Abstract
A chemical delivery system that delivers concentrated liquid chemical using a non-liquid motive fluid to deliver the concentrated liquid chemical in an undiluted form to a point of use. The concentrated chemical is delivered by the motive fluid by way of the aggressive interaction of a high-pressure jet stream of motive fluid causing a nearly complete local vacuum such that the concentrated chemical is drawn under low pressure into a jet vortex to form a chemical dispersion. Forming the chemical dispersion by way of this venturi eduction process occurs in a substantially continuous real-time manner allowing for multiple methods of controlling the total amount of chemical delivered and the rate in which it is delivered to the application device.
