If the material being dissolved in water is ion, the ion that can be also carried out by using ion exchange material Exchange removes the ion from water.Furthermore it is possible to by means of the Electro Sorb that is carried out at electroactive material by electrostatic charging Particle removed from water, i.e. such as microorganism, the microorganism is usually negatively charged, which has in aqueous environments ZETA potentials, especially the ZETA potentials of positive electricity.
A kind of electroactive sorbing material for adsorbing microorganism from water is disclosed from 03/000407 A1 of WO.Electricity Active adsorbing material is electropositive composite material for weaving, which includes nano alumina particles or nano oxidized The mixture and underlying structure of aluminum fiber, such as the carrier structure based on glass fibre.Since composite material for weaving is in aqueous ring Electropositive ZETA potentials in border, the sorbing material can remove static removal band negative electricity from liquid to be cleaned by Electro Sorb Particle.Known electroactive sorbing material is for example arranged on the surface of diaphragm from 03/000407 A1 of WO, or is used as For filter layer, and liquid to be cleaned, especially water guiding pass through diaphragm or filter layer.Here, electronegative particle, especially Microorganism of the grain size less than 1 μm is engaged on the adsorbent material by Electro Sorb.By known sorbing material, more particularly to from Microorganism, especially virus and bacterium are removed in water, to sterilize to water.It is well known, however, that electroactive sorbing material be unsuitable for Except uncharged particle.
From the nineties, the endocrine activity substance in waters causes science and the interest of the public.Endocrine activity object Matter is can to influence and interfere the movable substance of the normal hormone of human and animal.If the influence of endocrine activity substance causes Hormone system is impaired, then these substances are also referred to as incretion interferent.This incretion interferent can be naturally occurring Or be also to be synthetically prepared.The endocrine disruption that partly can detect in food and feed and especially drinking water The example of object includes pesticide, dioxin, PCB and bisphenol-A (BPA).Incretion interferent can also be by including endocrine activity The drug of substance, for example, contraceptive, anodyne, thyroid hormone substitute or x-ray contrast agent are via family or medical waste water In being recycled into water.In general, comprising these substances in water as incretion interferent with the range of every liter of g or ng of μ In minimum concentration work.
In order to go water removal in endocrine activity substance or other organic or inorganic impurity, i.e., for example micro substance and/or Trace contaminant can use based on sorbing material, i.e. the water filter of such as activated carbon.In 10 2,013 006 711 A1 of DE In disclose a kind of for method and filter plant based on adsorption filter processing or purified water, which includes Sorbing material based on activated carbon.Wait for that the inorganic or organic impurities removed from water is incorporated in adsorption material by physical absorption herein On material, to be removed from water.However, in the case of using sorbing material in water filter, exist in sorbing material Germ shapes or the risk of proliferation, this can result in the undesirable pollution to filtered water.
Mainly it is observed that the microbial contamination of sorbing material in the adsorption filter based on activated carbon.There, May there are the microorganism being suspended in drinking water, such as bacterium, virus and also have a small amount of fungi to be colonized in adsorption material once in a while On material.For example, after the relatively short duration of operation, active carbon particle can also be coated with by microcolony and entire biomembrane In fixed bed filter.According to the nutritional ingredient of raw water, various forms of biomembranes are may be constructed.Microorganism is in this absorption The good of active carbon filler for being provided with relatively large gap in filter the reason of fast propagation passes through means.In addition, embedding The microorganism entered in this biomembrane also can：Made using the compound being adsorbed in the activated carbon from water to be filtered For nutrient source.If this substance gathers on the adsorbent material after the filter long period runs, this can be additionally Promote the development of biomembrane.If the activated carbon in active carbon filter is not flowed by raw water constantly, exist especially big Pollution risk be proliferated for germ because foring moist environment on the surface of activated and provide ideal condition. For these reasons, the adsorption filter based on activated carbon is although be excellently suitable for removing micro substance, micro- nuisance from water Matter and incretion interferent, however carry higher pollution risk.
