  • Process for dewatering zeolite suspensions
    Patent number: 4545969
    Abstract: In the treatment of a zeolite suspension to separate solids from the mother and/or washing liquor, a vibrator is used in the suction drying zone of a vacuum filter in order to partially liquefy the filter cake material through the introduction of shear forces into the solidified filter cake, so that further separation of the pure liquid phase can take place in the suction drying zone of the vacuum filter.
