Vacuum enhanced stripping technology for deaerated water production
- Final oxygen below 10 ppb
- Very low CO2 or N2 consumption
- Efficient and hygienic design
The deaeration column is filled with high efficient structured packing. Its large internal surface ensures a maximal contact area between gas and li quid. Water is homogeneously distributed on the top and CO2 or N2 is injected at the bottom of the column. While the water flows downwards through the packing, the CO2 or N2 rises in counter current removing the oxygen to concentrations as low as 10 ppb. The deaeration column operates under vacuum, decreasing gas solubility in water. Therefore striping gas consumption is significantly lower compared to the unit working under atmospheric pressure.
The unit has an uncompromising sanitary design and is fully CIP cleanable. A drive controlled pump maintains the level in the column and forwards the deaerated water into a buffer tank or point of use.
