The Bubble Barrier
Over the past 5 years, we have developed the optimal and most energy-efficient configuration for using bubbles to collect and remove plastics from waterways.
Contact us to discover the possibilities to place a Bubble Barrier in your river.
How does the Bubble Barrier work?
We create a bubble curtain by pumping air through a perforated tube on the bottom of the waterway. The bubble curtain creates an upward current which directs the plastics to the surface. By placing the Bubble Barrier diagonally in the river, the natural flow will push the plastic waste to the side and into the catchment system.
The design of the catchment system works in harmony with the bubble curtain to collect and retain plastics. From here it will be removed from the water for processing.
The Bubble Barrier system
The Bubble Barrier comprises of three main components: the bubble curtain, the compressor, and the catchment system. The three components are designed to work together to create an optimal solution at each location. The components outlined:
The placement and required airflow of our bubble curtain are decided according to the location’s flow dynamics. The Bubble Tubing® is made out of PVC rubber tubing and is optimally suited to be applied in a wide range of locations.
The bubble curtain is created by using compressed ambient air. We use electric compressors that are tailored to the bubble curtain’s requirements, continuous operation, and location-specific characteristics. Wherever possible, we try to power our Bubble Barrier with renewable energy. This may vary per city and infrastructure.
The bubble curtain will be matched with the best suitable catchment system. We have developed our own catchment system which can be adapted to the location’s infrastructure, such as to accommodate the method of emptying by local authorities.

Which rivers are suitable?
Every river is unique. Therefore, for each case, we carefully assess the possibilities of implementing a Bubble Barrier. Below you will find a simplification of the types of rivers that are suitable.
River type B
A canal with a constant discharge and therefore one flow direction. Typically, this type has depths varying between 2m to 5m and a width varying from 30 m up to 50 m. Ship traffic is predominantly recreational and occasionally commercial ship traffic. Cross-section of the river is mainly rectangular and often man-made.
River type C
A river that has been strongly influenced by human activity and is therefore mostly straightened and not meandering. It is used predominantly for commercial ship traffic, including bulkers, tankers, container and river cruise ships. The deepest parts may be 5-7m, width varies from around 100m up to 200m. Typically, there is a constant downstream flow direction with seasonal changes in discharge.
