Reverse Osmosis Filter Monitoring

The Semiconductor industry uses ultrapure water to rinse away contaminants from the silicon wafers after each layer of the fabrication process. To ensure effective rinsing after each step could require thousands of gallons of water. If the water has even the slightest impurities, the semiconductors can potentially be contaminated, leading to scrap waste and loss of weeks of production.

Many industries use reverse osmosis (RO) technology in the water purification process. The importance of pure water can include public safety, product quality, and reliability of production equipment. An RO system functions by creating a differential pressure across an array of filters. Pressure is applied to the feed water side of the system to force water through a semi-permeable membrane. The membrane blocks contaminants to allow permeate water to pass through.
