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 (UV) 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 and wherein the input line to the ultraviolet disinfection unit further comprises an obstructive structure disposed therein;
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;
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 unit controller in response to signal provided by the output signal device;
wherein the input line to the ultraviolet disinfection unit further comprises a cylindrical sleeve and the obstructive structure comprises a rod that is disposed transversely within the cylindrical sleeve; and
wherein the obstructive structure disposed within the input line cylindrical sleeve of the ultraviolet disinfection unit further comprises a rod that is disposed transversely within the input line cylindrical sleeve;
the ultraviolet disinfection unit further comprises at least one UV light tube having a quartz sleeve that prevents water from directly contacting the UV light tube; and
the rod imparts to the water entering the ultraviolet disinfection unit a wiping action of the quartz sleeve on a continual basis and improves the efficacy of the UV radiation transmittance inside the ultraviolet disinfection unit.
