Part 2 of Water Control’s Animated Series on RO Is Now Available

A complete high-purity (or ultra-pure) system utilizing reverse osmosis/deionization (RO/DI) requires more than just a set of filter membranes and a pump. Every application is different, although all require certain equipment for pretreatment, post-treatment, and re-pressurization/delivery. In this short animated video, Water Control breaks down the complete high-purity production process into bite-size, easy-to-understand segments. Topics covered include:

  • Pretreatment of the raw water for temperature, hardness, chlorine, and more
  • RO membrane filtration
  • DI “polishing” of the water
  • Re-pressurization/delivery equipment
  • Continuous loop disinfection
