High Purity Water

Water that is free from any impurities or contaminants like particulate matter, organics or dissolved minerals, is a vital part of countless products and processes. The first step in the production of high purity water is generally referred to as pretreatment, usually consisting of filtration and/or softening. To produce ultra pure water, however, it is necessary to remove the dissolved minerals as well. To accomplish this, two processes are used: reverse osmosis (R.O.) and deionization (D.I.)

Reverse Osmosis -- uses a semi-permeable membrane.
Deionization -- involves an ion exchange process.

Reverse Osmosis Applications

• Typical applications where reverse osmosis units are used include:
• Pharmaceutical
• Still pretreatment, USP purified, and process waters.
• Electronics
• Pris
• Improves operating efficiency and extends orifice life.

Deionization Applications

Typical applications where deionizers are used include:

• Manufacturing
• For pron
• Reduces scaling and dusting.
• Printing
• Reduces chemical costs in mixing water soluble ink.
• Horticulture
• Reduces leaf spotting and mineral build-up in planting soils.
