<p>Processor for purifying potable water from a spring or mains supply" of the type designed to process water of variable composition to re-establish it with a stable and controlled mineral composition, characterised essentially because water from various origins, such as a spring or the mains itself, passes first through a filter (1) for particles of average calibre, then passing if necessary through a unit to remove disinfecting chlorine (2), then passing through a calcium removal unit (3), then being led through conduits to a double membrane reverse osmosis unit (12) and then to a total filter unit (14) from which it is obtained finally highly demineralised and purified. Next the water is directed to a mineralizing unit (16) capable of adding to it certain quantities of chlorides and/or sodium sulphates, calcium sulphate or other similar compounds, in order to mineralize this water under control.</p> |
