Industrial Fouling

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.

Softeners Treat Truck Wash Water

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.
