The Great Bubble Barrier
Bubbles to filter river water
The bubble barrier traps plastic across the width and depth of rivers and prevents plastic from ending up in the ocean. The system does not interfere with regular river activities and is operational 24/7.
The Great Bubble Barrier creates a curtain of bubbles by pumping air through a perforated tube at the bottom of the waterway. The bubble curtain creates an updraft that directs the plastic to the surface. By placing the bubble barrier diagonally across the river, the natural flow of water pushes the plastic waste to the side and into the collection system.
The capture system is designed to work in harmony with the bubble curtain to collect and retain plastics. Once collected, they will be removed for processing and reuse.
