METHOD AND APPARATUS FOR REDUCING EXPOSURE nanoparticles activated carbon in a mixture of water and ethanol

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to water treatment. Proposed method consists in that alcohol-water mix to be cleaned is forced into adsorber column bottom filled with activated coal powder while cleaned alcohol-water mix is bled from adsorber column top. Prior to used, pelletised or ground activated coal in adsorber is subjected to sizing to wash granules or particles smaller than 1 mcm therefrom. Washing fluid is fed to adsorber column top via hydraulic vibrator generating longitudinal hydroacoustic waves in wide range of frequencies while used washing fluid is discharged from column bottom via membrane filter with sizes of pore varying from 1 to 3 mcm. Besides, rate of flow of said mix is set 10 to 100 times higher than that during filtration in adsorber in working conditions.;EFFECT: decreased probability of ingress of nanoparticles.;4 cl, 2 dwg, 2 ex
