Reviewed Printing-Pre-press Operations Options
Options below have reviewed by pollution prevention specialists. They are commonly recommended and implemented
for facilities. |
| |
| Use Chemical Substitutes for photographic films |
| A non-silver substitute may be an option. |
| |
| Use Electronic Imaging that has Editing Capabiliti |
| Use electronic imaging to reduce multiple steps involved in photodeveloping |
| |
| Implement a Chemical Inventory Program |
| Track inventory to utilize photodeveloping chemicals, paper, and film before their expiration. |
| |
| Change Operational and Work Practices |
| Implement changes to reduce chemical use in spent chemical and heavy metal recovery and recycling. Some possible steps towards this goal include: reducing chemical bath contamination, counter current washing, filtrating screen making wastewaters to remove particulates, recycling plates and plate materials, or returning plate materials to the manufacturer or to a metal recoverer.
|
| |
| Use Alternative Chemicals |
| Eliminate the need for pretreatment if wastewaters are being discharged into the sewer by using water-developed lithographic plates and film instead of solvents in processing. |
| |
| Substitute bleaches |
| Substitute Iron-EDTA bleaches for ferrocyanide bleaches
This modification may eliminate particular treatments and disposal requirements
|
| |
| Use a washless processing system |
| Implementing this technology is expensive, but will reduce wastewater by as much as 97%
|
