As water percolates through the ground it invariably
dissolves some minerals, and it is these minerals
that we find on our windows and our cars after
we washed with tap water these come in the form
of white streaks and spots etc. after the water
has evaporated.
As window cleaners we usually remove the water
with a squeegee. |
If the dissolved solids could be removed
from the water before the cleaning process,
then this would inevitably remove the problem
of streaking, and that is what the pure water
fed poles systems strives to do.

| There are three
main stages of water purification: |
|
|
|
Water Softening
If your water is hard you
will need the water softener (T.D.S. reading
150+)
This swaps the calcium and magnesium, which
makes the water hard, for sodium, which is obtained
from common salt.
We have found in our experience
that this stage can be eliminated if desired,
although it can be fitted to costumer requirements. |

R.O. (Reverse Osmosis)
The next stage, Reverse Osmosis, is the most
important. It involves the pre-filtration of tap
water by removing particulates, down to the microns
and the removal of chlorine. The RO membranes
hate it, and damage will be caused if not undertaken.
So the tap water is first of all pre-filtered
with a sediment filter and a carbon filter then
under pressure passed over the synthetic membrane
were the pure water is piped over to storage and
the waste with the impurities carried off to drain.
By means of this method some 90-98 % of impurities
can be removed.

|
Di-Ionising
Water is pasted through a small polishing
vessel of two synthetic deionising and demineralising
resins.
The water is then passed through the D.I.
resin vessel where it is polished to pure water
ready to be tanked and used. Using the T.D.S.
meter can check the final purity of your water.

|
| And
so we developed...
With the uptake of this method in window cleaning,
there are now systems that can suit even the
smallest of businesses.
That is why we have developed what is known
as the commercial and the residential systems.
|
What
is your next step?
Well why don’t you give us a call and
discuss your needs and we can advise on what
may be best for you now and into the future.
We will be up front honest and give you the
benefit of our experience. |
