related to a plant encountering high BOD/COD loads from a rinse step in a
latex coating process.
A few years ago, under the aegis of the NICE 3 program, PPG, hardly a small
company, but nonetheless working with similar kinds of waste streams, used
reverse osmosis/UF to recover rinse water from a similar paint-laden rinse
stream. This case is useful primarily because it's been written up fairly
well; you can get background info from
I suspect a lot can be done w/ process debugging as well, but would have a
hard time making many suggestions without seeing the actual facility.
Hopefully the PPG case will provide some inspiration.
Hope this helps.
