Attention:
We recommend testing the water quality once a month. The use of
water for autoclaves that do not comply with the table above may
have severe impact on the working life of the sterilizer and can
invalidate the manufacturer’s guarantee.
3.11.2
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.
