The inventive method for reconditioning a household ion-exchange cassette for filtering a drinking water and device for removing nitrates from drinking water relate to water filter cleaning and to cleaning, regenerating and disinfecting ion-exchange fillers. The method for reconditioning a household filtering cassette consists in regenerating the cassette ion-exchange filler by filtering a 10 % table salt solution and in disinfecting by boiling water, wherein said reconditioning is regularly repeatable at least one time each two weeks. The inventive drinking water ion-exchange filter comprises a container provided with brackets and a funnel, which is arranged thereon and has an opening for receiving a cassette. Said cassette and the filler thereof which occupies the entire volume of the cassette are made of a heat-resistant materials withstanding a temperature of at least 100 °C. Several hard balls made of an inert material are placed in the ion-exchange filler. The container can be provided with a heating element. The device for removing nitrates from water consists of said filter, a cylinder for measuring a salt quantity and a nitrate sensor. |
