SCWO systems for purifying the toughest wastewater

Waterox - a green and efficient turnkey solution

Aquarden’s prize-winning and patented SCWO technology, Waterox, completely eliminates hardly-degradable organics and toxic matter in your wastewater. We know this because we have tested and treated many wastewater types and the results speak for themselves.

Regardless of whether the wastewater consists of landfill leachate, biologically hardly-degradable detergents, solvents from chemical industry, phenolic wastewater, or substances derived from pharmaceutical production, our Waterox technology removes all organic pollutants. At the same time it can reuse energy and water.

Outstanding performance and lower costs

SCWO is short for SuperCritical Water Oxidation. We use the proven purification properties of SCWO to resolve tough wastewater challenges across a variety of industries. SCWO is the cost-effective method for eliminating all organic compounds and other toxic wastewater components. Learn more about the SCWO method.

Flexible setup

The Waterox systems are installed onsite at our clients’ premises right at the source of pollution, or at local cleaning stations.

We charge a competitive fee per treated cubic meter of wastewater. In this way companies can focus on their core businesses instead of having to worry about – or invest in – wastewater treatment systems. And we can focus on our core competence: helping our customers in optimizing their wastewater treatment.
