What we do

We clean all types of chemical- and biologically contaminated water. The clean distilled water can be reused in the production. Making it an evironmental friendly and cost-saving solution.

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

How we do it

At Hydrofoss we clean wastewater by vacuum evaporation. We use a heat exhanger to boil the wastewater. The chemicals can not follow the steam witch seperates the destilled water from the contaminated water.

This process reducess the wastewater by more than 95%.


All of our solutions come with our unique cleaning system called ScaleGuard®. It is automatically activated for two minutes every hour. Securing that the system is always clean - no matter how aggressive the wastewater is.

We use no chemicals and no filters.

Low energy consumption

This allows us to keep the hot saline water in the system until it has evaporated. Improving energy performance by 30% compared to the market.

Standard systems must continuously flush their evaporator plates with cold chemical-filled water. To compensate, more heat is needed to keep the water at boiling point. This requires energy and the excessive flushing gives more wastewater.


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

From beginning to end no chemicals are added.

Compact & durable design

A Hydrofoss unit has a compact design. We only need the footprint of a euro pallet.

We have no moving parts that can wear. We use a materials of the highest quality, designed to withstand even the toughest chemicals.

Remote monitoring

With our remote monitor system, you can monitor all vital parts of the system from the bridge og office. The system is operated by a PLC wich also logges and save all sensor data.


Hydrofoss is not just a green solution, it is also a good investment. The combination of huge savings on chemicals and filters, no maintenance cost and only one annual service required will also save you money from day one.
