AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
This patent-pending POU water filtration device produces drinking water without frequent maintenance, chemical additions or component replacement. The system traps and neutralizes contaminants through an ion exchange process. It processes enough water to support a family of six, includes built-in safe water storage and lasts for 10 years. The system meets the World Health Organization’s Household Water Treatment specifications for removing bacteria, protozoa and viruses.
In my first article, “Traditional Treatment Methods” (June 2014), I touched on traditional methods of residential water treatment and conditioning such as water softeners, reverse osmosis and ultraviolet systems.

One of the most pronounced shifts in the water treatment industry is the rapidly burgeoning need to improve water quality. The need for water treatment systems is growing quickly, and, unfortunately, North America is hardly immune to challenges.

It all began for me in the fall of 2012, when D.J. Shannahan, owner of Sharp Water and a Water Quality Assn. (WQA) board member, provided me with his wealth of experience to assist the state of Delaware in revising a restrictive septic law. During a visit in February 2013, Richard Mest, WQA president and president of Master Water Conditioning Corp., immediately offered his years of legislative experience throughout the U.S. and specifically in Washington, D.C., to help in Delaware.

The Water Quality Assn.’s (WQA) Gold Seal product certification program continues to grow and expand to meet the needs of the industry. This is being accomplished while maintaining quality control procedures and customer service. Regulatory acceptance of Gold Seal certification has reached a new high with the addition of the U.S. Environmental Protection Agency’s (EPA) Energy Star program, which is now accepting the Gold Seal program for compliance of water coolers.

It has been almost three years since California passed Assembly Bill 1366, allowing municipalities to ban the sale and use of water softeners. Water Quality Products Assistant Editor Nicole Bowling spoke with Mike Mecca, past president of the Pacific Water Quality Assn. (PWQA), about how the bans are affecting the local water quality industry.
Nicole Bowling: What is the status of the water softener ban legislation in California?
Water softener resin is extremely porous, which is beneficial because it allows for more surface area to capture calcium and other metals in source water. Surprisingly, 99% of ion exchange actually happens in the interior of the bead. Resin beads, ranging in size from 16 to 50 mesh, are abused daily during the backwash process and by contaminants in the source water. Resin could last much longer in these hostile environments with a few fairly inexpensive solutions.
Cleaning options to reduce resin fouling
Ion exchange resins used in softening, anion or deionization applications are designed to remove certain ionized substances from water. The resin beads typically range in size from 16 to 50 mesh (1.2 to 0.3 mm) and although they are designed for the removal of dissolved ions, they can become a very effective filter media.
In some specialty applications (e.g., condensate polishing) resins are used as much for their filtration properties as for their ion exchange characteristics. For the most part, however, it is a good idea to keep the resin bed free of suspended particles.
