Disclosed is a process for enriching silicate content in drinking water that includes separating raw water via reverse osmosis into a permeate comprising demineralised raw water and a retentate comprising mineral enriched raw water. The permeate is mixed with a water glass solution comprising sodium silicate and/or potassium silicate. An ion exchange process is used to reduce the concentration of sodium and/or potassium ions in at least part of the mixture. At least part of the retentate is supplied to the mixture after reducing the concentration of sodium and/or potassium ions to provide a silicate-enriched drinking water. Also disclosed is an apparatus for producing a drinking water enriched with silicate. The apparatus includes a reverse osmosis unit, a mixing unit, an ion exchanger, and a feed unit for feeding at least part of the retentate to the mixture after reducing the concentration of sodium and/or potassium ions.

The present invention relates to a device (1) for filtering a fluid circulating in a plumbing and heating system, comprising a body (2) defining therewithin a filtration chamber (3) that is destined to have a fluid to be subjected to filtration pass through it. The body is provided with a first inlet/outlet opening (10), a second inlet/outlet opening (20) and a third inlet/outlet opening (30): each of which sets the filtration chamber (3) in communication with the outside of the device and can be associated with a line of the system to receive therefrom, or send thereto a fluid entering or exiting said body of the device. The device operates a passage of fluid through the filtration chamber (3), in a selective manner according to a plurality of operative configurations, from an opening between said first (10), second (20) and third inlet/outlet opening (30) to a further opening between said first, second and third inlet/outlet opening. The device further comprises filtering members (40) housed inside the filtration chamber and interposed between the inlet/outlet openings to perform filtering of the fluid passing through the filtration chamber; the filtering members comprise a mechanical filter (41) arranged in the filtration chamber and structured so as to divide the filtration chamber into a first sub-chamber (A), a second sub-chamber (B) and a third sub-chamber (C), in which the first sub-chamber is in fluid communication, without passing through the mechanical filter, with the first inlet/outlet opening, the second sub-chamber is in fluid communication, without passing through the mechanical filter, with the second inlet/outlet opening, and the third sub-chamber is in fluid communication, without passing through the mechanical filter, with the third inlet/outlet opening.

The UV light decontamination module is arranged in a wall of the tank. The UV light decontamination module includes a light source compartment which is accessible from an external area outside of the tank; and a light transmission member configured to transmit UV light from the light source compartment to a liquid space in fluid communication with aqueous solution stored in the tank. The light source compartment includes a light source to emit UV light through the light transmission member to the liquid space.

A system for infusing hydrogen into water dispensing from a refrigerator appliance includes a tank defining an interior volume no greater than one liter. An electrolysis system includes an anode and a cathode disposed within the interior volume of the tank. The anode and cathode are configured to decompose water within the interior volume of the tank when a voltage differential is applied across the anode and cathode during a hydrogen infusion cycle of the electrolysis system. An audio emitter is configured to emit an audio alert in response to completion of the hydrogen infusion cycle.

A hydrogen gas dissolving apparatus 1 has a hydrogen supply unit 2 capable of supplying hydrogen gas, and a hydrogen gas dissolution module 6 for bringing the hydrogen gas supplied from the hydrogen supply unit 2 in contact with and dissolved in water. The hydrogen gas dissolution module 6 has a supply port 62 to which the hydrogen gas is supplied, a hydrogen chamber 63 communicating with the supply port 62 and filled with the hydrogen gas supplied from the supply port 62, and an exhaust port 64 communicating with the hydrogen chamber 63 and discharging the air in the hydrogen chamber 63. The exhaust port 64 is located in a lower part of the hydrogen chamber 63.

The ozone spray wand is a portable aqueous ozone generator that is adaptable to fit onto garden hoses, backpack sprayers or any other water supply source. The wand uses electrolytic cells to make ozone on-demand. An operator simply pulls the trigger and a solenoid valve starts delivering ozonated water. Embodiments use a rechargeable battery that allows it to operate for 1 hour between recharge cycles. The wand is rated for 500 hours of use which delivers 15,000 gallons of ozonated water.
