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.
