    Inerting

    Prior to feeding slurry into the agitated Nutsche filter or filter dryer the vessel interior is inerted by a controlled displacement of the oxygen containing atmosphere with Nitrogen. This procedure prevents the potential formation of an explosive atmosphere in the vessel interior.

    The washing liquid is evenly distributed over the entire filter cake surface using a wash ring with spray nozzles. By again pressurizing the vessel interior the washing liquid is forced thru the filter cake, displacing any remaining mother liquor and is discharged the same way as the mother liquor during the filtration.


    In the reslurry washing process the washing liquid is added to the vessel and mixed with the filter cake using the agitator. By again pressurizing the vessel interior the washing liquid is forced thru the filter cake, displacing any remaining mother liquor and is discharged the same way as the mother liquor during the filtration.
