  • Dissolved air flotation use with cationic metal processing fluids
    Patent number: 11230476
    Abstract: In an effort in solving the difficulties with cleaning cationic metal processing fluids and/or emulsions, processes for cleaning a metal processing fluid which is substantially free of fatty acids is provided herein and includes treating the metal processing fluid with dissolved air floatation. Also provided are processes for deforming metals and removing suspended foreign matter from a contaminated metal processing fluid and/or emulsions which are substantially free of fatty acids is provided and include the use of DAF technology. In one embodiment, the process is performed in the absence of a filter. In another embodiment, the process is performed in the absence of a filter which is capable of removing suspended foreign material in the contaminated metal processing fluid.
    Type: Grant
