LOOSEN FILTERING LAYER FILTER CLOGGING DEGREE DETERMINATION METHOD Russian patent published in 1996 - IPC

Abstract RU 2057572 C1

FIELD: liquids purification. SUBSTANCE: loosen filtering layer filter clogging degree determination method provides for measurement of current value of pressure difference in filter and amount of passed through it liquid, determination of criterion for filter clogging, using multiplying of A and B extended factors calculated as solution of system of two equations, each of which has form: ΔPi=AGi+BG2i

,, that are made from two different of G value modes of filter operation, taken in time interval, during which one can neglect filter clogging degree change, and comparison of obtained result with utmost tolerable value. EFFECT: method allows to draw more accurate determination of filter clogging degree. 2 tbl
