ABSTRACT:
An effluent precipitation and neutralization chamber is useful for treating x-ray photographic chemicals prior to discharging them into a drain. Desilvered photographic fixer is mixed with spent developer within the chamber. The resulting iron precipitates settle to the bottom of the chamber or adhere to ribbon-like flow restrictors within the chamber. Relatively clear fluid of approximately neutral pH concentration is discharged to the drain. The chamber is openable for removing and properly disposing of the iron precipitates.
