The Bubble Barrier

The Bubble Barrier is the first technology to use a bubble curtain to capture plastic pollution in rivers. Over the past 7 years, we have developed the most effective and energy-efficient solution to trap and remove plastic without hindering ship or fish passage.


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:

Bubble curtain

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.

Air supply

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.

Catchment System

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.

How we implement a Bubble Barrier

Before we implement a Bubble Barrier, we carefully conduct research on the preferred location with you to ensure high quality and optimal performance. Typically, we go through the following phases with our clients:


1. Preliminary research

In this phase we assess the suitability of a specific location, the best strategic partners, permit requirements and the indicate the total costs.

2. Realisation

In this phase we will make a final design based on our research and the permit requirements and we will install the Bubble Barrier.

3. Operation

In this phase the Bubble Barrier is fully operational ready to make impact. This includes organizing a launch and executing a tailored communication plan fitted to the local community.

4. Maintenance

The scheduled maintenance of the system can either be done by us or a certified third party.

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:
