From wastewater to tap

 Hydrofoss video

Making wastewater pure

Hydrofoss is cleaning wastewater with vacuum evaporation based on a unique patented technology called ScaleGuard®.

Biogas Wastewater

Cleaning wastewater and recyle the treated water in the biogas production. 

Scrubber Sludge

Cleaninging scrubber sludge for reused in the scrubber system.

Industrial Wastewater 

Cleaning all types of industrial contaminated water

Chemical-free cleaning

Hydrofoss is a sustainable choice. All of our solutions come with an integrated ScaleGuard® system that automatically removes scale.

We use neither chemicals or filters.

Low energy consumption

Optimising the energy consumption is a cornerstone of our system. With the
integrated ScaleGuard® system we do not need to continuously flush the system
with cold chemical-filled water.

We can keep the saline water in the system until almost all of it has evaporated and become 
distilled water.

This unique technology has made it possible to improve the energy performance
by 30% compared to the market standard.

Green energy

We can offer our system as either a standalone or as a turnkey solution, including the supply of power. With high energy utilisation, you can power the plant solely with the use of renewable, sustainable and clean energy.

Surplus heat
Surplus heat from engines and factory machinery is an efficient and economic power supply.

Solar panels can be mounted on top of the container, making them easy to transport and install.

For a longterm installation in a windy area, a windmill is a sound solution for power supply. 

Heat generated from biomass of locally grown plants or waste wood.


The combination of a turnkey stand-alone unit, minimum maintenance and low wastewater outlet makes it possible to make clean water almost everywhere.

We can quickly clean unsafe drinking water in disaster areas in for instance refugee camps. Our containerised solution can also clean wastewater from the industry.

Remote monitoring

With our remote monitor system, we can monitor all vital parts of the system from our service office. If a part of the system needs to be checked, we will contact the local staff or crew with service guide instructions. This minimizes downtime and ensures low maintenance costs.


Hydrofoss is not just a green solution, it is also a good investment. The combination of huge savings on chemicals, a cost-saving Smart Service concept and only one annual service required will also save you money from day one.

Circular Economy

Many companies are moving away from the old-fashioned business model of take, make and waste, towards a sustainable circular economy. In short, recycling materials, water and energy, so the world no longer wastes so much stuff. This is the Circular Economy.
