Deaerated water is used in the brewing industry for flushing filters, centrifuges, pipes, tanks etc. When used to adjust alcohol concentration or original gravity after filtration, residual oxygen concentration of the deaerated water is critical as it directly influences the quality and shelf life of the final product.
Designed for most efficient deaeration of water, DENWEL provides a fully automated solution able to economically achieve oxygen levels below 10 ppb.
The deaeration column is filled with high efficient structured packing. Its large internal surface ensures a maximal contact area between gas and liquid. Water is homogenously distributed on the top and CO2 is injected at the bottom of the column. While the water rinses downwards through the packing, the CO2 rises in counter current stripping the Oxygen out 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.
This technology is distinguished by high efficiency and reliability and consumes just a fraction of energy compared to other methods.
The unit can be extended with inline Oxygen Analyzer, Cooling, Pre-Carbonation, UV Sterilisation, and integration of a storage tank.
