Carbon dioxide is a common cause of the high conductivity. Membrane contactors remove carbon dioxide from water, typically upstream, without a chemical pH adjustment, allowing EDI and CDI systems produce higher quality water. Another postive side-effect is that Silica and Boron outlets in the EDI/CDI units improve CO2 is not present. (read more)
