ABSTRACT:
An apparatus for treating a waste solution generated when a photosensitive material is processed by an automatic developing machine includes a waste solution reservoir which is maintained at a constant level. A drum, partially immersed in the waste solution, is rotated to coat its surface. The drum is heated to produce a waste vapor. The waste vapor is condensed by a condenser and filtered and solid wastes are scraped from the surface of the drum. The condenser has a drain tank for collecting condensate and a non-condensable gas component. The interior of the drain tank is sealed to form an air tight seal and has a vent for exhausting the non-condensable gas component from the interior portion to the outside. The air vent includes an absorption tower to treat the non-condensable gas component.
