Why do UV lamps need quartz sleeve?
A quartz sleeve protects the UV lamp from the water because water and electricity don't mix well. One or two O-rings to seal the whole system together. UV lamps run on mercury vapor. The mercury vapor is loaded into a UV lamp in the form of little beads. Occasionally, you may see beads rolling around in the lamp.
HOW ULTRAVIOLET UV-C WATER TREATMENT WORKS?
THE DIFFERENT TYPES OF UV-RAYS There are several categories of ultraviolet rays depending on their wavelengths measured in Nanometer (nm). The UV rays’ wavelengths start from 10nm (under it’s X-rays) to 400nm (beyond it’s visible radiation).
THE EFFECTIVE UV DOSE
The effective UV dose, expressed in mJ/cm² (millijoules per square centimeter), refers to the necessary UV energy that the micro-organisms (bacteria, viruses, algae in suspension…) must absorb before being destroyed.
UV Radiation (How it Works)
UV radiation affects microorganisms by altering the DNA in the cells and impeding reproduction. UV treatment does not remove organisms from the water, it merely inactivates them. The effectiveness of this process is related to exposure time and lamp intensity as well as general water quality parameters.
