Description

The The invention relates to a disposable filter cartridge for the Water treatment and a device device for the use of the same - especially for drinking water treatment in household and building engineering.

The Treatment of water, especially of drinking water is a worldwide Topic and in particular dependent on the local supply, quite different in different parts of the earth or country can be. But also in the so-called civilized countries The drinking water extracted from the soil increasingly suffers Impairment by groundwater lowering and pollution such as As by fertilizers and other chemical contaminants. For this purpose, a domestic or building services Preparation of drinking water recommended that the disadvantages of existing Devices and equipment tries to improve. Problematic is certainly the metrological coverage of the offered Water quality - especially in domestic Environment - because the investigations are relatively complicated shape. The metrological detection also applies on the quality / condition of filters on existing equipment and facilities, if not intended Use.

One Water filter is a device for cleaning the water to z. B. certain substances or microorganisms from the water remove or reduce their concentration in it. Mostly lies the filtering of water is a passive mechanical barrier for the substances to be filtered at the same time permeability of water. Known filter principles are activated carbon filters, ion exchange filters, Granule filter and reverse osmosis filter.

By The activated carbon filter is a physical water purification achieved. The activated carbon has a large internal surface and thus has a good absorption capacity as well for harmful substances, such as high molecular weight Substances such. As dyes, proteins, etc. The activated carbon can treated with bactericidal silver. The activated carbon However, it goes into saturation, there will be no more Material absorbed, water flows freely through the Filter or removes removed substances from the filter with in the drinking water.

through an ion exchanger can selectively ions of heavy metals be removed; the filtrate is less mineral and less hard, but a little more acidic. The ion exchange takes place on the surface of synthetic resin balls; Minerals like calcium and magnesium, but also dissolved lead and copper - all cations - become held in exchange for hydrogen ions.

Known are drinking water filter applications with activated carbon and silver addition or on ion exchange substrate based cartridges, wherein a Jug is filled with tap water and filtered water is discharged during pouring, the filter performance not obvious.

Also higher quality filter systems are used, the activated carbon in separate cartridges with ion exchangers to remove lime or combine nitrate or homogeneously pressed activated carbon blocks for direct connection to the domestic water pipe. Other systems combine activated carbon filters with one irradiation with UV (ultraviolet) light or consist of a multi-level Reverse osmosis system.

• – auf der einen Seite entsteht ein Konzentrat
• – auf der anderen Seite entsalzenes Wasser, auch Permeat oder Reinwasser genannt.

Reverse osmosis uses the natural tendency to equilibrium; Water molecules penetrate a membrane from the saline to the low-salt side

• - On the one hand, a concentrate is produced
• - On the other hand desalinated water, also called permeate or pure water.

there builds up a pressure difference, the osmotic pressure; arrives Pressure far above the osmotic pressure available is the process reversible, the reverse osmosis.

All Filter systems pose the risk of contamination when used or used cartridges; In addition to the activated carbon dust can also silver from the cartridge be rinsed. To the same extent as calcium, Copper, nitrate and other ions from the water are filtered or neutralized sodium and / or chloride is added to the water.

How out 1 can be seen, there is the filter cartridge 10 from a three-dimensional, preferably cylindrical arrangement with a multilayer structure, wherein the geometries of the structure are shown only by way of example and not necessarily cylindrical. The filter cartridge consists of the two porous outer shells, the fleece upper part 11 and the fleece bottom 15 , They have the task of acting as a solid filter - for pre- and post-filtration. The non-woven top is to prevent solids from entering the filter cartridge or should achieve that solids from the pressurized water 41 be filtered out. The nonwoven base prevents solids from the filler of the cartridge in the drinking water 42 reach. As a filter material for the solid filter various porous materials can be used, such as. B. x micron polypropylene (PP), x <5 and / or x <1. Furthermore, the two porous outer shells in each case to the middle open half shells -. B. as a deep-drawn / praline box - for receiving filter filler.

The cavity of the porous outer shell - fleece upper part 11 - Is made with a shaped according to the geometry specification tablet of activated carbon 12 filled. The activated carbon reduces odor and / or taste-disturbing substances, such as chlorine and chlorine compounds. Additives of silver have a bactericidal effect. Because of the disposable application of the filter cartridge and the further filtering in the fleece lower part 15 Silver and activated carbon dust can not enter the filtered drinking water 42 escape.

The activated carbon can be inserted instead of tablet form as granules, since the space available for this through the membrane film 13 is completed. The membrane of certain porosity filters out heavy metals and also organic contaminants.

In the forming cavity between the membrane film and nonwoven base is with a mineral tablet 14 filled. The mineral tablet prepares the water, such. As by flavoring agents, these substances can be versatile and thus also a variant formation produced and offered filter cartridges. Again, the mineral filler can be given as granules in the filter cartridge instead of in tablet form.
