Metals Plant Needs High-Purity Water   Water Quality Products July 2003   Crown Solutions, Inc.
Dayton Progress Corp.'s focus has been on manufacturing metal punches, punch blanks and metal stamping tools. It also would take experienced water treatment professionals to ensure that the proper quality water was used in each process. That is why it relied on Crown Solutions, Inc. to manage the point-of-use (POU) and point-of-entry (POE) water treatment for each of its manufacturing processes that required water.

Brominated Resins   Water Quality Products July 2003   Ken Korslin, CWS-III, Pentair Water Treatment, Plymouth Products Division
In 1957 The Dow Chemical Corp. addressed the negatives of using bromine by creating a brominated ion exchange resin, which opened up the use of bromine in offshore water treatment applications.2 Today, polybromide resin is used in many offshore water treatment systems. The fact that bromine can be added to water that previously has been chlorinated makes polybromide resin a practical solution to accommodate the multiple sources of water in offshore applications.

Arsenic Treatment Options for the Southwest   Water Quality Products February 2003   Arizona Water Quality Association
While high concentrations of arsenic are found mostly in the Western region of the United States, parts of the Midwest and New England show levels of arsenic that exceed the newly approved U.S. Environmental Protection Agency (EPA) standard of 10 parts per billion (ppb). Individuals not willing to wait for their water system's compliance with the arsenic standard currently are looking for treatment systems to use in their homes. POU and even point-of-entry (POE) treatment systems are an attractive solution for these individuals. The process should begin with a basic understanding of arsenic contamination and the element's chemistry, a complete water quality analysis of the application-specific water and the knowledge of available technologies.

The New West   Water Quality Products February 2003   Wendi Hope King
The "New West" has emerged full of concerns and new laws that make water treatment necessary and some that make it harder to sell. California is well-known for its progressive way of thinking. Although often its tactics may be questioned, many people anxiously wait to see what will be next. Will there be more bans? Stricter regulations? The state's legislation continually has been challenged by the Water Quality Association, NSF International, water treatment professionals nationwide and other organizations. With all of this in mind, let's take a look at some things that are happening in the Western region.

Arsenic Overview Series - Part 2   WaterInfoCenter January-December 2003   Sherry Odom
Consumers unwilling to drink arsenic contaminated water are demanding a more rapid implementation. Publicly owned utilities, however, will be held hostage from implementing a more rapid solution due to government approval cycles, annual budgets, required biding processes and slow implementation schedules. As a result, in-home treatment systems, which immediately can be installed, are a very popular treatment option for individual homeowners. Other advantages such as low implementation/operating costs and improved flexibility make the POU/POE approach option appealing.

POU Technology Demonstrates Effectiveness   Water Quality Products March 2002   By Jennifer Mathis, Apyron Technologies, Inc.
In March 2001, the U.S. Environmental Protection Agency (EPA) withdrew a proposal for a lower maximum contaminant level (MCL) for arsenic in drinking water that would bring the standard from 50 parts per billion (ppb) to 10 ppb. At that time, the EPA commissioned three studies to examine the benefits, costs and health effects associated with a lower standard for arsenic.
