Background
Food Service Application
Food service operations in the commercial sector including restaurants, cafeterias, institutional kitchens and food preparation companies exhibit significant water conservation potential. For example, the dishwashing operation in a typical restaurant consumes over two-thirds of all of the water used by that establishment. In some cases, nearly one-half of the water used in dishwashing is consumed by a pre-rinse spray valve (PRSV) used to remove food from dishware, utensils, and pans prior to placing them in the dishwasher.
