  • Reverse Osmosis: How Does It Figure Into a Dialysis Water System?

    Better than 95% of all dialysis centers use water purification equipment to purify water for dialysis. The centerpiece of these water purification systems has become reverse osmosis. In conjunction with sound pretreatment, RO has proven itself to be the safest, most reliable, and most economical method of purifying water for dialysis. Water plays an important, life-sustaining role for dialysis ...

  • Does Your Facility Need a Reverse Osmosis or Nanofiltration System?

    Reverse osmosis (RO) and Nanofiltration (NF) are used across a wide variety of industrial applications for removal of dissolved materials from liquid streams. Implemented judiciously, RO and NF are effective strategies for recycling process liquids, reducing waste water, recovering and concentrating dissolved materials, and generating potable water. If your industrial facility requires removal of ...
