Nalco Pretreatment Solutions (PTS)Â is a supplier of commercial and industrial ultraviolet (UV) water treatment systems. Our UV purification systems are available in a variety of sizes and configurations to meet the needs of most water purification applications. For applications greater than 500 GPM, multiple UV water systems can be combined in series or parallel to meet the necessary flow requirements.Â
UV light, specifically the 254 nm wavelength, is a powerful disinfectant. The chief advantages of using UV water treatment systems over chemical treatment are:
A UV water purifier is a simple yet effective way to destroy microorganisms in water. A typical UV water treatment system uses an ultraviolet light to kill microorganisms, and may be combined with a water filter to trap these and other contaminants.
Short wave UV and Vacuum UV are able to penetrate the cell walls of microorganisms, and subsequently disrupt the cells in such a way as to prevent them from replicating. Microorganisms that are unable to replicate are unable to cause human infection or create damaging situations for manufactured products or processing equipment.
The primary mechanism by which UV inactivates microorganisms is the creation of Pyrimidine Dimers. These are bonds that are formed between adjacent pairs of thymin or cytosine pyrimidines on the same DNA or RNA strand. Once the dimmers are formed the microorganism is "locked up" and unable to reproduce.
The peak wavelengths for cellular penetration and disruption are in the range of 250-270 nm. This is why low pressure UV lamps with a peak output of 253.7 are so effective for disinfection purposes.
Nalco PTSÂ ONLY sells industrial or commercial UV water treatment systems when they are part of a larger water treatment plant or project.
Nalco PTSÂ is a distributor for Aquafine, Trojan and UltraDynamicsÂ® Ultraviolet water disinfection systems. Nalco PTSÂ offers 254NM UV lights for bacteria control and 185NM UV lights for TOC control.
Nalco PTSÂ can create a complete and efficient ultraviolet water treatment system by using a standard industrial UV light water treatment system customized for your application and installation.
