Patent ID: 7754082

Claim:
A method for treating a liquid with a treatment additive, the method comprising the steps of: providing a system comprising a reactor having a first inlet for receipt of an amount of the liquid, a second inlet, for receipt of the treatment additive, and an outlet for flow of an amount of treated liquid from the reactor, and a controller operably connected to the reactor at the first inlet, the second inlet, and the outlet, the controller capable of controlling and monitoring the amount of liquid entering the reactor through the first inlet, the amount of treatment additive entering the reactor through tile second inlet, and the amount of treated liquid exiting the reactor through the outlet, and the controller further operable to measure the amount of treatment additive present in the treated liquid exiting from the reactor; establishing in the controller the desired ranges for at least one parameter related to the operation of the system; entering into the controller the volume of liquid to be held in the reactor; calculating with the controller a hydraulic retention time; calculating with the controller a treatment additive uptake rate; calculating with the controller a treatment additive demand; and powering on the flow of liquid and treatment additive based on the calculated values.
