A brief introduction to the
Diamond Spring REVERSE OSMOSIS
(R.O.)
point of use equipment for correction
of drinking water quality
Reverse Osmosis is an adaptation of nature’s
biological process. In the reverse osmosis process water is
forced through a semi-permeable membrane that separates out
the impurities and rejects them to the household drainage
system. The R.O. membrane deals equally with bacteriological,
chemical, organic and non-organic contamination. It will remove
up to 98% of all pollutants.
In humans, fluids pass in and out of such membranes
(cell tissues) by the phenomenon known as osmosis, while plants
absorb food and moisture from soil in the same way. Reverse
osmosis is simply this natural process turned around.
The Diamond Spring R.O.
purification equipment is suitable for use on water supplies
from mains water supplies which may be subject to pollution
problems. Other consumers may be interested who suffer from
specific medical conditions, e.g. kidney sufferers, for whom
the equipment is strongly recommended.
Reverse Osmosis (R.O.) is generally recognized
as being the only really effective form of purification which
can offer a solution to a wide range of problems, from the
bacteria, excess salts and heavy metals which affect private
water supplies, to the problems arising from industrial effluent
and intensive farming which can pollute even municipal supplies.
Diamond Spring R.O.
purification combines reverse osmosis with two other forms
of treatment. Firstly, the water passes through a dirt/sediment
filter. This removes particles and protects the next stage,
the R.O. membrane, helping to extend its serviceable life.
Then the product water from the R.O. membrane passes through
a granular activated carbon filter, which is particularly
effective against organic chemicals, this guarantees that
the water tastes good. Thus the three stage process is capable
of dealing with any problem.
The Diamond Spring R.O.
purification equipment is guaranteed to meet EEC Directives
on both maximum admissible concentrations and guide levels
for pollutants in drinking water.
Here are some results from the American Testing
Institute of San Diego, California on R.O. membranes which
show just how effective R.O. systems are.

Your questions answered
1. How good are
R.O. Systems?
With the Reverse Osmosis method,
all but about 5-10% of pollutants, (dependant on the type
of membrane used and other parameters) even those that are
dissolved in solution are extracted by the membrane and passed
to household drainage system.
2. What does
Diamond Spring R.O. Water taste like?
Diamond Spring R.O. systems,
using no chemicals or additives, produce clear polished water
that tastes light and pleasant. It is what our customers comment
on, when asked what they like most about their own water purification
equipment.
3. What about
the minerals in tap water?
Independent medical advisers
in the United Kingdom tell us that virtually all of the trace
elements and minerals that we need can be supplied in a well
balanced diet, and can not be found in a balanced
and wholesome form in the water we drink from the tap.
A naturally occurring mineral in water is calcium carbonate
(CaCo2) which, if present in large quantities,
will fur up your arteries as well as your kettle.
We believe that the minerals in tap water are of little use,
having been mixed up with the wide variety of pollutants now
found in water supplies. We suggest a catalytic mineral concentrate
in liquid form, developed by Drs Patrick and Gael Flanagan
and called Crystal Energy.
4. What makes
Diamond Spring's R.O. system
so different?
In the process of removing the
dissolved solids with any R.O. membrane system, the pH of
the product water can lower and become more acidic. In the
Diamond Spring R.O. system, a special pH balancing media in
the form of Coral Calcium (CaCo3) is used to overcome
this problem. A silica media may also be used in the system
to ‘energize’ the water and introduce a trace amount of mineral
into the purified water.
5. Why is a granular activated carbon also
included?
Its main purpose is to ensure
that your purified water is pleasant to taste.
6. Will the system
produce enough pure water?
Yes, the standard R.O. system
will produce between 10 to 15 gallons of pure water each day,
more than enough for the average family. Other models produce
more - up to 20 plus gallons per day and systems can be made
to order that will produce up to 120 gallons.
7. Will it take
up much space?
No, the undersink system measures
just 45cm high, 33cm wide and 13cm deep. It will fit into
most undersink or other kitchen cabinets without difficulty.
The reservoir is 45cm high and 28cm diameter.
8. Will it need electricity?
Not usually, unless the mains
pressure is particularly low. Then a special booster pump
is required and a power supply.
9. What is the 'auto shut valve' for?
This is the pressure activated
control valve that ensures the plant is automatically shut
off when the reservoir is full.
10. What is a ‘flush valve’?
This is a valve that is periodically
opened to flush away any accumulated deposits and debris from
the membrane.
11. What will it cost to run?
The only running costs arise
from the replacement of the two filters every six months.
The reverse osmosis membrane will last approximately 2/3 years
(more frequently if the feed water is of exceptionally poor
quality, possibly less frequently if a water softener has
been installed). The cost can be as low as £2 per week, or
just 6 pence a gallon of pure water, depending on usage and
location, surely very good value when you consider what is
being achieved by the system.
12. How do I
get the system installed?
Your Diamond
Spring Distributor will arrange the installation
for you. This work will take approximately 1-2 hours, longer
if there is exceptional plumbing work.
Your Distributor will then send
you a reminder at 6-month intervals to ensure that the filters
are replaced. The Distributor, who will carry out this work
for you, will at the same time check that the system is functioning
correctly and will carry out all appropriate servicing.
