Abstract:
1. A water treatment apparatus for use in the treatment of an open or closed body of water including water in a vessel, pipe, reservoir, river, chamber, lake or similar bodies of water, the water being retained in a water containment means being referenced or tied to ground potential, the apparatus including an energisable material defined as an active electrode being configured and arranged for placement in the body of water, the active electrode being adapted to be energised or electrostatically charged with a negative electrostatic voltage charge from a power supply means, in use, to induce and set up an electrostatic field in the water causing contaminants in the water effected by the induced charge to bond to solid surfaces in the water and to permit removal from the water, and wherein the energisable material is adapted to form part of a base platform configured and arranged for placement in the flow of wastewater, the platform having a substantial surface area and a plurality of spaced apart apertures therein, in use, for allowing water to flow therethrough, and wherein the side of the platform away from the incoming flow of water is covered with a media layer suitable for use in hosting bacterial cultures, and further including an electrified conductive mesh layer adjacent the media layer opposite the side in contact with the base platform, the mesh layer, in use, being supplied with an electrostatic negative voltage charge of between −0001 and −24 volts direct current to attract suspended solids in the wastewater and bond aerobic and/or anaerobic bacterial cultures to the media layer.
