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 gpg (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 less than 7 gpg, the UV unit should operate
efficiently provided the quartz sleeve is cleaned periodically. If total hardness
exceeds 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.
