Advanced oxidation and on-site hydrogen peroxide generation
Hydrogen peroxide made on site from water, air and electricity. No deliveries, no bulk storage, no handling exposure — and an oxidant strong enough for trace organics.
The starting point
What problem does it solve?
- “Chemical deliveries to this site are a nightmare”
- “Chlorine is corroding our cooling system”
- “We have trace organics we cannot get below the limit”
- “Hydrogen sulphide odour is generating complaints”
- “Biofilm keeps coming back in the closed loop”
Your solution can be on-site H₂O₂ and AOP.
Glorinda, in partnership with HPNow, provides sustainable hydrogen peroxide-based solutions for clean water and sanitation in municipal and industrial applications. The GOgen® technology produces high-purity hydrogen peroxide directly from water, air and electricity — it is safe, efficient and designed for decentralised use.
That changes the economics of oxidation. Most sites do not avoid advanced oxidation because it does not work; they avoid it because bulk peroxide means deliveries, storage, permits, handling procedures and a safety case. Generating it on demand removes all of those, and the system is fully autonomous with no chemical inputs.
Why it pays
Benefits
No chemical logistics
Reduced chemical usage, lower logistical and handling costs, and improved supply reliability and occupational safety. Eliminates transport, storage and safety risks entirely.
Fully autonomous
A fully autonomous system with no chemical inputs. It starts with water and ends with water — the membrane-based electrolyte design removes the need for handling liquid chemicals or gaseous hydrogen.
Modular and scalable
The system is modular and scalable, with cells that can be stacked to meet different capacity needs — so a pilot duty and a full plant duty use the same technology.
Chlorine-free chemistry
Replaces corrosive chlorine, reduces corrosivity and improves cooling efficiency while extending system lifespan. No corrosion, salinity or toxic byproducts.
Real oxidation power
UV-activated hydrogen peroxide removes trace organic contaminants — pharmaceuticals, cosmetics, pesticides — with zero chemical residues and enhanced discharge compliance.
Lower footprint
Also reduces the carbon footprint and overall environmental impact of water treatment, and it is compatible with renewable power for zero-emission oxidation.
Process
How it works
The technology produces high-purity hydrogen peroxide directly from water, air and electricity. Oxygen from air is reduced electrochemically in the presence of water; the membrane-based electrolyte design means the solution is generated without the need for gaseous hydrogen or water vapour, and without handling liquid chemicals.
Downstream, the peroxide is dosed into the duty it serves. For advanced oxidation, UV activation generates hydroxyl radicals that attack organic contaminants conventional treatment leaves behind.

Generation
Direct electrochemical production of hydrogen peroxide from water, air and electricity. Safe, efficient and designed for decentralised use, with stackable cells for different capacities.
Storage and dosing
The generated peroxide is held in a reservoir and dosed by pump into the line being treated. Because generation is continuous and on demand, the reservoir is small compared with a bulk chemical installation.
Oxidation duty
Depending on the application: direct oxidation of contaminants, UV-activated advanced oxidation for trace organics, biofilm control in closed loops, or hydrogen sulphide neutralisation for odour control.
| Sector | Duty | What it does |
|---|---|---|
| Industrial | Cooling water treatment | Prevents biofilm buildup in closed-loop systems; replaces corrosive chlorine, reduces corrosivity and improves cooling efficiency while extending system lifespan; reduces water and energy consumption |
| Industrial | Effluent treatment | Replaces bulk hydrogen peroxide with safe onsite generation; eliminates transport, storage and safety risks; high-efficiency oxidation with zero chemical residues; enhances discharge compliance |
| Industrial | Advanced oxidation (AOP) | Removes trace organic contaminants such as pharmaceuticals and cosmetics; UV-activated hydrogen peroxide; chemical-free, safe and regulation-friendly |
| Industrial | Odour control (H₂S) | Neutralises hydrogen sulfide in wastewater; prevents infrastructure corrosion and health hazards; eco-friendly alternative to traditional oxidants |
| Municipal | Drinking water | Targets tough pollutants including pharmaceuticals and pesticides; eco-friendly onsite generation; leaves no harmful residues |
| Municipal | AOP and odour control | Removes trace organic compounds (TrOCs); chemical-free, cost-saving AOP; neutralises odours without harmful chemicals; continuous, automated treatment |
| Agriculture | Irrigation systems | Prevents clogging and ensures even water distribution; boosts oxygen levels naturally; EU/US organic certified with no harmful residues; extends irrigation system lifespan |
| Food & beverage | Process and packaging water | Eliminates waterborne hazards without harmful residues; no taste, odour or harmful by-products; preserves taste and quality; meets strict safety standards |

Engineering support for this technology
Selecting a process is an engineering decision, not a purchasing one. We run feasibility and pre-feasibility studies, characterise the stream, compare the routes on capital and operating cost, and act as owner's engineer while somebody else builds it if that suits you better.

FAQ
Questions engineers ask
Taken from the questions procurement teams, plant managers and consultants actually send us.
How is the hydrogen peroxide produced?
Directly from water, air and electricity, by electrochemical reduction of oxygen. The membrane-based electrolyte design means the solution is generated without gaseous hydrogen or water vapour and without handling liquid chemicals.
What capacity is available?
The system is modular and scalable — cells stack to meet different capacity needs, so the same technology covers a small municipal duty and a large industrial one. Tell us the dose rate and flow and we will size it.
Is it really cheaper than buying peroxide?
It depends on your site. The direct chemical price is only part of it: the comparison also has to include delivery, storage, permits, handling procedures, dilution losses and the safety case. On remote sites, and on sites where chemical storage is constrained, on-site generation usually wins comfortably.
Can it replace chlorine in our cooling system?
That is one of its main duties. It prevents biofilm buildup in closed-loop systems, replaces corrosive chlorine, reduces corrosivity and improves cooling efficiency while extending system lifespan — with no salinity or pH change.
Who is the technology partner?
