Abstract
The invention proposes a process of in-line mineralisation of water according to which demineralised water is circulated in a pipe inside which enzymes are immobilised to catalyse the reaction of carbon dioxide and water to form bicarbonate, carbon dioxide is introduced into the pipe, and a pre-determined quantity of solid minerals, preferably magnesium and/or calcium carbonate, is introduced into the circulating water. The process enables to accelerate the dissolution of carbon dioxide in the water, which optimises the dissolution of minerals for in-line mineralisation of water, i.e. without stopping the circulation of water. The invention also proposes a system for implementing the process.
Claims17
A process of in-line mineralisation of water, comprising the steps of:
- circulating demineralised water through a chamber comprising hollow fibres onto which carbonic anhydrases are immobilised;
- bubbling CO2 through said chamber, said carbonic anhydrases catalysing the reaction of CO2 and water to form bicarbonate;
- and
- downstream from said chamber, introducing a quantity of minerals in the circulating demineralised water through at least one mineral column, thereby complementing the mineral content of said demineralised water, wherein the process is a continuous in-line process wherein the demineralised water circulates continuously from the chamber to the at least one mineral column without being stored in an intermediate tank for treatment.
A re-mineralisation system for demineralised water, comprising a pipe for circulating water from an inlet to an outlet along which the following are placed:
- means for introducing carbon dioxide into the water, said means comprising a chamber with an inlet and an outlet for CO2, a first anastomosis compartment, several or a bundle of hollow fibres extending along said chamber and a second anastomosis compartment, wherein carbonic anhydrases are immobilized onto said hollow fibres, said carbonic anhydrases catalysing the reaction of carbon dioxide and water to form bicarbonate;
- and
- downstream from said means, at least one mineral column to complement the mineral content of said water, wherein the pipe provides for a continuous in-line flow path directly connecting an outlet of the chamber to an inlet of the at least one mineral column without an intermediate storage tank therebetween.
