deionized water can act as an insulator
due to its very low (perhaps negligible) conductivity value.
Conductivity drinking water 100 to 500 µS/cm
Distilled or deionized water 0.5 to 5 µS/cm
If the EK-X/24 is to be installed in a low conductivity application (see chapter 8 Technical data), the flowrate
of produced water will be very much lower compared to normal drinking water and different sized cathodes
will be required consisting of a central cathode with a larger diameter (50mm) and an outer cathode with
a smaller diameter (110mm). This results in a reduction of the distance between the electrodes that an
electrical current needs to pass through.
