W Always clean the WATA-Standard after use
After each use, rinse the WATA-Standard with clean water. If after several
uses you notice white marks on the WATA-Standard, prepare a solution of 50%
vinegar (or lemon juice) and 50% clean water. Leave the device to soak for
several hours and then rinse it with clear water. Never scrub the titanium plates.
W Precautions
Do not bend the rods of the WATA-Standard or the electrical cables.
W Maintenance and repairs
Do not attempt to make electrical repairs if you are not competent in this
area. Contact Antenna or a specialist who will assist you or refer you to
appropriate services.
4. WATER QUALITY
The initial quality of the water used affects the efficiency of the sodium hypochlorite
production and efficacy of the water disinfection. The main parameters
characterizing the initial quality required for the water are pH and turbidity.
PH
PH is a measure of a solution’s acidity or alkalinity on a scale from 0 to 14, with a
pH of 7 indicating a neutral solution (such as pure water), <7 indicating an acid
solution (such as lemon juice) and >7 indicating an alkaline solution (such as
soap). PH affects chlorine’s ability to destroy microbes and viruses. Based on
World Health Organization recommendations, to effectively disinfect water with
sodium hypochlorite, the water used should have a pH between 6.5 and 8.5. It is
therefore recommended to measure pH.
TURBIDITY
Turbidity measures the opacity of a liquid. Water’s turbidity is caused by the
presence of solid particles in suspension (clay, sand, bacteria, chemical or metallic
residues, etc.) that make the water cloudy. Water with an elevated turbidity could
lead to the formation of undesirable products during the production of sodium
hypochlorite. During the chlorination process, elevated turbidity could diminish
the treatment’s efficacy. Following recommendations in the Sphere Handbook, to
guarantee optimal efficiency in producing sodium hypochlorite and chlorinating
drinking water, the water used should measure less than 5 units of turbidity.
For more than 5 units of turbidity, when the water is mildly turbid (<30 units of
turbidity), a double dose of sodium hypochlorite can be used, and when the water
