ABSTRACT:
A low-voltage ballast-free energy-efficient ultra-violet material treatment and purification system and method having an ultraviolet (UV) source comprising a gas discharge UV lamp having spaced electrodes, a source of a low-voltage, high-frequency alternating current square wave voltage and connected directly to the spaced electrodes to non-thermionically excite the gas discharge UV lamp. A flow sensor is used to proportionately control the intensity of UV generation as a function of flow rate.
