uvAQUAFINEUV Technology

The Science of Ultraviolet Light

Light is electromagnetic radiation, or radiant energy traveling in the form of waves. Ultraviolet (UV) energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. The energy employed for UV water treatment is further categorized into two primary levels measured as wavelengths - 254nm and 185nm, where nm = 1/1000 of a micron. For disinfection and ozone destruction applications, the 254nm wavelength is utilized. For TOC reduction and chlorine destruction applications a unique wavelength is utilized. 

 

 

The UV light penetrates the outer cell wall of the microorganism, passes through the cell body, reaches the DNA (deoxyribonucleic acid) and alters the genetic material. The microorganisms are thereby destroyed in a non-chemical manner (Figure 1). The 254nm UV light is also used to destroy residual ozone present in a water stream. The 185nm UV light, utilized in TOC reduction applications, decomposes the organic molecules. The 185nm light carries more energy than the 254nm light. The 185nm light generates hydroxyl (OH·) free radicals from water molecules.

 


The use of UV technology for water treatment has several inherent advantages. UV light does not ‘add’ anything to the water stream such as undesirable color, odor, chemicals, or taste, nor does it generate harmful by-products. It only imparts energy to the water stream in the form of UV light to accomplish the process of disinfection, TOC reduction, ozone destruction or chlorine/chloramine destruction. UV disinfection produces no residual disinfectant to the finished water.

uvAQUAFINE UV systems feature low pressure mercury discharge lamps. The lamps are constructed with a special quartz envelope material that looks like glass, but is actually a discriminating filter. This exclusive design allows predominantly 254nm or 185nm UV energy to be transmitted into a water stream as it flows through the UV system's treatment chamber. The primary uses of UV for water treatment are: disinfection, TOC Reduction, ozone destruction and Chlorine Destruction.
