Our technology

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.

The concept

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 Product

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:

    Bubble curtain

    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.

    Air supply

    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.

    Catchment System

    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.
