Abstract: A low cost method and apparatus for maintaining and rejuvenating a septic system in which an activated gaseous fluid formed by irradiating an oxygen containing gas, such as ambient air, with radiation having a wave-length below 200 nanometers produced by a low powered ultra-violet lamp is brought into intimate contact with liquid in the effluent chamber of a septic tank to effect a substantial reduction in the concentration of suspended solids, volatile solids and fecal coliform in the liquid and when the activated fluid is brought into intimate contact with a drainage field of a septic system clogged with water-insoluble sulfides, and polysaccharide gums and anaerobic organisms of the deposits which have clogged the drainage field are removed. The effluent from a septic tank treated with activated fluid after filtering through a sand filter and subjected to a second treatment with the activated fluid produces a discharge of surface quality water.

Abstract: An activated air treatment for water purification utilizes an ultraviolet irradiated activated air stream dispersed into a water tank. Water is continuously circulated through a filter and ion exchange beds and returned to the tank. The ion exchange beds are sequentially regenerated by a closed loop salt water system. The regenerating liquid is treated by a second activated air stream.

Abstract: An activated oxygen product produced by irradiating oxygen with electromagnetic radiation of wavelength less than 200 nanometers, and having an unusually high oxidation potential and unique spectral properties. The product may be used to treat water in order to reduce surface tension, oxidize wastes, reduce manganous ion concentration, and disinfect water without creating carcinogens.

Abstract: Apparatus for producing ozone including a casing through which oxygen is passed, and a supply of radiant energy for converting the oxygen to ozone as the oxygen traverses the casing. One form of radiant energy is ultra violet light produced by lamps within the casing, the lamps comprising fluorite tubes filled with deuterium and/or xenon, and another form of radiant energy is gamma radiation from a radioactive source. The disclosure further includes means for treating water with the ozone in which the water and ozone are directed through a pipe while the dipoles of ozone are aligned by a magnetic field in the pipe.
