Abstract
The invention relates to a method and installation for treating water for human consumption, for an industrial process, for agricultural purposes or for other purposes. The method used to remineralize raw water comprises a stage in which carbon dioxide and at least one inorganic base are injected. According to the invention, the method comprises the following stages: the flow Q of raw water is separated into a flow Q1 and a flow Q2; only flow Q1 is remineralized by injecting carbon dioxide and at least one inorganic base, said remineralization being carried out in at least one remineralization basin; remineralized flow Q1 is mixed with untreated flow Q2.
Claims11
Process for remineralizing raw water of the type including a step of injecting carbon dioxide and at least one inorganic base, characterized in that it comprises the steps of:
- separating the flow Q of raw water into a flow Q1 and a flow Q2;
- remineralizing only said flow Q1 by injecting carbon dioxide and at least one inorganic base, the remineralization being carried out in at least one remineralization tank
- mixing the remineralized flow Q1 with said untreated flow Q2.
Installation for the remineralization of water comprising at least one main water supply pipeline (1) and means of injecting carbon dioxide and at least one inorganic base (2, 3), characterized in that it includes at least one by-pass pipeline (4) for a portion of the flow coming from the main pipeline (1), at least one remineralization tank (5) provided on said by-pass pipeline (4), said injection means (2, 3) being provided on said by-pass pipeline (4) and/or on said remineralization tank (5).
