Issues which can affect the water quality of RO systems
Xsential warrants that its reverse osmosis systems will reject up to 92-96% of salts in water.
The reverse osmosis (RO) technology has been around for many years and has shown that the technology provides
the best solution when it comes to the protection from scaling of water feed appliances. Such appliances include
combi-steamer ovens and coffee machines.
The use of RO systems have also been known to contribute to the extension of life of water feed appliances.
However, RO systems cannot prevent corrosion from occurring. RO systems will invariably remove the elements in
water that could contribute to corrosion thereby prolonging the life of appliances but corrosion can commence in any
number of ways.
All corrosion issues should be investigated by a corrosion expert.
Below are some factors which can affect the warranty and performance of our RO systems.
1. Water source: Australia’s water can come from dams, underground wells, desalination plants, or a mixture
of various sources. This results in an inconsistent quality of water whereby some water sources could have
more dissolved salts than others. For example underground sources of water have more dissolved salts than
water from a dam. Hence RO systems might not be suitable for use in some areas. Highly saline water can
affect the performance of Xsential’s RO systems. Please check the water quality with your local water
authorities.
2. Seasonality:
The concentration of salts in water increases in some seasons due to lack of rainfall while in
other seasons, the water may be less saline.
3. Chemical treatment:
The amount of chemicals used to treat the water e.g. chlorine, fluoride, etc can lead
to inconsistencies in the water quality. Water is treated periodically by the local water authority leading to
times when the water may contain high doses of elements that can cause corrosion.
4. Manufacturer’s water requirements:
The requirements by individual water feed appliances such as combi
steamer ovens may vary from the specification produced by Xsential’s RO systems. The end user should be
made aware of this.
5. Wrong
installation.
6. Wrong TDS/water hardness output adjustment.
7. Service interval: it is very important that all of Xsential’s RO systems are serviced regularly. Failure to
service (replace filter cartridges) regularly can cause the RO system to not function properly. See the
installation manual for details.
Although all care has been taken by Xsential to ensure that its RO systems perform according to its manufacturer’s
specification, Xsential cannot guarantee the performance of its water treatment systems due to factors which are
beyond its control. Some of these factors have been listed above. End users should be made aware of the factors
that could affect the life of water feed appliances.
