POWERFUL DOUBLE OXIDATION
BEYOND AOP
THE FUTURE OF MINERALIZATION CHEMISTRY
Today’s complex industrial and landfill wastewaters demand a process that not only oxidizes pollutants but completely mineralizes them — converting every trace of contamination into its simplest, harmless form: CO₂ and H₂O.
SMART PO₂ by Watch Water® Germany is that breakthrough. It is a double-oxidation system that merges two of the most reactive radicals known to chemistry — Hydroxyl (•OH) and Sulfate (SO₄•–) — to create an unprecedented oxidation–reduction potential inside water itself. This process does not require aeration or external oxygen supply.
SMART PO₂ delivers oxygen in its purest, most reactive form — directly where oxidation is needed. As a result, even the most stubborn contaminants, including VOCs, COD, BOD, phenols, humic acids, and sulfides, are dismantled and mineralized in minutes.
APPLICATIONS & ADVANTAGES
SMART PO2
SMART PO₂ has been developed specifically for the toughest water streams where conventional AOPs fail:
Landfill leachate and solid-waste effluent
Chemical, refinery, and textile wastewater
Groundwater and contaminated aquifers
Water reuse and zero-liquid-discharge systems
Its energy-free operation, instant radical formation, and complete mineralization make it a true “Beyond AOP” solution.
No chlorine, no ozone, no aeration, no harmful residues — just oxygen, radicals, and chemistry perfected for the environment.
WHY SMART PO₂
CHANGES EVERYTHING
In traditional oxidation, pollutants are broken into smaller intermediates that still need post-treatment. SMART PO₂ takes the next leap: it pushes oxidation to completion. Every carbon atom is driven to its ultimate destiny – CO₂, every hydrogen to H₂O. This is called mineralization — the cleanest form of purification known.
The process is rapid, self-sustaining, and inherently safe. SMART PO₂ is fully compatible with Watch Water®’s ecosystem of products such as Crystolite®, Katalox-Light®, and Catalytic Carbon®, allowing easy integration into existing plants or containerized systems.

QUESTIONS
What is SMART PO₂?
SMART PO₂ is an advanced double-oxidation system developed by Watch Water® Germany. It combines Hydroxyl (•OH) and Sulfate (SO₄•–) radicals to achieve complete mineralization of pollutants — converting contaminants into harmless CO₂ and H₂O without the need for aeration or external oxygen supply.
How is SMART PO₂ different from traditional oxidation or AOP systems?
Unlike conventional aeration-based or ozone-based oxidation systems, SMART PO₂ doesn’t just break down pollutants into smaller intermediates — it completely mineralizes them. It operates without aeration, consumes no external energy for oxygen supply, and produces no sludge or secondary waste.
What types of contaminants can SMART PO₂ remove?
SMART PO₂ effectively removes a wide range of pollutants, including:
- VOCs (Volatile Organic Compounds)
- COD and BOD loads
- Phenols and humic acids
- Sulfides and other refractory organics
- Metals and phosphates (via precipitation)
How does the double-oxidation process work?
When dissolved in water, SMART PO₂ releases Sulfate radicals (SO₄•–) that react to generate Hydroxyl radicals (•OH). This dual radical chain reaction attacks organic molecules, breaking every carbon and hydrogen bond until the contaminants are fully mineralized into CO₂ and H₂O.
Does SMART PO₂ work with other Watch Water® technologies?
Yes. SMART PO₂ integrates seamlessly with Crystolite® (for microfiltration), Katalox-Light® (for filtration and adsorption), and Catalytic Carbon® (for polishing and final treatment). Together, these create a complete and efficient purification system.
What are the dosing and treatment requirements?
Typical dosing is around 30 g/m³, with a contact time of about 30 minutes. However, actual dosage may vary based on contamination levels, water chemistry, and treatment objectives. Watch Water® provides site-specific guidance for optimized performance.
Is SMART PO₂ safe and environmentally friendly?
Yes. SMART PO₂ contains no chlorine, ozone, or hazardous chemicals. It produces no harmful by-products or toxic sludge — only pure CO₂ and water. The process is inherently safe, sustainable, and environmentally friendly.
