2.5.3 Reverse Osmosis
A Reverse Osmosis (RO) system may be used to improve the quality of the water
used to generate steam in the autoclave chamber.
In RO, the water is forced through a semi-penetrable membrane, which filters out
contaminants to a high degree of efficiency. In deionisation (DI) ions and charged
particles are removed either by electric fields or by ion exchange in resin beds.
Although the RO cannot normally attain the degree of purity possible with the DI
methods, it is more than adequate for the feed water intended for clean-steam
generators.
Moreover the RO has several advantages:
1. RO is cheaper to install and to run than DI.
2. RO removes particulate matter, organic molecules and pyrogens that DI
cannot remove
3. RO water is less corrosive to steel and copper than DI water.
4. RO maintenance requirements are less demanding than those of the DI
units.
Therefore the use of mineral free water will contribute to better performance and
longer life of the autoclave.
NOTE!
Please consult a water specialist
