Naturally occurring impurities are present in all raw water supplies, and will be introduced in the process operation or end product when untreated water is used. Typical impurities are calcium, magnesium, sodium, alkalinity, chlorides, sulfates, nitrates, and silica. All of these contaminants cause scaling in boilers, spotting on finished surfaces, precipitation in chemical products, defects in electronic components as well as other problems in each process application. The EBD Water IED Ion Exchange Systems will reduce these contaminants to negligible levels.

An EBD Water IED Demineralizer is a complete system utilized to deionize water or other liquids to an acceptable level for various industrial uses.

The EBD Water Demineralizers can be used as primary or polishing Ion Exchangers. When used as a primary ion-exchanger following an EBD Water Reverse Osmosis System, water of 10 - 18 megohm is produced. As a polisher, an EBD Water Demineralizer can produce water of up to 18.3 megohm quality.

EBD Water Demineralizers consist of single or multiple two bed or mixed bed units, depending upon production requirements and the degree of purity needed for a particular process. Because of the characteristics of the raw water supply, many systems require cation and anion exchangers of unequal sizes to obtain optimum performance. The addition of a decarbonator for the removal of CO₂ will reduce the load on the anion exchanger.

Weak base resins are used to produce low solids water, however silica and CO₂ are not removed by these units and require the use of strong base.
