Diagnosing & Repairing Residential POE Systems: Part II

In the May 2007 issue, we primarily examined how automatic water softeners operate and discussed many of the potential solutions to operational challenges. Observation, documentation and testing were noted as the most important starting points.

In this issue, we will further discuss specific problem areas and how to overcome them systematically.

We will continue where we left off, with brine concentration and contact issues.

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 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.

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.
