What is role of CO2 breather arrangement in DM storage tank?

Answer 1

High quality of DM water is important for such industries as power generation, semiconductor and pharmaceutical where there are strict regulatory requirements.

The most common way to measure very low levels of ionic impurities in ultra pure water is on line analysis of conductivity and resistivity. DM water is often exposed to CO2 from the air, which increases its conductivity and gives the appearance of a contaminant in the water. Depending on CO2 concentration in incoming air water conductivity can be increased to ~0.8-1.5 µS/cm.

CO2 breather or CO2 Scrubber for DM Tanks allows you to keep stable pH and low conductivity of DM water.
