Abstract: Water treatment apparatus including an elongated first water chamber, an inlet for water at one end of the chamber, an outlet for water at the opposite end of the chamber and at least one ultraviolet lamp within and extending longitudinally of the chamber. The chamber may be connected to a second chamber into which air and/or ozone may be introduced through outlets for flow through the second chamber. Alternatively, the first chamber may comprise a chamber which contains the air and/or ozone outlets. A funnel shaped member is provided at the upper end of the first or second chamber to collect bubbles carrying impurities in the water to the surface.
