removal of invasive plants

We are able to collect from the water up to half a millimeter-sized particles, and our vessel can collect as much as 200 cubic meters of biomass per hour.

There are plenty of nutrients in the water as a result of industrial, wastewater and food production.

As a result, the waterways become eutrophic, which leads to their deterioration, changes in the communities of organisms and the loss of oxygen in the bottom.

In the eutrophic waters beaches and shoals grow out, which makes it difficult to swim in waterways. The mud layers of the bottoms thicken, causing the bacteria that break them to consume more and more oxygen. The subsequent loss of oxygen kills fish and other aquatic organisms.

We can do better. Already today.

The water cleaning vessel developed and manufactured by Clewat is capable of removing algae and other harmful vegetation from the water.

Our solution is a catamaran raft which, with the booms in front, collects plants at the mouth of the vessel, where the water flow is regulated so, that various plants and impurities end up on the vessel’s conveyor and further sorted into trash. 

Flow-based technology does not cause mechanical stress on water bodies and the operation has no negative environmental impact. 


It is possible to collect more than 200 cubic meters harmful vegetation per hour on a single vessel and by adjusting the length of the booms, the width of the area to be treated can be increased even over a kilometer.
