NOVELTY - Solar energy water treatment apparatus for minimizing bacteria and other pathogens in treatment water supplied to the apparatus, the apparatus comprises a metal surface receiving the treatment water via supply means at one end region for flow along the metal surface in a thin surface flow, a clear or translucent solar energy transfer panel, water collection means for collecting the treatment water at an opposed end region of the metal surface after passage there along.    USE - The solar energy water treatment apparatus is useful for minimizing bacteria and other pathogens in treatment water supplied to the apparatus (claimed).    ADVANTAGE - The apparatus is highly efficient and effective in minimizing parasites, bacteria and other pathogens in the water.    DETAILED DESCRIPTION - Solar energy water treatment apparatus for minimizing bacteria and other pathogens in treatment water supplied to the apparatus, the apparatus comprises a metal surface receiving the treatment water via supply means at one end region for flow along the metal surface in a thin surface flow, a clear or translucent solar energy transfer panel spaced above and adjacent to the metal surface spanning the area of the metal surface on which the treatment water flows, water collection means for collecting the treatment water at an opposed end region of the metal surface after passage there along, the treatment water flowing at a flow rate of at least 0.1 l/m2/minute of the metal surface. An INDEPENDENT CLAIM is solar energy treatment installation comprising at least first and second the solar energy water treatment apparatus, treatment water collected from the first solar energy treatment apparatus being delivered to the one end region of the metal surface of the second solar energy treatment apparatus.
