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.

Grease is clogging sewers nationwide, creating a costly mess to clean up and a dilemma for officials and regulators. Recently, the Wall Street Journal reported that 75 percent of the sewer systems in the United States work at only half capacity because of grease clogs. The cost of keeping sewers open, a cost borne by taxpayers at a local level, is $25 billion per year. The increase in grease in sewer lines is a direct result of the phenomenal growth in dual-income households who choose to eat out or take-out rather than cook at home.
