ABSTRACT:
A system and method are provided for separating water from a solvent during dry cleaning. Included is an inlet capable of receiving a mixture of dry cleaning fluid and water from a basket of a dry cleaning apparatus. The dry cleaning fluid includes a siloxane composition. Also provided is a flow controller for urging a flow of the mixture received from the outlet. Coupled to the flow controller is a coalescent media that receives the mixture urged by the flow controller. A chamber is coupled to the coalescent media for receiving the mixture from the coalescent media to separate the water and the dry cleaning fluid. Also coupled to the chamber is an outlet to remove the dry cleaning fluid from the chamber in the absence of the water.
