Abstract
An apparatus for transferring effluent from photograph development systems, especially highly automated, high-volume developer systems. A silver-recovery system discharges an iron-rich solution into a tank. Developer fluid and fixer solution is mixed with the iron-rich solution in the tank to buffer its pH. A float in the tank activates a switch located outside the tank to actuate a pump for evacuating the mixed effluent from the tank for disposal. Water may be mixed under pressure with the pumped effluent to reduce clogging in effluent drainage lines due to precipitate and other and build-ups from effluent.
