Abstract: An apparatus for treating waste water in which a series of filtering pads are formed by a plurality of offset nets made from ribbon-like lines having a multitude of ringlets. The nets are mounted in planar configuration within a frame at spaced intervals, with the plane of the nets being supported at an angle of 40.degree. to 50.degree. from the horizontal. The frames may be placed in any water system such as fabricated basins, ponds, ditches, rivers or lakes. Also, one or more of the netted frames may be placed in a basin for anaerobic treating organic waste water. Water circulation means are fixed within the tank for repetitive flow through the filtering pads and the delivery of oxygen and/or other process elements.

Abstract: A method and a portable apparatus is provided which can be transported to the area of treatment, generate silver ions or ions of other selected elements such as copper, uniformly distribute the ions over both confined and extended areas of water and land, and destroy infectious bacteria and/or other undesirable microorganisms in such areas. Water under pressure is passed through a manifold containing silver electrodes (or other desired metal electrodes) which are energized to produce ions. The solution with the high potency disinfecting ions is delivered to a sprinkler or other form of spraying device. The system is portable so that the apparatus can be moved to multiple locations or maneuvered within a given treatment location.
