Abstract: A system and method of controlling the treatment of water systems comprises multiple feeders for separately feeding treatment products, in the form of concentrated, non-hazardous, liquids with a single active ingredient, to a water system to treat various issues, such as corrosion and biofilms. A sensor verifies delivery of the treatment product to the water system. A controller controls activation of each feeder to control a feed rate according to programmed functions. The controller receives signals from sensors, which can be used as inputs in calculating feed rates or feeder activation times according to the programed functions and can alter treatment product feed rates based on real time data regarding water system chemistry or flow rates. The controller can send and receive data, signals, alerts, alarms or changes in programming to or from remote users, remote computers, or a water system controller.
