The deaeration column is filled with high-efficiency structured packing. Its large internal surface ensures a maximal contact area between gas and liquid. Water is homogeneously distributed on the top and CO₂ / N₂ is injected at the bottom of the column. While the water flows downwards through the packing, the CO₂ / N₂ rises counter-currently, removing the oxygen to concentrations as low as 10 ppb. A drive-controlled pump maintains the level in the column and forwards the deaerated water into a buffer tank or point of use. 

The unit has an uncompromising sanitary design and is fully CIP cleanable.
