Summary
A new X-ray film processing system significantly cuts water use by 88% and eliminates silver pollution. Solid photo chemicals also reduce costs and environmental risks associated with liquid chemical handling.
Area of Science:
- Environmental Science
- Radiology
Background:
- X-ray film processing generates pollution from photo chemicals and rinsing water.
- Traditional methods contribute to environmental contamination and incur significant costs.
Purpose of the Study:
- To evaluate a novel X-ray film processing system designed to minimize environmental pollution and reduce costs.
- The system utilizes solid photo chemicals and a water recirculation method for rinsing film.
Main Methods:
- Water consumption, processor function, image quality, and archivability were measured before and after system implementation.
- Waste-silver content in rinsing water was also analyzed.
- The efficiency of solid chemicals and mixers was assessed.
Main Results:
- Water consumption decreased by 88% with the implementation of a simple rinsing water recirculation system.
- Silver-contaminated wastewater discharge into sewers was eliminated.
- Image quality and archivability (over 100 years) remained high.
- Solid photo chemicals proved efficient, maintaining stable, high-standard image quality and reducing pollution risks.
Conclusions:
- A simple rinsing water recirculation system substantially reduces water consumption and environmental silver contamination.
- On-site preparation of photo chemicals is a viable and cost-effective method for film processing.
