Abstract
The invention involves a mixing apparatus capable of mixing two or more chemicals using a motive liquid. An ejector draws in a first chemical which is directed to the input of an eductor. A second chemical is connected directly to the eductor. The motive liquid provides the motive force for both the ejector and the eductor. By reason of the feeding of the first chemical to the eductor from the separate ejector rather than directly into the eductor, the ratio of the first chemical to the second chemical fed into the eductor is more accurately controlled than if both chemicals were directly fed to the eductor. The chemicals are mixed in the eductor and are discharged as a foam preferably through a foam nozzle.
