Scientist Test Giant Sponge to Clean Blue-Green Algae

Scientist have tested a giant specialized sponge to help battle blue-green algae . The sponge was created by AquaFlex Holdings.

It’s called Open Cell foam. It comes in a variety of forms.

This technology has a history of success, for instance, it was used to clean up the BP oil spill in the Gulf of Mexico in April 2010.

The foam acts as a filter in the water and removes bacteria and nutrients. The multinational oil and gas company reclaim spilled oil from the Deepwater Horizon Platform in the Gulf of Mexico with the technology.

The test run took place along the Caloosahatchee River on August 16 and 17. White sponges immediately transformed into a green color as they floated among the blue-green algae, absorbing the toxins for an hour.

The results showed that it absorbed algae and toxins into the foam in concentrations ranging from 45,000 parts per billion to 259,000 parts per billion.

They want to test it further. The goal is to raise $65,000 in funding to perform a pilot study that will test its effectiveness. The money would help them test the technology thoroughly, along with helping devise a long-term plan.

Charlotte Harbor National Estuary Program, AquaFlex Holdings LLC, Sea & Shoreline, Florida Gulf Coast University and the Calusa Waterkeeper are collaborating together on this project.
