Abstract:
1. A bathing system for projecting a mixture of water and at least one injectant onto an object for washing the object, the system comprising: (a) a first injectant dispenser configured to store an injectant; (b) at least one water sprayer having an inlet and outlet; (c) at least one differential pressure injector having a primary inlet in fluid communication to a water source, an outlet in fluid communication to the inlet of the at least one water sprayer, and an injectant inlet in fluid communication with the first injectant dispenser, whereby the injectant can be introduced into water flowing through the differential pressure injector; and (d) a fluid path bypassing the at least one differential pressure injector and a valve in the bypassing path for regulating passage of fluid through the bypassing path, the at least one water sprayer and the at least one differential pressure injector being configured to maintain a water-to-injectant ratio to within a range of about a 50% variation of a midpoint of a mixing ratio range associated with the injectant when water flow rate is no higher than about 4.0 gallons per minute and varies over a range of 20% of a midpoint of a range associated with the water flow rate.
