WATER CHEMISTRY
Water quality is extremely important for the optimum performance of your UV
system. The following levels are recommended for installation:
• Iron:<0.3 ppm (0.3 mg/L)
• Hardness *:< 7 ppm (120 mg/L)
• Turbidity: < 1 NTU
• Manganese: < 0.05 ppm (0.05 mg/L)
• Tannins: < 0.1 ppm (0.1 mg/L)
• UV Transmittance: > 75%
(Call factory for recommendations on applications where UVT < 75%)
* Where total hardness is more than 7 gpg, the UV unit should operate efciently provided the
quartz sleeve is cleaned periodically. If total hardness is over 7 gpg, the water should be softened.
If your water chemistry contains levels in excess of those mentioned above, proper
pre-treatment is recommended to correct these water problems prior to the installation
of your UV disinfection system. These water quality parameters can be tested by your
local dealer, or by most private analytical laboratories. Proper pre-treatment is essential
for the UV disinfection system to operate as intended.
