Cartridge for purification of water by electroactive adsorber material (Zeta potential)

Abstract

An apparatus for purification of water comprises a housing (4) having an untreated water feed (5) and a cartridge (10) inserted in the housing (4) which comprises: - a first ply (1) made of an electroactive adsorber material having an electrokinetic potential (zeta potential) in an aqueous environment at which microorganisms, in particular viruses and bacteria, present in the water accumulate by electroadsorption, - a second ply (2) made of an electroactive adsorber material, having an electrokinetic potential (zeta potential) in an aqueous environment, at which microorganisms, in particular viruses and bacteria, present in the water accumulate by electroadsorption, - and a third ply (3) arranged between the first ply (1) and the second ply (2) which contains an adsorbent at the surface ofwhich particles or dissolved substances present in the water accumulate by physical and / or chemical adsorption, - wherein the plies (1, 2, 3) are each configured as a hollow cylinder and are arrangedconcentrically with respect to one another with the first ply (1) radially outermost and wherein arranged between the inside of the housing (4) and the radially outermost first ply (1) is an annularchannel (8) in communication with the untreated water feed (5) for distribution of the untreated water in the cartridge (10). This apparatus allows simultaneous purification and disinfection / sterilization of water and both inorganic or organic impurities, for example trace substances and endocrine disruptors and also microorganisms, can be removed from the water.

Description

technical field [0001] The invention relates to a device for cleaning water. Background technique [0002] For cleaning or purifying water, especially drinking water, various filters are known from the prior art. By means of the water filter, for example, turbidity, microorganisms and undesired substances dissolved in the water can be removed, or at least their concentration can be reduced. Here, there is a difference between water filters which either remove particles contained in the water from the water mechanically, for example by screening techniques, or use chemical-physical Substances in the water. e.g. mesh filters or permeable filters with permeable filter membranes of preset pore size, e.g. micro-, ultra- or nano-filters, reverse osmosis modules or filters with particle filter media, e.g. gravel filtration filter, stone filter or sand filter, are all water filters that mechanically remove particles from the water. Particles with a particle size in the range of ...

AI Technical Summary

Problems solved by technology

There is a particularly high risk of contamination if the activated carbon in the activated carbon filter is not continuously flowed through by the raw water, since a moist environment is formed on the surface of the activated carbon, which provides ideal conditions for the growth of germs

For these reasons, activated carbon-based adsorption filters, although extremely suitable for removing trace substances, microhazardous substances and endocrine disruptors from water, nevertheless carry a high risk of contamination
