A nitrogen-enriched water generator includes an elongated housing defining a sealed nitrogen/oxygen chamber in which nitrogen molecules are combined with oxygen molecules to form a nitrate (NO.sub.3) or a nitrite (NO.sub.2) gas (NOx gas). The housing includes an NOx gas and water mixing tube, a plasma generator and a nitrogen-enriched water trap. A water spray nozzle sprays water into the chamber. At least one air injection port injects air into the chamber. A vacuum port removes a volume of NOx gas not absorbed by the water from the sealed nitrogen/oxygen chamber.

A urea preparation machine includes a cabinet, a stirring tank, a filtering portion, a water tank portion and a heating portion. The stirring tank is provided in the cabinet. The filtering portion is provided in the cabinet. An inlet of the water tank portion is communicated with an outlet of the filtering portion. The heating portion is provided in the cabinet, the heating portion is communicated with the outlet of the water tank portion, and an outlet of the heating portion is communicated with the stirring tank. The independent heating portion is used for heating water in the water tank portion, then the water heated by the heating portion is conveyed to the stirring tank for preparing urea, through such installation, the heating portion is capable of heating the water in the water tank portion in time.

A mineral spring generator has a machine body and a pipeline disposed in the machine body. Two ends of the pipeline respectively have a water inlet and a water outlet. A solenoid valve is connected between the pipeline. At least two injection channels are connected to the pipeline at intervals along a direction of a water flow in the pipeline. A micromotor is connected between each of the at least two injection channels. An outer end of each of the at least two injection channels is connected to a material container. Each material container is adapted to be filled with a liquid mineral spring concentrate. When the present invention is used, water is inputted through the water inlet, and the solenoid valve and the micromotors are activated to add the mineral spring concentrates in the at least two material containers to different positions of the pipeline.

Plant for washing and sanitising the udders of dairy animals of the type consisting of a control panel (1), for the management and the control of the entire plant, a tank (2) for water collection and delivery, a motor body (3) for plant management and a brush body (4) for animal treatment, characterised in that ozone generator (5), structure for ozone enrichment of the water delivered by said tank (2) and structure for drying the udders with ozone once the washing has been completed and furthermore provided.

A hand held shower head configured to deliver a continuous dose of water dispersed treatment from a water disintegratable treatment source, the shower head including: a hollow body having water inlet opening and water outlet, the water outlet defined by a perforated plate, and a mesh formation disposed within the hollow body between the water inlet opening and the perforated plate, wherein the water inlet opening, hollow body and perforated plate are configured to create in use a pressurised turbulent water flow within the hollow body prior to exiting through the perforated plate, whereby a water disintegratable tablet treatment source introduced into the hollow body prior to use, is then agitated by the turbulent water flow against the mesh in an abrading manner and thereby dispersed into the water flow exiting the perforated plate. A water disintegratable tablet comprising emulsifier, thickening agent, surfactants, oil and rheology modifier is also disclosed.

A nano-bubble generator includes: (i) a housing defining: an inlet for receiving a liquid with entrained macro-bubbles: a first chamber operatively downstream of the inlet; a second chamber operatively downstream of the first chamber; and an outlet operatively downstream of the second chamber; (ii) at least one blade disposed within the first chamber for, in use, cutting macro-bubbles entrained in the liquid to convert such macro-bubbles into micro-bubbles; (iii) at least one first magnet within the second chamber; and (iv) at least one second magnet associated with the second chamber, wherein: (a) the at least one first magnet and the at least one second magnet are arranged such that the polarity of the at least one first magnet is opposed to the polarity of the at least one second magnet; and (b) the at least one first magnet is movable relative to the at least one second magnet.

Unit for extemporaneous generation of a quantity, variable on request, of a physiological or isotonic solution based on water, including: at least one choice interface for allowing the user to set a desired quantity of solution to be generated from a plurality of possible quantities; at least one water purification station that receives water from outside the unit and to purify it, a manner of supplying (25) at least one solute, at least one mixing station (20) that mixes the purified water with the at least one solute so as to form the desired solution; management system including a calculation system communicating with the interface for calculating the quantity of purified water and the quantity of solute to be mixed for producing the quantity of solution set by the user.
