Definitions

  • the invention relates to an installation system with a sewer and a method for treating, in particular treating, water.
  • the invention also relates to a water treatment cartridge.
  • Water installation systems such as reverse osmosis systems, backwash filters or membrane filters usually all have a concentrate/waste water outlet in the direction of a sewer.
  • Backward contamination can occur here through direct contact with the sewer or, in the case of a free outlet, also through the air.
  • Reverse osmosis systems backflush filters or membrane filters are only listed here as examples.
  • microorganisms such as bacteria, fungi or algae multiplying in the pipes in the water.
  • microorganisms refers to both algae and organisms such as bacteria and fungi.
  • system separators consist of cascaded chambers between which a non-return valve is used in each case.
  • a free outlet the water inlet flows out at a distance from the highest possible non-potable water level, such as with a conventional washbasin. This creates a free flow path that prevents water that has flowed out of the water pipe from being sucked back even if negative pressure forms in the pipe system.
  • microorganisms can also spread through the air and thus get into the concentrate/waste water outlet and multiply here. This can progress to biofilm formation. Therefore, in addition to the risk of microorganisms entering the water from non-drinking water, there is also the risk of so-called reverse contamination.
  • single or mixed populations of microorganisms can form biofilms on surfaces such as the inner walls of tanks or pipes as well as on filters.
  • EPS extracellular polymeric substances
  • the composition of the EPS depends on the species involved in the biofilm.
  • the EPS ensure that the microorganisms adhere to the membrane surface and ensure the mechanical and chemical stability of the biofilm.
  • the filtration performance of the membrane decreases.
  • the increased bacterial growth on the concentrate side can lead to uncontrolled backward contamination in the pipe network.
  • the invention is based on the object of increasing the service life and safety of a water installation system and at the same time reducing the risk of bacterial contamination in the pipe system.
  • the invention aims in particular to provide a device and a method with which contamination on the concentrate/waste water side of a water installation system by microorganisms is to be largely avoided.
  • the object of the invention is already achieved by a water installation and by a method for preventing backward contamination in a pipe network or in a water installation according to one of the independent claims.
  • the invention provides a water installation, in particular a drinking water system, with an extraction point and/or outlet, the so-called “point of use", and an outlet to a sewer, the drinking water system having a flow direction towards the extraction point and the outlet and in the flow direction seen before the expiry has at least one germ barrier.
  • the germ barrier is therefore located on the flow side in front of the sewer.
  • the germ barrier is located in a water-carrying pipe. This is a pipe through which water from a water treatment facility is fed into the sewer.
  • the outlet is in particular designed as the outlet of one, in particular a single, device, such as the concentrate outlet of a reverse osmosis system.
  • the germ barrier is therefore not arranged on or in the sewer, but in a water pipe leading to the sewer.
  • the germ barrier can be arranged in particular in the flow path in front of the outlet, in particular directly in front of the outlet.
  • the germ barrier can be located in the flow path of an outlet, e.g. an outlet on the concentrate side of a reverse osmosis system.
  • the germ barrier can prevent reverse contamination from the sewage system into the water installation.
  • a free outlet can be dispensed with in many applications.
  • the water installation system is also referred to as a "drinking water system" for the sake of simplicity.
  • the drinking water system is fed from a drinking water source.
  • the drinking water system is delimited by an inlet to the drinking water source from which drinking water enters the drinking water system and by the withdrawal point.
  • the drinking water system is preferably an individually manageable component which can be connected to the water supply, for example in the household.
  • the drinking water system can consist of several components.
  • the chemical germ barrier comprises a biocidal contact material.
  • a “biocidal contact material” is understood to mean materials that contact with water have a bactericidal and/or fungicidal and/or algicidal effect.
  • the germ barrier comprises, in particular, an alkalizing and/or oxidizing material.
  • the germ barrier can also have an oxidizing effect, in particular forming an oxidizing substance such as hydrogen peroxide.
  • the formation of biofilms and the growth of algae in a drain of the water installation can be reduced or almost completely prevented compared to devices without a corresponding device.
  • the germ barrier prevents germs or a biofilm from growing through the drain
  • the germ barrier is designed in particular in such a way that water is chemically treated in a section of the flow path in such a way that microorganisms are killed within this section.
  • the germ barrier prevents the growth of germs along a pipeline wall against the direction of flow.
  • the alkalizing and/or oxidizing material contains at least one material selected from the group of carbonates, oxides or peroxides.
  • Calcium carbonate magnesium carbonate, calcium oxide, magnesium oxide, Magnesium peroxide, calcium peroxide, sodium peroxide, potassium peroxide and zinc peroxide and mixtures of at least two of the materials mentioned.
  • a suitable peroxide can be used to increase the pH and release hydrogen peroxide into the water.
  • a cartridge with a UV lamp which fights the germs with ultraviolet light, can also be used as a further germ barrier according to the invention in the flow of the water installation.
  • an outlet of the drinking water system which leads to the sewer, includes a connection assembly for connecting at least one cartridge with a germ barrier.
  • the connector assembly is designed so that the germ barrier can be inserted into the connector assembly.
  • the water treatment device and germ barrier can be exchanged separately from one another. This enables particularly simple handling of the water treatment device and the germ barrier, which allows safe operation and at the same time cost-effective maintenance of the drinking water system.
  • agglomerated materials in which the formation of dust is largely prevented, are easy to handle.
  • the germ barrier comprises an alkalizing and / or oxidizing material having particles whose Particle size is below 5 mm, preferably below 3 mm, particularly preferably in the range between 0.2 and 10 mm, preferably 0.5 mm and 2.5 mm.
  • the particle sizes given above refer to the initial state of the respective alkalizing and/or oxidizing material.
  • the upper limit for the particle size of the material results in particular from the desired dissolution kinetics.
  • the use of powder is also possible within the scope of the invention.
  • the granulated materials selected according to the invention dissolve in water so slowly that the pH value of the water in the cartridge is increased so that the desired biocidal effect can be established. With the help of the invention, the formation of biofilms and the growth of algae can be reduced or almost completely prevented.
  • the alkalizing and/or oxidizing material is configured in such a way that the OH concentration increases in such a way that the pH increases to 10 to 13.
  • All microorganisms have a pH range within which growth is possible, or an optimal pH range. Most natural environments have a pH between 4 and 9 and there are many microorganisms whose pH optimum is in this exact range.
  • the extracellular pH value While the extracellular pH value has an influence on the growth of the bacteria, the intracellular pH value must remain close to neutrality (with the exception of extremely acidophilic or alkaline-philic bacteria) since DNA is an acid-labile structure and RNA is an alkaline-labile structure. If the extracellular pH value is outside the pH optimum or outside the range in which growth is still possible (see table), the bacteria are no longer able to stabilize the intracellular pH value. This slows down or stops bacterial growth or leads to the death of the bacteria.
  • a chemical germ barrier is thus provided in a surprisingly simple manner, the biocidal effect of which is based on the increase in the OH concentration, so that a pH of 10 to 13 is established.
  • the chemical germ barrier can be provided with a housing with an internal volume in the range from 10 mL to 200 mL, preferably an internal volume in the range between 15 mL and 50 mL, and can therefore be extremely compact.
