The first documented
use of silver with persulphates to control bacteria
in swimming pools was reported in 1970 and used successfully
by Marotta Scientific Controls Inc. New Jersey, U.S.A.
The persulphate was utilised to maintain the silver
in an oxidised state. Silver ions were added to the
pool in the form of silver nitrate (Zsoldos and Kowalski,
1970).
The Aquabrite system is capable of controlling algae
and bacteria to within safe limits in both swimming
pools and spas, including herbal spas. Laboratory
tests under controlled conditions confirm its efficacy*.
The Aquabrite System has been applied by the Warringah
Shire Council successfully to a fountain at the Warringah
Mall Shopping Centre, Brookvale. A decorative water
cascade at the AMP Centre, Circular Quay also used
the system. A 55 metre resort pool ,Trinity Links,
Cairns successfully uses The Aquabrite System. Hundreds
of domestic pool owners in Australia and overseas
have adopted the system.
The applications are numerous and the system virtually
unlimited in scope. A trial of the principle in a
domestic swimming pool situation was conducted over
a period of four months from November 1990 to March
1991 with successful results. The pool, located at
Seaforth, Sydney continues to be operated on the system
to the present time. No chlorine or bromine has been
used since the system was installed. In July 1995
an Aquabrite system was fitted to a commercial herbal
spa in a Korean hotel and bathhouse at Kings Cross,
Sydney. Subsequent monitoring by both South Sydney
Council and an independent N.A.T.A. registered laboratory
demonstrated that the bacterial quality of the spa
water complied with regulations contained within the
Public Health Act, 1991. Two additional systems have
since been installed in the same hotel.
· Laboratory efficacy studies were conducted
from February to April 1991 at the NATA registered
laboratories of Judell Platt Thomas and Associates.
Results confirmed that the method was an effective
disinfectant and that the treatment remained active
for a period of several weeks after the water had
been treated.
The Aquabrite System may be considered as a viable
option wherever algae and bacteria pose a problem
in fresh water. It is especially valuable as an alternative
to chlorination in cases where a medical condition
such as dermatitis or an allergy to chlorine or chlorinated
compounds would prevent the pleasures of swimming.
The system is particularly useful for the treatment
of pool water which may be discharged into environmentally
sensitive areas.
