Chemical delivery system with dilution control

A method of delivering a mixed solution from a chemical delivery system configured with dilution control, comprising:

• receiving, by a control unit comprising a processor, measured flow rates from a plurality of flow rate sensors of the chemical delivery system, each of the plurality of flow rate sensors coupled to a corresponding concentrated chemical line and configured to measure a flow rate of a concentrated chemical therethrough, each concentrated chemical line being fluidly coupled to a concentrated chemical inlet of an eductor of a plurality of eductors, wherein each of the plurality of eductors are fluidly coupled to an inlet port of a chemical delivery manifold via a motive fluid inlet thereof, said motive fluid inlet fluidly coupled to a valve of a plurality of valves, and wherein each of the plurality of eductors comprises a mixed solution outlet;
• transmitting, by the control unit, instructions to cause at least one metering device of a plurality of metering devices to adjust a rate of dispensing of the concentrated chemical through the corresponding concentrated chemical line for at least one of the concentrated chemicals based on the measured flow rates, wherein each of the plurality of metering devices is coupled to the corresponding concentrated chemical lines and configured to control a rate of dispensing of the concentrated chemical passing therethrough;
• and
• transmitting, by the control unit, a control signal to cause each valve of the plurality of valves to be operated, such that each valve is operated independently to selectively control flow of a motive fluid through a respective motive fluid inlet of an eductor of the plurality of eductors such that each eductor is configured to individually mix the concentrated chemical into the motive fluid to form a mixed solution having a controlled flow rate of the concentrated chemical to thereby individually control a dilution of each concentrated chemical in the motive fluid.
