  • Device and process for electrodialysis of ultrafiltration premeate of electrocoat paint
    Patent number: 7108772
    Abstract: An electrodialysis cell (40) suitable for removal of paint solubilizer from electrocoat paint ultrafilter permeate includes a tubular, non-conductive housing (42), a substantially cylindrical, hollow object electrode (48) in the housing, a substantially cylindrical counter electrode (52) situated within the hollow object electrode, and a tubular ion exchange membrane (50) around the counter electrode but spaced from the counter electrode as well as the object electrode. The counter electrode and the tubular membrane together define an annular electrolyte passageway while the object electrode and the tubular membrane together define an annular ultrafilter permeate passageway. The object electrode-to-counter electrode area ratio is at least about 6.
