Water purification system

Water purification system

Millipore Corp.`s new Milli-RX water purification systems for the laboratory consistently produce ultrapure water from tap water using a combination of reverse osmosis (RO) and its proprietary ELIX deionization technology. Milli-RX product water meets or exceeds CAP, ASTM and NCCLS Type II specifications. Within the ELIX deionization module, mixed-bed ion-exchange resins are continually regenerated in place by an electric current. Because the resins are never chemically regenerated or stored outside the system, there is no risk of resin contamination by bacteria, colloids, or particles. Prior to the deionization step, water is pretreated by reverse osmosis, which removes a high percentage of the four main contaminants found in tap water: inorganic ions, dissolved organics, particles and microorganisms. Product water from Milli-RX systems has 10-15 megohm-cm resistivity and a total organic carbon (TOC) level of less than 50 ppb. Systems are also available which produce 20, 45 and 75 liters per hour of ultrapure water.
