The Bubble Barrier
Over the past 5 years, we have developed the best and most energy-efficient solution for using bubbles to trap and remove plastics from waterways.

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 plastic to the surface. By placing the Bubble Barrier diagonally across the river, the natural flow of the water will push the plastic waste to the side and into the catchment system.
The catchment system is designed to work in harmony with the bubble curtain to collect and retain plastics. Following collection, it will be removed for processing and reuse.
The Bubble Barrier system
The Bubble Barrier comprises three main components: the bubble curtain, the compressor, and the catchment system. The three components are designed to work together to create the optimum solution for each location. The components are:
The location and necessary airflow of our bubble curtain are adapted according to the flow dynamics of the river or waterway. The bubble hose is made from rubber tubing and is ideally suited to application in a wide range of locations.
The bubble curtain is created by using compressed ambient air. We use electric compressors that are optimised for the bubble curtain and tailored to the requirements of continuous operation and to any location-specific characteristics. Wherever possible, we aim to power our Bubble Barrier with renewable energy. This may vary per city and infrastructure.
The bubble curtain will be paired with the most suitable catchment system. We have developed our own catchment system which can be adapted to the local infrastructure at the site, for example, to accommodate how it will be emptied by local authorities.
Bubble Barrier Benefits
Safe for fish passage
Migrating fish can pass through the bubble curtain or through the system’s fish passage.
The bubble curtain extends across the full width and depth of the waterway.
Our system is suitable for a wide range of locations, without requiring changes to existing local infrastructure.
Increases dissolved oxygen
Bubble curtains increase the dissolved oxygen at the site, benefitting the aquatic ecosystem.
No operators are needed to ensure the system functions round the clock, while monitoring can be handled remotely.
Open for ship traffic
Ships can navigate the Bubble Barrier without obstruction.

Which rivers are suitable?
Every river is unique. Therefore, we carefully assess the options for installing a Bubble Barrier in each instance. A Bubble Barrier is suitable for many different sizes and types of rivers, as follows:
River type A
A canal which is mainly used for recreational and smaller tourist boats. This type is typically around 30 m wide and is often no more than 2m deep. The canal may flow in various directions.
River type B
A canal with a constant discharge and flow in one direction only. Typically, this type varies in depth between 2m to 5m and in width between 30 m up to 50 m. Ship traffic is predominantly recreational, with some occasional commercial ship traffic. The profile of the river is broadly rectangular and often man-made.
River type C
A river that has been significantly shaped by human activity; it has been mostly straightened with few, if any, meanders remaining. It is predominantly used for commercial ship traffic, including bulkers, tankers and container and river cruise ships. The deepest parts may be 5-7m, while widths vary from 100m up to 200m. Typically, there is a constant downstream flow with seasonal fluctuations in discharge.
This type typically ranges from 30m up to 200m in width, but with tidal influence. Therefore, there are constant changes in the direction of flow. Depending on the nature of the river, it could be home to both recreational and commercial ship traffic.
