ABSTRACT:
A process and apparatus for removing suspended matter from suspensions by filtering through foams, in which the suspended matter retained in the foam (polyurethane foam produced by foaming with water vapor being preferred) is substantially flushed out by expressing the liquid held in the foam, and is removed as a concentrate. This for the the first time permits the removal of suspended matter from continuously flowing suspensions without the flow of the suspensions having to be interrupted in order to clean the filtering means.
