Weed curtains or barriers for rivers, canals, lakes and marinas
Debris drifting up and down rivers can become an issue, especially if your marina or an area of the river is cut off with very little water flow. These areas can become choked with rubbish and vegetation that’s drifting and, in many cases, they become choked with duckweed too. Weed curtains or a weed barrier can prevent this.
What are weed curtains or a weed barrier in a river?
River air curtain weed barriers are a system created by Heathland Group. Air is diffused from the bed of the river and travels to the surface, where it erupts causing a spreading motion.
This system design is unique to Heathland Group and we are able to supply this solution around the world. We have also seen good results in saltwater environments and have used the system to keep seaweed out of marinas and it seems to be quite effective.
The width of the river or opening to the marina has no effect on the results and the system can be reconfigured to any specifications required. All pipelines are weighted to keep them out of harm’s way.
