Practical UV Light Source Diagnostic Tools for Measuring Uniformity, Intensity and Fluence

摘要

Industry leaders within the UV disinfection marketplace and the customers, who purchase their systems, understand that the majority of costs to a water treatment facility is spent on system maintenance and is typically the largest single controllable expenditure in a production plant. Reducing costs in this economy is a driving factor, towards improving in-situ predictive and proactive, not reactive maintenance of UV based water treatment and industrial disinfection systems. With practical and cost effective diagnostic tools UV disinfection system developers can develop further proactive approaches to reduce system down time, safe guard operational performance and reduce premature or catastrophic failures during plant operations. A critical aspect of UV disinfection systems is that it is the last line of defense for making water and air safer to the general population. Analytical analysis (computational) provides quantifiable results on performance that are more precise than qualitative standards, but each have a role in determining overall performance of the system when taking into consideration issues or variables that tend to emerge within a dynamic and operational system. This paper highlights the need for alternate diagnostics to cover variables that can not be factored into the analytical analysis. The paper will provide an overview of potential diagnostic tools which could be used during research, design and manufacture of UV reactors and by the end customer or field service engineers to diagnose problems or monitor key process performance indicators.
