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.
