SEDIMENT DEHYDRATION DEVICE Russian patent published in 2011 - IPC B01D53/00 

FIELD: process engineering.

SUBSTANCE: invention relates to separation of inhomogeneous fluids into solid and liquid phases using presses combined with filters and may be used for mechanical and electroosmotic dehydration of suspensions, slimes, and active sludge of effluents. Electroosmotic press filter comprises cathode and anode elements to receive DC pulses with variable voltage and current produced in rectifying variable current. DC pulses at electrodes are sequentially alternated with smaller-duration reverse-polarity variable amplitude-and-duration pulses.

EFFECT: higher water molecule mobility toward cathode that reduced dehydration interval.
