Water: Photo Processing

Effluent Guidelines: Photographic Processing

photoprocessing

The photoprocessing industry includes establishments that are engaged in providing the following services: portrait photography for the general public; commercial photography; commercial art or graphic design; or photo finishing.

In 1976, EPA promulgated a final rule establishing BPT for the Photographic Category (40 CFR 459). BPT regulations under Part 459 limit direct discharges of wastewater for silver, cyanide, and pH. In 1997, EPA published Preliminary Data Study for the Photoprocessing Industry (1997 PDS) (U.S. EPA, 1997). That study noted that most photoprocessing facilities are small (less than 10 employees), typically discharging less than 1,000 gallons/day of wastewater, and overwhelmingly discharging to POTWs.

What is Photographic Processing?

Photographic processing is the development or printing of paper prints, slides, negatives, enlargements, movie film, and other sensitized materials. The Photographic effluent guidelines regulate direct dischargers that process more than 150 square meters (1600 square feet) per day. Both commercial and military facilities are potentially subject to these regulations. The process water used in photoprocessing typically includes 1) film and paper wash water, 2) solution make-up water and 3) area and equipment wash water. The typical constituents of the photoprocessing wastewater streams are listed below.

  • Organic Chemicals
  • Chromium Compounds
  • Ferricyanide
  • Silver
  • Thiocyanate
  • Ammonium Compounds
  • Sulfur Compounds
  • Phospate
