Thanks to a new membrane filtration system, National Raisin Company, Fowler, Calif., not only has been able to cut its wastewater costs, but it also has opened up a potentially lucrative source of additional income.
Reverse Osmosis - Anion-Filtration Water Plant Run by a Single Automation Platform with Fieldbus Communications
A new 3.0 mgd water treatment plant on North Carolina's Cape Hatteras is believed to be the first in the United States to apply Foundation fieldbus for device-level control communications. The plant, built by the Dare County Water Department near the famous Cape Hatteras Lighthouse, has been operating without a problem since startup more than two years ago. Fieldbus has been widely applied in all process industries including electric power generation, an industry also cautious to adapt new technology.
WQP spoke with Barry Willson, senior vice president of operations at BEVsystems International, Inc., based in Miami, about the current enhanced water trends that seem to be driving the industry and giving marketers a lot to work with.
I am always shocked to see how few salespeople use a value justification. In my view, this is a critical step in the selling process. Let’s take a look at some of the advantages this technique gives you and then we will look at the actual script for a justification.

Part one of this article appeared in the February issue and described how nanofiltration, reverse osmosis and electrodialysis reversal are being run side-by-side at the Brackish Water Demonstration Facility in California.
The Diablo Canyon Power Plant at Avila Beach in California utilizes seawater for both cooling water and makeup water for steam generation. Ionics, Inc., Watertown, Mass., designed and built and now operates a complete water treatment system serving the high-purity water needs of this power plant. Over the past eight years, the seawater treatment section has demonstrated excellent long-term performance as a result of strong design, consistent maintenance and qualified operators.
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.

In Port Hueneme, California, a state-of-the-art desalination facility uses three brackish water desalination technologies: reverse osmosis (RO), nanofiltration (NF) and electrodialysis reversal (EDR), operated side-by-side to produce over three million gallons per day (mgd) of high quality drinking water. The Brackish Water Reclamation Demonstration Facility (BWRDF) is the cornerstone of the Port Hueneme Water Agency’s (PHWA) Water Quality Improvement Program. In addition to providing desalted water for local use, the BWRDF also serves as a full-scale research and demonstration facility.
Understanding and reacting to the performance of a reverse osmosis (RO) system is necessary for continued successful operation. It is this interaction that allows us to quickly and correctly identify and correct issues that may arise.
