| 20080237152 | CARTRIDGE SEPARATOR FOR IMMISCIBLE LIQUIDS - A separator of the present invention provides a means for separating a immiscible dispersion of at least one oil from water. The separator adapted for use with a flow generator, includes a housing, a coalescing cartridge within the housing, the cartridge retains a coalescing media and defines at least one cavity or passage, permitting flow of the dispersion into and out of the passage; and a flow regulator comprising a constriction and the regulator displaceable between an open and a closed position and permitting liquid flow out of the passage when in the open position. The separator allows a greater throughput of coalesced oil/water dispersions through the separator due to removal during of coalesced oil and clarified oil during regular operational mode and the backwash mode, and further permits the use of the incoming or non-coalesced dispersion for backwash mode | 10-02-2008 |
