Process equipment is frequently washed down when switching products. Using the old procedure, the equipment was filled with water, agitated and dropped to waste. Special spray nozzles (designed for cleaning tank cars) were installed to reduce the amount of water needed to clean this equipment.
The use of the spray heads resulted in reducing water use and disposal of 100,000 gallons a year.
