The Cold Water Deaeration deseratess water down to a residual oxygen concentration below 5 ppb.At the same time the water is saturated with 2g/L CO2.Optionally it can be cooled down,filtered or sterilized with ultraviolet light.The function of the unit can be monitored and documented by an in-line oxygen analyzer at the outlet of the unit .

   The process is employed in the brewing ,beverage,food and chemical-pharmaceutical industries,wherever water with low oxygen content is required to assure high product quality and stability.

   The system is characterized by high operational reliability,simple functionality and low investments.Due to the carbonization of water ,the unit is especially suitable for the production of carbonated beverages.

Technical  Description

   The water is distributed homogeneously to the structured packing at the top of the column .The CO2 is fed in at the bottom  of  the column .The  water slowly flows  downwards  through the structured packing in counter current flow  to the  CO2.A long and intensive contact between water and stripping  gas is   ensured by  the high –performance  structured packing .CO2  is dissolved  in  the water up  to a level of 2.0g/l and  at the same time  suppresses the oxygen .Optionally ,nitrogen can be used as stripping gas.

   The deaerated water is pumped out of the bottom of the column  with a frequency controlled pump. Optionally the water can be cooled down in a plate heat exchanger by glycol or ammonia .

   Sensors for oxygen , level ,flow and temperature monitor the proper  functioning of the system.

   The unit can be controlled by a local PLC with a touch panel  or by a process control system.

   Designed for high hygienic standards ,all common cleaning agents in the beverage and chemical –pharmaceutical industry  can be used for CIP cleaning.
