Abstract
Waste developer used for the development of pigment-containing non-silver-salt photosensitive materials is disposed of by filtering through a filter which does not allow pigment particles to pass through and allows the waste developer solution to be treated to flow horizontally to the surface of the filter membrane. The solution which passed through the fiber membrane is reused as a developer. This process greatly decreases discharge of waste developer allows a long-time stabilized continuous developing process.
Claims5
A process for disposing of a waste developer used for the development of pigment-containing non-silver-salt photo-sensitive materials, comprising subjecting the waste developer to a separating treatment by a filter means which does not allow pigment particles to pass through and allows the waste developer solution to be treated to flow horizontally to the surface of a filtering membrane, and reusing the obtained solution which passed through the filtering membrane as a developer.
