A method for processing fluid contaminants containing organic and inorganic pollutants and foulants or other contaminants in an aqueous feedstream, comprising the steps of directing the feedstream to a processing area for oxidation of the fluid contaminants; homogeneously dissolving and solutionizing an ozone gas volume into the feedstream, such that the feedstream becomes a substantially single phase fluid; measuring ozone activity in the feedstream after leaving the processing area; selectively and optionally making adjustments to the feedstream based on the results of the measuring step; conveying the single phase fluid through a filter media installation and generating an effluent portion volume; and advancing and measuring ozone activity of the effluent portion volume, and the volume and amount of the effluent portion volume.
75. A method for cleaning a filter installation, where the filter is in an installed position on line and used for environmental filtering of a wastestream, and respective volumes thereof from respective source areas of the wastestream, having fluid contaminants generated by at least one of respective manufacturing and nuclear work facilities, and comprising a system of conveyance, under continuing, monitored pressure, for forward and frontal entry and passage through the filter installation to be cleaned of a homogeneous cleaning fluid or portions thereof; said method further comprising the steps of directing the wastestream, and the respective volume thereof, from the respective source area of the wastestream to a processing area for oxidation of the fluid contaminants; homogeneously dissolving and solutionizing an ozone gas volume into the wastestream under pressure, such that the wastestream becomes the homogeneous cleaning fluid, said cleaning fluid being a substantially single phase fluid; verifiably measuring the ozone activity in the cleaning fluid after leaving the processing area, proximate to at least one point of respective points extending to and beyond the filter to be cleaned; and selectively making adjustments to the pressure exerted in the processing area and the ozone gas volume supplied to the processing area during an on-going cycle, and recycling and adjusting wastestream volumes and any volumes of the cleaning fluid not passing through the filter to be cleaned back to the processing area, thereby reducing ozone bubbles and white water therefrom in the wastestream and cleaning fluid as it is directed in the system of conveyance from within the processing area to the filter installation to be cleaned;
wherein said method further comprises generating an effluent portion volume after the forward entry and passage through the filter installation to be cleaned of the homogeneous cleaning fluid, said effluent portion volume being equal to from about 25 percent to about 30 percent of the respective volume of the waste stream from the respective source area of the wastestream.
76. The method of claim 23 , wherein the pressure gradient is brought about by an ozone generator at an output of at least from about 1 p.s.i.g. to about 150 p.s.i.g.Cited by (0)
