FILTRATION MODULE AND WATER CLEANER (VERSIONS) Russian patent published in 2015 - IPC B01D24/10 B01D27/02 B01D35/27 

FIELD: process engineering.

SUBSTANCE: set of invention relates to drinking water filters, mainly, of gravity type pitcher filters to be used at home. Filter module comprises inlet filter and case filled with filter material, preferably, sorption and softening material, and outlet filter at its bottom. This module ensures optimum water column pressure difference compensation in said case filled with filter material during the entire service life. This allows fluid flows from inlet filter through maximum efficient depth of filter material mainly at a time in lengthwise and crosswise directions to outlet filter. Distance L from any point of fouled fluid inlet to module case via inlet filter to whatever closest point of purified outlet via outlet filter depends on the filter material height H. L should be at least 5% and not over 50% of H, preferably, at least 8% and not over 35%.

EFFECT: higher filtration rate and filter efficiency.
