PMA explains why gravimetric laboratory results and UV fluorescence trends can differ, and how to compare them using representative samples.




UV fluorescence is the best available technology for measuring oil in water, especially so when measuring low levels of oil contamination such as in wastewater discharges, cooling water and steam condensate contamination and in intake protection applications.

Many industries require cooling water to transfer heat from the process out of the system. The cooling water must be then be cooled down and discharged before being replaced with fresh water.
