The invention relates to a process for removing nitrates from drinking water in an ion exchanger, according to which in the course of charging an exchanger substance, the nitrate ions present in the untreated water are exchanged for hydrogen carbonate ions and after charging has been completed, ...
Process for removing nitrates and other ions, such as chlorides, sulphates and others, from drinking water, which consists in subjecting the crude water to be purified to a plurality of membrane purification means, particularly within electrodialysis units of the polarity-reversal type, arranged in...

Pollution of groundwater and surface water by nitrates is becoming a common problem for both industrial and developing countries. The concentration of nitrate in many regions in Morocco greatly exceeds the standards for drinking water. Hence, the beneficial or harmful effects of nitrate on human ...
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 ...
