Ultrapure Water Production

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. Ultrapure water production often has to be done in 2 steps. For example, from tap water or fresh groundwater, the water should first be demineralized by 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. Ultra-pure water is mainly used in the semiconductor and pharmaceutical industry. Because of the continuing miniaturilisation in the semiconductor industry, the specifications become stricter every year. Ultrapure water is also utilized in the production of flat panel displays and photovoltaic panels, and in the pharmaceutical industry, it is critical for injection and for cleaning process equipment. The power industry is yet another user, employing ultrapure water to serve as feed water for steam boilers. The pressure membrane technologies of microfiltration, ultrafiltration, Nano filtration and reverse osmosis are the most versatile and, hence, most widely used as the lynchpin of most ultrapure water production systems. In particular, membrane technologies possess certain properties that make them unique when compared to other water treatment technologies. These include:

■ Continuous process, resulting in automatic and uninterrupted operation

■ Low energy utilization involving neither phase nor temperature changes

■ Modular design-no significant size limitations

■ Minimal moving parts with low maintenance requirements

■ No effect on form or chemistry of contaminants

  • Membrane filtration
  • Electrodionisation
  • Microfiltration
  • Membrane elements
  • Applications in Pharmaceutical and Biotechnology Companies
