Abstract: Methods and compositions for removing a targeted constituent from water are disclosed. The water including the targeted constituent may be transported into a reactor and the reactor may include a magnet and zero valent iron particles. The targeted constituent can chemically react with the zero valent iron particles and the particles may then be attracted to the magnet. The water may then pass out of the reactor free of the targeted constituent. Additionally, the zero valent iron particles may be regenerated and reused.

Abstract: The present disclosure relates to purge fluids, methods of using the purge fluids, and systems to be used for recycling the purge fluids. In some aspects, the purge fluid may be used to clean or purge an automated spray coating apparatus, such as a paint gun. The purge fluid may include a solvent and water. After the purge fluid is utilized for purging or cleaning certain system components, the purge fluid may be treated, subjected to a liquid-solid separation technique, and reused as a purge fluid.
