METHOD OF SEDIMENT DEHYDRATION Russian patent published in 2013 - IPC C02F11/12

Abstract RU 2493112 C1

FIELD: chemistry.

SUBSTANCE: invention relates to dehydration of water-containing material, in particular, sediments of sewages. Method of sediment dehydration includes expression of sediment by vacuumisation of sub-layer space in pulse mode with application of receiver and fast-acting valve until moisture starts boiling in deep layers and migrate to the surface with simultaneous heating of expressed sediment by sucking of heated air or inert gas through layer of sediment and its following double-side vacuumisation.

EFFECT: method makes it possible to reduce moisture-content of sediment and speed up dehydration.
