METHOD OF RECLAIMING OF GRANULAR FILTER MEDIUM Russian patent published in 1995 - IPC

Abstract RU 2042381 C1

FIELD: reclaiming of filter medium. SUBSTANCE: method consists in delivery of flushing water by ascending- loosening flow (countercurrent flow) at an intensity of 1,5-2,0 l/cm2 and action of acoustic vibrations in the form of jet-pulsating field at an intensity of 0,5-1,0 Wt/cm2 directed towards ascending-loosening flow. The area of action of jet-pulsating field is displaced perpendicular to granular filter medium in the plane perpendicular to ascending-loosening flow at a speed of 3 to 5 m/min. EFFECT: facilitated procedure. 2 dwg
