Method and system for controlling water system fouling
First Claim
1. A water treatment system comprising:
- an ion generator for applying metallic ions to the water having an inlet line and an output line;
an output signal device for providing a signal based upon a flow rate of water passing through the output signal device, the output signal device having an input line and an output line, wherein the input line of the output signal device is connected to the output line of the ion generator;
an ultraviolet disinfection unit for applying ultraviolet radiation to the water having an input line and an output line, wherein the input line of the ultraviolet disinfection unit is connected to the output line of the output signal device;
an ion generator controller electronically coupled to the ion generator for controlling the ion generator;
an ultraviolet disinfection unit controller electronically coupled to the ultraviolet disinfection unit; and
a programmable logic controller electronically coupled to the output signal device and the ion generator controller and the ultraviolet light disinfection unit controller, whereby the programmable logic controller controls the ion generator controller and the ultraviolet disinfection controller in response to signal provided by the output signal device.

Abstract
A method and system flows water through a water system in proximity to an ion generation device and to a source of ultraviolet (UV) radiation that combines photochemistry principles, heavy metal toxicity, and UV light radiation to form a highly effective combined water disinfection process. Using ion generation and UV irradiation, the method and system synergistically improves the disinfection and bactericidal effects of ion generation or UV radiation working individually by making ion-exposed microorganisms more susceptible and less resistant to the bactericidal effects of UV radiation. The combined method and system of the present invention may include control means such that the method and system can be configured for single pass through, dual pass through or for recirculation such that the order of exposure to the ion generation and UV radiation aspects can be varied or altered. The method and system of the present invention may also be provided with means for controlling the system flow rate, ion generation and UV radiation levels to maximize performance, to minimize energy consumption, and, in some situations, to selectively target certain microorganisms for inactivation.
