Water Quality & Treatment
Hydrogen Water Treatment for Irrigation Systems
Hydrogen-rich water treatment as an inline stage in the irrigation train — filtration, pump-inline dosing and water purity for growers and horticulture operators.
In short
Hydrogen-rich water treatment improves dissolved hydrogen stability, oxygenation and irrigation efficiency for growers, greenhouses and CEA operators.
Treatment stage, not a chemical programme
The generator produces dissolved hydrogen from the water passing through it. There is no dosing tank, no consumable reagent and no residual to manage downstream — the treatment ends when the water is used.
Because dissolved hydrogen dissipates at the water surface, treated water is not stored. The system is sized to the irrigation shift so water is hydrogenated immediately before delivery.
How the water is treated
Hydrogen Machines systems dissolve molecular hydrogen into water by PEM/SPE electrolysis at 99.99% hydrogen purity, producing nano-bubbles that stay in suspension longer than coarse aeration. Two capacities cover the range: 3.75 L/min for benches, propagation houses and trial blocks, and 20 L/min for production sites up to roughly ten hectares.
- PEM/SPE electrolysis — no cylinders, no chemical dosing consumables
- Nano-bubble dispersion for longer suspension in the delivery line
- Installed inline after filtration, ahead of the dripline or fertigation manifold
- Hydrogenate close to the point of use; dissolved hydrogen dissipates at the water surface
Compatibility with existing treatment
Hydrogenation is placed after particulate and media filtration to protect the cell, and upstream of fertigation injection. Where reverse osmosis or UV are already installed, hydrogenation follows them as the final stage before distribution.
Nano-bubble hydrogen vs traditional oxygenation
Traditional oxygenation adds air or oxygen by mechanical shear, venturi or diffuser. Electrolytic hydrogenation dissolves molecular hydrogen produced from the water itself, at nano-bubble scale, which stays in suspension longer than coarse bubbles. They are different gases measured by different instruments and are not interchangeable.
Dissolved oxygen irrigation explained
Dissolved oxygen (DO) is a standard irrigation water metric with established meters and targets. Dissolved hydrogen is separate and needs its own meter, reported in ppb. Sites running DO programmes keep them; hydrogenation is logged as an additional parameter, not a replacement.
Hydrogen water for controlled-environment agriculture
In glasshouses, hydroponics and vertical farms the water train is already instrumented, so hydrogenation is added as the final stage before the manifold. Recirculating loops re-treat the solution on each pass instead of storing hydrogenated water.
Inline dosing systems for growers
Inline dosing means the generator is plumbed into the pumped line: source water, filtration, optional RO or UV, hydrogenation, fertigation, distribution. Capacity is matched to the irrigation shift rather than to a storage volume.
Evidence and scope
Published research on hydrogen-rich irrigation water is early-stage and study-specific. We make no yield, disease, plant-health or therapeutic claims. These are general water-treatment systems; evaluate any deployment as a measured trial against your own untreated controls.
Frequently asked questions
- How does hydrogen compare to traditional oxygenation?
- Hydrogen nano-bubbles provide more stable oxygenation and improved water quality compared to traditional dissolved oxygen methods.
- Is hydrogen water treatment a chemical dosing programme?
- No. The hydrogen is produced from the water passing through the cell; there is no reagent, dosing tank or downstream residual.
- Where does it sit relative to RO and UV?
- After them. Hydrogenation is the final treatment stage before distribution, and always downstream of filtration that protects the cell.
- Can treated water be stored in a tank?
- Dissolved hydrogen dissipates at the water surface, so treatment is sized to the delivery shift rather than stored.
- How is performance verified?
- By measuring dissolved hydrogen in ppb at the point of delivery, alongside your existing EC, pH and dissolved-oxygen records.

Nanobubble technology context
Hydrogen Nano-bubble Technology in Irrigation & Water Treatment
Nanobubbles are gas bubbles below roughly 200 nanometres in diameter. Because they are far smaller than the bubbles produced by a conventional aerator or venturi, they do not rise and burst at the surface: they disperse through the water column and stay in suspension for far longer, which is what growers mean by nano-bubble stability, nano-bubble retention and low nano-bubble lift. A nanobubble generator is simply the device that produces that dispersion, usually as inline nano-bubble injection on the pressurised side of a pump.
Most nanobubble equipment in horticulture dissolves oxygen or air, and some water-remediation equipment dissolves ozone. Oxygen and air nanobubbles are used for water oxygenation and root-zone oxygenation — raising dissolved oxygen in irrigation water, hydroponic nutrient solution and aquaculture ponds. Ozone nanobubbles are used for oxidative water remediation and line hygiene. All three are oxidative or neutral gases: they change the oxygen status of the water, and the accepted mechanism is gas transfer, not redox signalling.
Hydrogen nano-bubbles are the advanced modality in the same delivery format. The HERO Irrigation system uses on-site PEM/SPE electrolysis to infuse 99.99%-purity molecular hydrogen as nano-bubbles directly into the irrigation line immediately before the dripper — pump-inline dosing, no chemical inputs, no storage cylinders, and no change to the existing pipework. Molecular hydrogen is a small, neutral, highly diffusive molecule, so nano-bubble dispersion carries it through the emitter and into the root zone rather than releasing it at the surface. Where oxygen nano-bubbles act on the dissolved-oxygen budget, hydrogen acts as a selective reducing species in the water and the root zone — a different mechanism, and the reason hydrogen nano-bubble infusion is treated as the higher-specification option for irrigation, controlled-environment agriculture, turf, nurseries and vineyards. The two are compatible: hydrogen infusion does not displace an existing dissolved-oxygen programme.
Evidence framing, stated plainly. Strongest: the physical chemistry of nano-bubble formation, stability and dispersion, and the measurable hydrogen concentration delivered at the emitter (3,000–5,000 ppb on this system). Moderate: published plant-science work on hydrogen-rich water and root-zone redox behaviour, most of it small-scale or glasshouse-scale. Gaps: long-run, multi-season, crop-specific yield data across soil types and water chemistries is still limited, and site conditions vary. We publish the mechanism and the delivered concentration; we do not publish crop-performance guarantees.
Nanobubble questions
What are nanobubbles in irrigation?
Nanobubbles are gas bubbles smaller than about 200 nanometres suspended in irrigation water. Unlike aeration bubbles they do not rise and burst, so they remain dispersed through the line and pass through drippers and emitters with the water rather than venting at the surface.
How do hydrogen nano-bubbles differ from oxygen nanobubbles?
Oxygen and air nanobubbles raise dissolved oxygen — a gas-transfer effect used for water oxygenation and root-zone oxygenation. Hydrogen nano-bubbles deliver molecular hydrogen, a small neutral molecule that behaves as a selective reducing species in water. The delivery format is the same; the chemistry is not. Hydrogen infusion is complementary to, not a replacement for, a dissolved-oxygen programme.
What is the difference between micro-bubbles and nano-bubbles?
Micro-bubbles are measured in micrometres and still have enough buoyancy to rise and coalesce within minutes. Nano-bubbles are two to three orders of magnitude smaller, have negligible lift, and stay in suspension long enough to travel the length of an irrigation run.
Do nano-bubbles improve water infiltration?
Nano-bubble infusion changes the gas content and interfacial behaviour of the water rather than its bulk viscosity. Infiltration and wetting-front behaviour are reported in field and glasshouse work but depend heavily on soil type, water chemistry and irrigation scheduling, so we describe the mechanism rather than promising an infiltration figure.
Are nano-bubbles used in CEA and hydroponics?
Yes. Controlled-environment agriculture, hydroponics and vertical farming are the most common settings for nanobubble equipment, because the nutrient solution is recirculated and closely monitored. Hydrogen nano-bubble infusion is applied the same way: inline, on the pressurised side of the pump, ahead of the distribution manifold.
How stable are hydrogen nano-bubbles?
Nano-bubble stability is a function of size distribution and surface charge, not of the gas alone. Because the system infuses immediately before the emitter, retention time between injection and delivery is short by design, which is why the delivered concentration at the dripper (3,000–5,000 ppb) is the figure we specify rather than a shelf-life claim.
Can nano-bubbles be used in turf management?
Turf and golf irrigation is a standard nanobubble application, typically through the existing pressurised distribution system. Hydrogen nano-bubble injection integrates the same way, inline at the pump house, without changing sprinkler or valve hardware.
What is inline nano-bubble injection?
Inline nano-bubble injection means the generator sits within the irrigation line itself and infuses gas into the flowing water under pressure, rather than treating water in a holding tank. It is also described as pump-inline dosing, and it keeps the treated water travelling straight to the emitters.
How do nano-bubbles support root-zone conditions?
Because nano-bubbles remain dispersed rather than venting, gas reaches the root zone with the irrigation water instead of being lost in the line. Oxygen nano-bubbles act on root-zone oxygenation; hydrogen nano-bubbles introduce a reducing species into the same zone. Both are mechanisms of delivery — site response depends on crop, substrate and water chemistry.
Can nano-bubble systems be used for irrigation water treatment and remediation?
Nanobubble equipment is widely used in irrigation water treatment, aquaculture oxygenation and water remediation. The HERO Irrigation system is a hydrogen infusion device: it adds molecular hydrogen to the water and does not disinfect, filter or replace an existing water-treatment or filtration stage.
