NOAH replaces conventional biological wastewater treatment with a compact electrochemical process that is faster, cleaner, and easier to integrate. Even under variable and intermittent operating conditions. Our patented technology treats wastewater directly at the source, without chemicals, without complex biological reactors, and without greenhouse gas emissions.
Closing the water loop with electrochemistry
A new generation of wastewater treatment
Traditional wastewater treatment depends on biological processes that require large tanks, continuous monitoring and stable operating conditions. These systems are sensitive to load fluctuations, temperature variation and toxic shock. They don't allow intermittent use. They generate greenhouse gasses. They fail to remove phosphorous, micropollutants and bacteria.
NOAH uses electrochemistry instead.
By applying a controlled electrical current, contaminants are removed almost instantly without relying on bacteria or chemical additives. The result is a treatment process that is compact, efficient and predictable.
Benefits
- Instant operation
- Handles variable and intermittent loads
- No biological processes
- No added chemicals

The patented Tube-in-Tube Reactor
Designed for performance. Built to scale.
At the heart of every NOAH installation is the patented Tube-in-Tube reactor.
Unlike conventional plate reactors, the concentric Tube-in-Tube design creates a uniform electric field across the entire flow path. Wastewater flows continuously through the reactor while contaminants are removed through electrocoagulation.
The result is a reactor that delivers consistent treatment performance while preventing clogging—a major limitation of conventional electrochemical systems.
Because the reactor is compact and modular, manufacturers can integrate it directly into their own products without redesigning their complete system.
From wastewater to reusable water in five steps
1. Influent
Pretreatment and homogeneization of incoming wastewater.
2. Electrocoagulation
An electrical current destabilizes dissolved contaminants, heavy metals and suspended particles, causing them to bind together into removable flocs.
3. Dewatering
Separation and filtration of clear water and sludge.
4. Electro-oxidation
Disinfection & micropollutant removal.
5. Reclaimed Water
Clean water becomes available for reuse or safe discharge, helping close the local water cycle.
