ABSTRACT:
A novel apparatus and process is provided for removing with a treating fluid surface films that are hydrophilic in nature and comprises a less dense liquid component. The hydrophilic film is removed from non absorbing surfaces such as metal glass and plastics and may contain dissolved solids. The hydrophilic film is substantially immiscible in the more dense cleansing liquid. In a particular embodiment the more dense liquid is a cleansing fluid and the less dense hydrophilic component being present as a contaminant. The apparatus includes a tank (12), a separator chamber (14) and a holding chamber (16). The less dense liquid is removed from the upper part of the separator chamber 14. The configuration of separator chamber (14) effects rapid separation of overflow liquid into an upper layer of the less dense liquid and a lower layer of the more dense liquid. In another embodiment of the apparatus, a second separator chamber (89) and a second holding chamber (90) are included.
