What are canal air curtain weed barriers?
Canal air curtain weed barriers are a system created by Heathland Aquatic Engineering. Air is diffused from the bed of the canal and works its way to the surface where it erupts causing a pushing motion which creates a barrier. Debris drifting up and down canals can become a problem if you own a marina or simply have an area of canal, which is at the end of the line and free flow is not possible. The areas can become choked with rubbish and vegetation that has drifted there, so it's great if you can create a barrier naturally and stop this from occurring.
The design of this system 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 canal or opening to the marina has no effect on the results and the system can be reconfigured to suit any shape, size and depth. All pipe lines are weighted to enable them to be kept out of harms way.
