Arsenic Removal by Regenerable Anion Resin

In January 2006, the U.S. Environmental Protection Agency started enforcing the new arsenic limit of 10 parts per billion (ppb) in drinking water. The previous limit was 50 ppb. Since that date, there has been a flurry of activity in bringing selective arsenic media to the market.

Positives & Negatives

All raw water supplies contain dissolved ions that are positively or negatively charged. The positively charged ions (called cations) include calcium and magnesium, which constitute hardness. Other cations present in water are sodium, potassium and iron. The negatively charged ions in water (called anions) include sulfates, chlorides, bicarbonates and silica.

Diagnosing & Repairing Residential POE Systems

Residential softeners and filters may work wonders when conditioning water, but they will eventually need service. Diagnosing and repairing residential point-of-entry water conditioning systems need not be a profitless, multiple trip ordeal that results in an exasperated service technician and a befuddled customer.

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.
