ADVANCEES - Ultrapure Water Application - Custom skid-mounted water purification equipments - Water and Wastewater
Ultrapure water (UPW) is water that has been purified to very strict specifications, containing by definition only H20, and H+ and OH- ions in equilibrium. Therefore, ultrapure water conductivity is about 0,055 uS/cm at 25oC, also expressed as resistivity of 18,2 MOhm. Ultra-pure water is mainly used in the semiconductor and pharmaceutical industry often is produced through processes like membrane filtration or ion exchange to reach the ultimate conductivity of 10 uS/cm. The demineralized water is then processed through a high performance Mixed Bed or by Electro deionization.
