The present invention relates to the process of re -mineralizing treated potabi.epsilon. water that has had hardness components removed by dissolving a magnesium compound in the treated water. The resulting concentration of magnesium, pïi level and alkalinity level are controlled by the inclusion of a calcium compound such as calcium carbonate and a bypass orifice. The bypass orifice allows a portion of pretreated wafer to bypass a filter that contains the magnesium compound. The process is particularly useful as an in-line process for continuous or semi-continuous treatment of water. The preferred magnesium and calcium compounds include magnesium phosphate dibasic t.pi.hydrate and calcium carbonate, respectively.
La présente invention concerne un procédé de reminéralisation dune eau potable traitée dont les composants de dureté ont été éliminés, ledit procédé consistant à dissoudre un composé de magnésium dans l'eau traitée. La concentration de magnésium, le niveau de pH et le niveau dalcalinité qui en résultent sont régulés par lincorporation dun composé de calcium tel que le carbonate de calcium et dun orifice de dérivation. Lorifice de dérivation permet à une partie de leau prétraitée de contourner un filtre qui contient le composé de magnésium. Ce procédé est particulièrement utile en tant que procédé en ligne permettant le traitement continu ou semi-continu de leau. Les composés de calcium et de magnésium préférés comprennent respectivement le phosphate de magnésium dibasique, trihydraté, et le carbonate de calcium.
