River Air Curtain Weed Barriers

 Debris drifting up and down Rivers can become an issue if you own a marina or simply have an area of river which is cut off with very little flow. This causes these areas to choke with rubbish, vegetation thats drifting and in many cases these areas become choked with Duckweed.

What is a River Air Curtain Weed Barrier?

River Air Curtain Weed Barriers are a system created by Heathland Aquatic Engineering, where 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 Aquatic Engineering and we are able to supply this solution around the world. We have also seen good results in salt water environments and have used the system to keep seaweed out of marinas, again this has worked to good effect.

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 pipe lines are weighted to enable them to be kept out of harms way.
