Quartz Sleeve Condition
Materials (dirt, waste, bioflocculant, plant material and
scale) all absorb UV light. The more material on the quartz
sleeve the greater UV absorption. The result: reduced UV
performance. For quartz sleeve cleaning instructions See
Page 32.
UV Lamp Performance
A UV lamp degrades over its operating life thus explaining why Pentair
Commercial Aquatics suggests water flow-rates for our Bioshield™ UV
Disinfection System based on "end of useful lamp life" performance. Your
UV System is designed to utilize its lamp's UV-C output to their maximum
potential and should not be modified. Lamps reaching the end of their
useful life should be changed-out. UV lamps that are operated past their
"end of useful lamp life" can reduce the ballasts operating efficiency.
Ballast Performance
The ballast/power supply must be sized appropriately to the specific "input watt" requirement of the UV lamp. Under-driving
the lamp will result in diminished UV-C output while over-driving the lamp will result in reduced "useful lamp life".
Water Flow Rate
The "flow rate" must consider all critical operating criteria for the specific UV system combined with the intended
applications percent UV transmissibility (%UVT). Each model UV system and application is unique and therefore must be
calculated independently.
UV System Design
Your UV system is designed and manufactured to deliver many years of dependable operation. The UV system is unique
and designed to utilize its UV lamp's output to their maximum potential. We combine critical performance criteria including:
UV lamp output, power supply performance and lamp array. We use the Bolton Photosciences "UV CALC Modeling
Program" to verify each UV system's operating capacity. The Bolton Photosciences UV CALC Modeling Program is
recognized by the United States Environmental Protection Agency (EPA).
