OPTIMIZED UV TREATMENT FOR MICROELECTRONICS
Total Organic Carbon (TOC) is found in all water supplies as naturally occurring organic matter. In order to produce ultrapure water for use in microelectronics applications, TOC in water must be broken down and reduced using UV treatment. High purity quartz materials that are partly transparent to short UV wavelengths and specific designs are needed for UV devices intended for TOC reduction. By dissolving molecular bonds and generating aggressive hydroxyl radicals from water molecules that break down organic substances, low molecular weight organics are broken down by an unique 185 nm synthetic UV light and quartz sleeve. In large volume water purification processes, our medium pressure UV systems decrease the amount of conventional lamps by up to 95% while lowering running and maintenance expenses by 50% or more.
