Method and apparatus for recovering and purifying a solvent used in an
article cleaning appliance are provided. The method allows passing
solvent-based cleaning fluid from a wash basket through a coarse filter
configured to remove relatively large particulates from the cleaning
fluid. The method further allows passing cleaning fluid from the coarse
filter through a particulate filter configured to remove relatively fine
particulates from the cleaning fluid. An aqueous phase that may be
present in the cleaning fluid is separated by decanting and coalescing
through a separator/filter assembly. The cleaning fluid may then be
passed through a regeneration cartridge for removing any water that may
remain in the cleaning fluid, and for adsorbing organic contaminants that
may be present in the cleaning fluid. Recovered solvent may be stored in
a tank for subsequent use in a cleaning process performed by the
appliance.
