Oxygen Scavenger Filter

The reaction product Fe(OH)₃ is a soft, flocculent material. When it accumulates to a certain extent, backwash water is introduced to flush it away, restoring the initial deoxygenation capacity. This working principle is the same as the traditional steel scrap deoxygenation method. However, since sponge iron is produced using patented technology to form a loose, porous granular material, its surface area is 50,000 to 100,000 times that of ordinary steel scrap. This overcomes the shortcomings of steel scrap deoxygenation, such as unsatisfactory results and the need for periodic acid washing and activation, achieving a simple, practical, efficient, and stable deoxygenation effect.

Main Features:

1.  Deoxygenation at room temperature without heating, overcoming the energy consumption drawbacks of thermal and vacuum deoxygenation methods;
2.  Highly efficient and stable, with effluent quality meeting national standards for low-pressure boiler water quality;
3.  No special installation requirements, overcoming the inconvenience of high-level installation for thermal and vacuum deoxygenation;
4.  Two control modes: manual and automatic, selectable by the user;
5.  Simple system, compact equipment, and small footprint.
