Opportunities and challenges of using ultrafiltration for the concentration of diluted coatings materials
The use of cross-flow ultrafiltration for the recovery of coating ma-terial from aqueous streams started about 30 years with electro deposition paint in the automotive industry. This early success can be related to both environmental and economical advantages of using ultrafiltration. Ultrafiltration recovers and concentrate electro deposition paint on the retentate side and produces purified wate
