Kodak Ektacolor RA Chemistry is used in the processing of color prints RA-4 process, developed in, tray, drum, or rotary tube developing.
If you use Process RA-4 with a separate bleach and fixer, you can regenerate the bleach overflow with this solution.
You can also use this regenerator to prepare a tank solution or bleach replenisher at startup. Regenerating the bleach significantly reduces the BOD, COD, iron, and ammonia in the effluent.
Be especially careful not to contaminate the developer with bleach-fix; even minute amounts of bleach-fix can severely contaminate the developer.
To prevent developer contamination, use a separate mixing container for the developer.
Chemicals are supplied as all-liquid concentrates for easy mixing and handling
