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.
The new Easy Feeder Starter Kit includes an automatic dispenser and a 64-oz bottle of Pro Res Care resin cleaning solution. The feeder is a non-electric, continuous feed dispenser designed for use with this cleaning solution. When empty, simply replace the old bottle with a new one and insert the wicking cap. The feeder makes it simple to clean and restore resin beds to peak efficiency and maintain water softener performance.
The Pro Easy Feeder is a non-electric continuous-feed dispenser designed for use with Res Care Resin Cleaning Solution. This product is made and assembled in the U.S., and includes a cap, bracket and feeding tube. It allows users to simply clean and restore resin beds to peak efficiency and maintain water softener performance.
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.
