Abstract: An apparatus for pollution control in treating the effluent employs an evaporation stage where the effluent solutions are heated to 150.degree. Fahrenheit. The resulting steam and vapors are then oxidized by photoysis and photolytic catayzed ozone before the steam and vapors are discharged through a rubber coated dryer duct. The apparatus is comprised of two main units, a lower evaporation sump unit and an upper photolysis and blower unit. The sump is manually filled through a port located in the top of the blower unit. The operator will then switch the main power switch to "ON" and activate the system. This includes activation of an ultraviolet lamp, blower and heat belts. The heat belts are fixed around the base of the sump.

Abstract: A combination of pollution control technologies are employed in the treatment of effluent from photographic processing. The technologies employed are evaporation, oxidation by photolysis and catalyzed ozone, condensation, treatment by activated carbon and electrolysis. The method includes the steps of filtering the liquid wastes, electrolytically treating the filtered liquid, evaporating the wastes to create steam and vapors, oxidizing the steam and vapors by photolysis and photolytic catalyzed ozone, and condensing the vapors and passing them through a column of activated carbon. The carbon is regenerated by oxidizing the carbon sites with ozone.

Abstract: The apparatus uses a combination of technologies for treatment of hazardous and nonhazardous liquid wastes. The first treatment step is an evaporation stage where the liquid wastes are heated. The resulting steam and vapors are then oxidized by photolysis and photolytic catalyzed ozone before they are condensed. The steam and vapors are then condensed and the condensate is passed through a column of activated carbon. The activated carbon absorbs any unoxidized Chemical Oxygen Demanding (COD) species and aids in the control of any odors which may be emitted in the evaporation stage.

Abstract: Metals are removed from waste water by chemical precipitation and filtration. The system is controlled by a control system responsive to an ion specific electrode and a pH responsive electrode in a manifold that recycles filtrate to a reaction tank where precipitation occurs.
