Soft water Hard
water, and especially water containing a high level of carbonates,
contains mainly those hardness constituents that accumulate in the pool
water circuit as limescale deposits when the water is warmed. The same
applies here as in the use of water in the modern household: at
carbonate hardness levels of 10-12 °dH and more, the use of a
water-softening system is recommended. The
JUDO protection filter prevents the ingress of dirt particles. The JUDO
softening system produces the required water hardness. The JUDO JULiA
dosing pump system provides corrosion protection for the domestic
piping system. Such protection is not required in the swimming pool
circuit. The freshwater filling pipe to the swimming pool therefore
branches off after the JUDO softening system, but before the JUDO JULiA
dosing pump system.
Water care In
addition to the JUDO disinfection range (JUDO Liquid Chlorine, JUDO
Chlorine Granulate, JUDO Chlorine Tablets, JUDO Bromide Sticks and JUDO
Active Oxygen [granulate or liquid with dosing pump]), JUDO also
supplies products for pH-level correction and flocculation. Once
the carbonic acid in the swimming pool circuit, which has a major
influence on the pH-level of the water, escapes more or less quickly
into the atmosphere, the pH-level usually increases. In order to
prevent this, and keep the pH-level within acceptable limits (ideally
between pH 7.2 and 7.4, max. between pH 7.0 and 7.6), JUDO pH-Minus is
added. If the pH-level falls below the lower limit, JUDO pH-Plus must
be used. The water disinfection works best within these limit values.
The effectiveness of the disinfection can be checked by measuring the
redox potential. Dosing can also be controlled automatically for this
purpose.
What is flocculation, and when is it recommended? A
distinction must be made between flocculation for the purposes of
precipitating out dirt in the pool (with the filter system switched
off), for example if the balance of the water has been "tipped over"
due to faulty system maintenance or severe outside influences, and
flocculation before the filter in heavily contaminated pools in order
to remove dispersed colloidal impurities (solid clouding materials of
either organic or inorganic nature), which can only be brought into a
filterable state by flocculation. JUDO LIBELLE filter systems provide a
filtration effect that makes the dosing of flocculation agent
unnecessary with normal water care and in a private swimming pool
subjected to average contamination.
Specially important The
carbonate hardness: this should never be allowed to fall below 3 °dH,
since this will cause the pH-level to fall into the corrosive mineral
acidic range. A JUDO carbonate hardness testing device is therefore a
"must" for every swimming pool.
Checking the water quality In
addition to various other testing devices, JUDO offers a convenient,
reliable and automatic system for control and checking of dosing
systems in the form of the JUDO LIBELLE Pool-Controller. In combination
with suitable dosing systems and ingredients, the system carries out
measurements continuously, adjusting the dosing as required. A
technique which is today the norm in public swimming pools (despite
continual specialist supervision), and is also being used more and more
in private pools.
