Definitions

  • the invention relates to a device for water treatment with a hydraulic unit and with a filter unit.
  • the hydraulic unit has a water inlet for water to be treated and a water outlet for removal of the filtered through the filter unit, treated water.
  • the filter unit comprises a plurality of filters and is detachably connected to the hydraulic unit.
  • the device is supplied in particular drinking water, the quality of which is further improved by the filters contained in the device.
  • the invention further relates to a corresponding filter unit.
  • Water treatment systems are known in which individual filters are connected in series with one another via hose connections. To replace the filters, they must be disconnected from the hose connections at the location of the water treatment system and then new filters connected. A filter change is thereby very time consuming and error prone.
  • water treatment device of the type mentioned developed.
  • several filters are arranged in a single filter cartridge in a row.
  • Water introduced into the hydraulic unit is first supplied to a water inlet of the filter cartridge, then passes through the filter cartridge and then leaves the cartridge through a water outlet before it is ready for removal at a water outlet.
  • the filter cartridge is detachably connected to the hydraulic unit, ie the filter unit can be separated as a whole from the hydraulic unit, removed from the device and then a new filter unit re-inserted into the device and connected to the hydraulic unit.
  • a disadvantage of such devices is that the water to be treated always passes through the individual filters of the device in a predetermined and unchangeable order.
  • the hydraulics of the device can not be varied and adapted to different situations.
  • the invention has for its object to provide a device for water treatment of the type mentioned, in which the aforementioned disadvantages are reduced.
  • the device comprises a water-conducting interface arrangement with a first, the hydraulic unit associated interface and a to this complementarily formed further, the filter unit associated interface.
  • the interface arrangement has more than one water inlet from the hydraulic unit into the filter unit and more than one water outlet from the filter unit into the hydraulic unit.
  • an activated carbon filter used in the filter unit can be excluded from the disinfection by a bypass for the duration of the disinfection. Otherwise the hydrogen peroxide solution would destroy the activated carbon filter.
  • This also allows physical parameters of the water to be treated in the hydraulic unit to be selectively changed and adjusted by suitable means before the water is fed to a filter of the device. The quality of the water treatment is thereby improved.
  • the filters are individually interchangeable connected to the filter unit.
  • the assembly of the filter unit with filters can be individually configured and also subsequently changed.
  • An individual adaptation of the filter unit to the quality of the water to be treated and to the desired quality of the treated water is thereby possible.
  • the filters are connected via water pipes to the further, the filter unit associated interface and at least one water pipe is detachably connected to at least one filter and / or connected to the other interface.
  • the device has a membrane filter and a water inlet to the membrane filter, a Nutzwasserablauf for treated by the membrane filter water and a water drain for used for cleaning the membrane filter water.
  • the membrane-filtered water leaves the membrane filter through the utility water drain. Part of the water fed to the membrane filter water is passed over the surface of the membrane filter and fed to the wastewater drain. Impurities deposited on the membrane filter surface are entrained by the flow of the water passed on the membrane filter surface and disposed of via the waste water outlet. The membrane filter is thereby cleaned without having to remove the membrane filter from the device.
  • the ratio of the water supplied to the membrane filter and the water leaving the membrane filter via the waste water outlet is preferably by means of valves and throttling elements adjustable and adaptable to the individual contamination of the water to be treated and to the degree of contamination of the membrane filter.
  • the membrane filter is arranged in the hydraulic unit.
  • the device has at least one booster pump, which increases the pressure of the water to be treated, before the water is fed to a downstream filter.
  • a booster pump is positioned between a sediment pre-filter and a downstream membrane filter.
  • the sediment pre-filter requires a lower water pressure than the membrane filter for an optimal filter result.
  • the device has a safety device which closes a valve in the water inlet of the hydraulic unit at a separation of the filter unit from the hydraulic unit and interrupts the power supply to the hydraulic unit. This embodiment ensures that When removing the filter unit from the device undesirable water escapes from the first, the hydraulic unit associated interface.
  • the device has a tank for storing treated water and the interface arrangement is arranged higher relative to the earth's surface than the maximum filling level of the tank. This configuration ensures that water that has not already been treated undesirably escapes from the tank through the first interface associated with the hydraulic unit when the filter unit is separated from the hydraulic unit.
  • the device has a circulation water line, which leads out of the tank and back into the tank, wherein the water outlet of the hydraulic unit is connected via a valve to the circulation water line and in the water flow of the circulation water line a Nachentkeimungsfilter is arranged ,
  • the post-sterilization filter is particularly preferably formed by a ceramic filter.
  • the post-sterilization filter is arranged in the filter unit.
  • a simple replacement of Nachentkeimungsfilters is possible together with the other filters of the filter unit.
  • one or more pre-filters selected from the group of sediment pre-filters, softener filters and / or activated carbon filters, then a membrane filter and finally a ceramic filter connected in series with each other in the device.
  • This filter combination ensures optimal purification of the water to be treated for a variety of drinking water qualities to be treated, which are supplied to the device.
