| titleOfInvention |
Electrolytic process for treatment of photographic wastewater effluent |
| abstract |
There is disclosed a system for treatment of wastewater effluent from a photographic process which produces a developer effluent, a bleach effluent and a fixer effluent. The system comprises a developer treatment zone, a bleach treatment zone and a fixer treatment zone. Within each zone, there are provided defined means of pH adjustment of the effluent and a defined electrolytic cell of electrolysis of the effluent. A process for conducting the system is also provided. The invention may be advantageously used to reduce the concentration of or eliminated chemicals contained in the effluent. |
