The water is distributed homogeneously to the structured packing at the top of the column. It slowly flows downwards through the structured packing. An excellent distribution of the water in the column is ensured by the high-performance structured packing. The resulting enlargement of the contact surface of water causes an optimal removal of oxygen. Due to the combination of two degassing steps operated at different pressures, lowest oxygen values are reached.
No stripping gas is used and zero greenhouse gas is emitted. 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.
