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.
Look at the heating element of a washing machine or dishwasher in a hard water area and you will see a white encrustation containing hardness salts. This commonly is referred to as limescale and is an example of domestic fouling.
Industrial fouling poses a far greater problem than anything in the domestic sector. Huge volumes of fouled fluids are handled, and the systems that contain the fluids can become fouled as well. The quality of water streams used by industry varies widely and gives rise to numerous fouling problems.
Controlling Scale Deposition
A new technology has emerged that can solve scale problems without the need of salts, chemicals or maintenance.

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.
When it comes to keeping their big rigs clean and sparkling, most truck drivers are as particular about a good wash as any car owner might be—maybe even more particular considering the dollars some have wrapped up in their 18-wheelers. Owners of large vehicle fleets such as buses and delivery trucks seem to appreciate the value a clean machine has in properly projecting their corporate image. During winter months in many northern states, just cleaning off road salt and sand is imperative to vehicle maintenance.
Big Rigs Come Clean Using Treated Water
UV is an accepted and rapidly growing technology for treating wastewater in the United States. In Europe, it commonly is used as a primary disinfectant in municipal drinking water systems. Other applications include food and beverage, pharmaceutical, semiconductor and power generation. This article will discuss three other commercially successful and growing applications.
Successful Ultraviolet for Commercial Applications
An environmental consulting firm used bacteria found naturally in soil to treat toxic substances located in contaminated industrial sites.

Extracting the maximum benefit from condensate polishing systems continues to be a top priority among many electric utility plants. With cost reduction pressures and increasing water quality standards, owners and operators continue to evaluate the resin handling procedures that affect corrosion product transport and contaminant ion impurity levels.
