The Bubble Barrier prevents plastic pollution by creating a bubble screen within the waterway. This is achieved by placing the tube (with holes) along the bottom of the waterway and pumping air through a tube.
The amount of money needed for full implementation of a new Bubble Barrier highly depends on the local conditions (width, depth, flow velocity, etc). Correspondence with the Manufacturer in August 2020
Intellectural Property Type
User Provision Model
Users can obtain the product by directly contacting the manufacturer.
Distributions to Date Status
As of August 2020, Bubble Barriers have been installed at a wastewater treatment plant in Wervershoof, New Holland and in Amsterdam, commissioned by the Regional Water Authority Amstel, Gooi and Vecht and the municipality of Amsterdam
Power supply type

The manufacturer can be contacted regarding the replacement of any components such as the PVC tube or compressor.
Manufacturer Specified Performance Parameters
The manufactured specified performance targets are as follows:
- Animal-friendly: The Bubble Barrier forms a barrier for plastics, but allows fish to pass
- Ship-friendly: The Bubble Barrier has no effect on passing ships
- Full Range: The Bubble Barrier reaches entire width and depth of a river or canal
Vetted Performance Status
Initial concept testing took place in the flumes at Deltares in May 2017. A 200 m length Bubbles Barrier was subsequently tested at Kampen in the IJssel at the end of 2017. The 3-week investigation shows that that the Bubble Barrier works under all Dutch autumn weather conditions and that it catches 86% of all used test material on average.
No known safety hazards are related to this product. However, the manufacturer must be involved in its correct installation in a waterway.
Complementary Technical Systems
The manufacturer indicated they are always looking for creative uses for the plastic which has been removed, in order to create more awareness about waterway pollution.

Compliance with regulations
It is understood that the Bubble Barrier is compliant with known regulations as the product does not require any changes in infrastructure or policies. Any potential issues arising from implementation in different countries will be addressed on a project basis with the relevant authorities.
The manufacturer cites laboratory testing to assess the product’s ability to block all types of materials under all weather conditions present during a Dutch November month catching 86% of all used test material on average.
