Lenntech Water Treatment

Ultra pure water treatment

Ultra pure water is mainly used in the semi conductor and pharmaceutical industry. Because of the continuing miniaturilisation in the semi conductor industry, the specifications become more strict every year. Ultra-pure water contains by definition only H20, and H+ and OH- ions in equilibrium. Therefore, ultrapure water conductivity is about 0,054 uS/cm at 25oC, also expressed as resistivity of 18,3 MOhm.

Ultra pure water is mainly used in the semiconductor and pharmaceutical industry.

Ultrapure water production often is produced through processes like

 membrane filtration or ion exchange to reach the ultimate conductivity of 10 uS/cm.

The demineralised water is then processed through a high performance Mixed Bed or by Electrodeionization.
