Waste solution treating apparatus

A waste solution treating apparatus for use with a photographic processing apparatus which is adapted to process a photographic material with a processing solution and to dry the processed photographic material in a drying chamber, a predetermined amount of said processing solution under working being run to be waste and to supply replenishing solution continuously, said apparatus comprising;

• a housing having a partition wall which is partly defining said drying chamber;
• means for discharging said processing solution to be wasted into said housing;
• treating means disposed in said housing for allowing said processing solution discharged into said housing to flow thereover;
• means for conducting air heated in said drying chamber of said processing apparatus into said housing in order to heat said treating means, thereby at least condensing said processing solution while said processing solution is flowing over said treating means.
