<p>An improved chemical dispenser includes a plurality of eductors for drawing chemical into a diluent to produce an effluent, each eductor of the plurality selectively discharging via a baffle tube into a single common discharge tube. The effluent flow parameters are insufficient to cause effluent from a selected eductor to flow into a chemical source coupled to a non-selected eductor, and are insufficient to draw chemical from a non-selected eductor into the effluent from a selected eductor.</p> |
