Abstract:
A method for providing purified, re-mineralized water (127) in magnesium and calcium ions comprises the steps of providing a flow of feedwater (101) and purifying and/or demineralizing it by a purifying and/or demineralizing process to produce a flow of purified, demineralized water (113); injecting carbon dioxide into said purified, demineralized water (113) to produce a flow of carbon-dioxide-enriched water (123); and finally passing the carbon-dioxide-enriched water (123) through a re-mineralizer (124) which comprises a dolomite medium (126), thereby producing a simultaneous remineralizing of the water in Calcium and Magnesium leading to a flow of purified, re-mineralized water (127).
Abstract:
The invention relates to a process for producing magnesium and/or calcium-enriched drinking water based beverage, comprising: preparing a concentrated aqueous solution of magnesium and/or calcium bicarbonate by, a) providing a powder of magnesium and/or calcium compound in a reactor (4); b) adding an aqueous liquid in said reactor; and c) injecting carbon dioxide (CO2) into said reactor; adding at least part of the concentrated aqueous solution of magnesium and/or calcium bicarbonate into a flowing circuit comprising an aqueous liquid. The invention also relates to the associated manufacturing apparatus comprising a reactor.
Abstract:
The present invention provides a filter unit 10 for a capsule for preparing a beverage and/or nutritional product. The filter unit is designed to avoid clogging. The filter unit therefore comprises a second filter 50, which is provided upstream a first filter 40 in respect to the liquid flow through the filter unit 10. The second filter 50 has a pore size to hold back large particles such as scale, bio-film or iron oxide. The present invention is able to ensure a consistent liquid flow through the filter unit. The filter unit can be used with any kind of liquid source.

Abstract:
An apparatus for purifying liquid comprises a substantially tubular irradiation chamber (100) and a plurality of UV-LEDs (110) projecting ultraviolet radiation into it so as to irradiate the flow (106) of liquid being passed through it, where each of the UV-LEDs (110) is disposed upon the irradiation chamber (100) so that it is illuminated by at least one other of the plurality of UV-LEDs (110).
Abstract:
The invention relates to an irradiation chamber (300) for a liquid purification apparatus using ultraviolet light irradiation against the reproduction of pathogenic microorganisms, comprising an inlet portion (302), an outlet portion (303), and a main portion (301) having an elongated shape, the irradiation chamber (300) having an internal surface defining an cavity, the irradiation chamber (300) being provided with ultraviolet light emitting means configured to irradiate liquid in the irradiation chamber (300) with ultraviolet light, the main portion (301) having a shape enlarged compared to the inlet portion (302). The internal surface of the irradiation chamber (300) defining the cavity is a three dimensional rounded surface, having no edge which forms a recess. The invention also relates to a liquid purification apparatus and to a beverage dispenser.
Abstract:
An apparatus (100) for purifying liquid comprises an irradiation chamber (102) upon which are disposed a plurality of UV-LEDs (112) which irradiate a flow (110) of liquid as it passes therethrough; a coolant conduit (104) is disposed about said irradiation chamber (102) and UV-LEDs (112), which conducts a flow (126) of a coolant fluid through it thereby cooling the flow (110) of liquid and the plurality of UV-LEDs (112).
Abstract:
The invention concerns a production process of a zinc enriched drinking water, also called final water product, which, starting from a water matrix comprising drinking water, comprises, a first step of: Measuring the pH of the water matrix (step A), and then, in one order or the other, the steps of: Acidifying the water matrix (step B) in order to get a final water product having a pH lower than 7, and Adding zinc (step C) in a concentration comprised between 0.8 mg/l et 5 mg/l, so that sedimentation of zinc in the final water product is lower than 10% of soluble zinc over a period of 12 months at a maximum temperature of 40° C. The invention also concerns a zinc enriched drinking water composition and packaged zinc enriched drinking water.

Abstract:
The invention relates to a liquid purification assembly using ultraviolet light irradiation against reproduction of pathogenic microorganisms, comprising an irradiation chamber (200) having an internal volume and comprising an inlet (204) and an outlet (205), the irradiation chamber (200) being provided with ultraviolet light emitting means (208) configured to irradiate liquid in the irradiation chamber (200) with ultraviolet light. The irradiation chamber (200) comprises a mechanism configured to cause a change in the internal volume of the irradiation chamber (200), said change in internal volume drawing liquid into the irradiation chamber (200) when the volume of the irradiation chamber (200) increases, and forcing liquid out of the irradiation chamber (200) when the volume of the irradiation chamber (200) decreases. The invention also relates to a beverage dispenser and to a method for purifying a liquid.
