Systems and Methods for Controlling the Feed Rate of Chemicals into a Body of Water

A system for controlling a feed rate of at least one chemical into a body of water comprising:

• an assembly for delivering at least one chemical into a reservoir containing the body of water comprising at least one chemical feed pump;
• a water sampling assembly configured to extract water samples from the body of water at different points in time;
• an analyzer in fluid communication with the water sampling assembly;
• a controller in operable communication with the analyzer and the assembly for delivering one or more chemicals;
• and
• a computer-readable storage medium in operable communication with the controller and containing programming instructions that, when executed, cause the controller to:
• a) determine a chemical feed pump usage of at least one chemical being dispensed into the body of water during a designated period of time with the controller, wherein the at least one chemical is dispensed into the body of water with the at least one chemical feed pump and one or more chemical treatment flow tubes that extend between one or more chemical storage tanks and the reservoir;
• and
• b) (i) automatically increase a chemical gain of the at least one chemical in the body water if the pump usage is greater than a first pump usage set-point, or (ii) automatically decrease chemical gain of the at least one chemical in the body water if the pump usage is less than a second pump usage set-point, wherein the chemical gain is increased by increasing the chemical feed rate of the at least one chemical from the chemical feed pumping device into the body of water, and wherein the chemical gain is decreased by decreasing the chemical feed rate of the at least one chemical from the chemical feed pump into the reservoir.
