Ultrapure water Purification system 

Ultrapure water (UPW), high-purity water, or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a commonly used term in the semiconductor industry to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including organic and inorganic compounds; dissolved and particulate matter; volatile and non-volatile, reactive and inert; hydrophilic and hydrophobic; and dissolved gases.
Ultrapure water is treated through multiple steps to meet the quality standards for different users. The primary end-users of UPW include these industries: semiconductors, solar photovoltaics, pharmaceuticals, power generation (sub and supercritical boilers), and specialty applications such as research laboratories.
Our Ultrapure Water Machines yield from 5L/Hour to 60L/Hour., and the ultrapure water system has a quantitative and quality module for water usage.  Email us for more details: sales@yk-instrument.com
