Abstract
A system for handling effluent from a film processor. A transportable holding tank is attached to the film processor using quick-disconnect fittings, and accepts effluent discharged from the film processor by gravity. The holding tank is uncoupled from the film processor and coupled to a receiving station with quick-disconnect fittings similar to those on the film processor. The effluent is pumped into the receiving station. The system is designed to minimize exposure to film processing chemicals, and handles parallel segregated streams of silver-bearing and non silver-bearing effluent.
