Benefiting From a Lead/Lag Configuration

There are many applications today that offer potential new business for water treatment dealers because of increasingly stringent drinking water requirements. These applications include the removal of arsenic, nitrate, perchlorate, fluoride, radium, uranium and other emerging contaminants. The removal of these contaminants may be required by local, state or federal regulations.

Resin Regeneration Fundamentals

The basic purpose of resin regeneration is to restore the exhausted resin back to its proper ionic form for service. Although there are various manuals and sources that contain information on how to regenerate resins, for many, guessing plays a major role in this process. To eliminate the guess factor from the resin regeneration equation, this article will provide an overview of the basic regeneration procedures and guidelines for softeners and two-bed deionizers.

Resin Sterilization

Ion exchange resin beds are often an attractive growth medium for biological organisms, such as bacteria, mold and algae. In some cases, these growths can build up in the resin bed and physically foul the resin. In most cases, however, the concern is that these organisms will contaminate the effluent water leaving the ion exchange system.

Supercharged POE Systems — Sales Gimmick or Great Benefit?

Using a water softener is a popular and effective method for residential water treatment. A water softener improves water quality by removing hardness and iron, and in most cases, the benefits of the system far outweigh the equipment and maintenance costs.

Chromate

The Boomsnub site in the state of Washington was listed as a Superfund site in 1995. The site consists of two parcels of land, which previously contained two unrelated businesses that contributed separately to contamination of soil and groundwater.

The Boomsnub Metal Plating facility operated on about 0.5 acres, from 1967–1994. This facility was responsible for releases of chromium-contaminated wastes that resulted in contamination of soil and groundwater by hexivalent chrome.

Basic POE System Maintenance

Periodic proactive maintenance of point-of-entry (POE) water conditioning equipment will benefit the end user and the service provider. Consumers generally prefer to be taken care of on a set schedule rather than waiting for a malfunction to occur. For residential applications, an annual visit is typically adequate and can often be combined with other point-of-use drinking water filter service. For commercial customers, more frequent attention is often required, usually with monthly visits.

Uranium Removal by Ion Exchange

Higher pH solutions, through the addition or use of alkalis such as sodium hydroxide, sodium bicarbonate or sodium carbonate, will result in severely decreased uranium regeneration.

Resin Regeneration - More Than Meets the Eye

Frequently there are inconsistencies between the effectiveness of two regenerations even though the same procedure was followed.

Ion exchange resins are regenerated every day, and whether regenerating in huge vessels or regenerating in small laboratory columns, mixed beds or two beds, the object of the regeneration is the same: to restore the exhausted resin back to its proper ionic form for service.
