Filtration is a necessity for electrodeposition, pretreatment, and source water treatment systems. Many options are available to maintain cleanliness levels in the fluid systems. Methods such as hydrocyclones, magnetic separators and filter presses provide coarse filtration, while filter roll media, disposable filter bags and ultrafiltration provide finer filtration. Different methods can be used together to provide optimal fluid conditions. Conference GOLD sponsors: Axalta Coatings Systems, BASF Corporation, George Koch Sons, LLC, PPG, Therma-Tron-X Inc.
