ABSTRACT:
A portable self-contained solar powered water purifier for swimming pools, spas, and other bodies of water is disclosed. The purifier includes a buoyant housing for supporting a solar cell array above the surface of water to be treated and a purification cell below the surface of water to be treated. Suitable electrical connections, between the solar cell array and purification cell, are sealed to prevent the entry of water therebetween which could result in electrical shorts and corrosion. The purification cell includes a sacrificial anode, having a metal alloy essentially composed of copper and silver and a cathode which is preferably constructed of stainless steel so as to not react adversely with the sacrificial anode. Metallic copper and silver ions are released by the sacrificial anode to prevent algae and bacterial growth. The anode and cathode are structurally interrelated and secured to each other and to the buoyant housing and the solar cell array to provide a practical, durable and long lasting unit.
