In the fight against litter and plastic pollution, ISS Flowthrough bubble barrier technology presents an innovative solution.
How does a Bubble Barrier Stop Litter?
At the heart of our strategy is the implementation of a bubble curtain. The ISS Flowthrough system involves the strategic placement of diffuser heads along a single bore airline. These diffuser heads generate a powerful screen of bubbles, effectively blocking and directing suspended plastics to the water’s surface. The diagonal placement of the bubble curtain guides plastic waste to the side and into a catchment system, ensuring efficient collection and removal.
Why Focus on Rivers?
As much as 80% of the plastic found in our oceans originates from rivers, and research indicates that over 1,000 small to medium-sized rivers are contributing to this alarming problem. Our focus on rivers is strategic—by preventing plastic from reaching the seas, we address the issue at its source. Bubble barrier implementation mitigates the constant flow of plastic from rivers. This makes ISS Flowthrough bubble barriers an instrumental tool in preserving the health of our oceans.


The Urgency of River Litter
Every minute, the equivalent of two rubbish trucks full of plastic reaches our oceans. The most commonly found items in our waterways are plastic bags, bottles, and food containers. Additionally, significant amounts of plastic may be trapped in our rivers, never reaching the seas. It’s a critical concern, considering the adverse impacts of plastic pollution on marine life and human health. The urgency lies in preventing more plastic from making its way into our oceans.
Why Choose Our ISS Flowthrough?
With extensive experience in the bubble barrier business, we bring unmatched expertise. Meticulous research is conducted before installation, ensuring optimal performance.
Our competitors use a weighted perforated hose with a low volume air supple, resulting in a weaker barrier. In contrast, our patented technology employs a single narrow bore airline. This design creates a denser curtain of bubbles, therefore enhancing effectiveness. Learn more about how our bubble barriers differ from other solutions on our main bubble barrier page.
The flexibility of our design adapts seamlessly to diverse environmental challenges. Choosing ISS Flowthrough bubble barriers establishes your area as a leader in combating plastic pollution, marking a step toward cleaner rivers and healthier oceans.
