  • Patent number: 11104587
    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.

  • Patent number: 5961845
    Abstract: A dispenser system for treating water containing systems in place with a dry chemical substance. The dispenser has a water soluble pouch housing a dry form of a chemical material to be used in treating the system. The pouch is positioned in a make down unit so that the chemical is dissolved to form a liquid concentrate which is then introduced into a water containing system. A controller is attached to the make down unit to regulate the flow of water into the apparatus and the flow of liquid concentrate out of the apparatus and into the water containing system.
