Cochrane Ultra Pure Water
Cochrane by Newterra offers two paths to Ultra Pure water in conjuction with our Delta Reverse Osmosis product series: Ion Exchange and Electro Deionization (EDI)
Ultrapure water 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. 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. This page is focused on EDI.
