Model RO2002 Standard System

A single RO system can be used to pretreat the tap water feed for several Type I or Type II DI lab water purification systems, and/or point-of-use locations.

This system is also available for a high flow, high capacity applications: Model RO2000-03.

A Reverse Osmosis System should be considered under the following circumstances:

• Incoming tap water contains more than 170 parts per million (ppm) of total dissolved solids.
• DI water usage exceeds 40 liters per day on a Type II DI System.
• DI water usage exceeds 20 liters per day on a Type I DI System.

There are two criteria to consider when determining if a reverse osmosis pretreatment system is either required, or can be justified, based on cost savings:

• Can the DI system alone produce the desired quality and quantity of purified water that is needed for the applications at hand? IF NOT, AN RO PRETREATMENT SYSTEM IS REQUIRED.
• Would it cost more overall (including capital and operating costs over 1-3 years), to process the tap water via DI alone, or with a combination of RO plus DI? IF DI ALONE COSTS MORE, AN RO SYSTEM IS JUSTIFIED.
