New way to fight off blue-green algae

The local environment protection department implemented machines to pump the algae from the lake to a treatment reservoir where it would be decontaminated and recycled, which was the latest solution to fight off blue-green algae on the Chaohu Lake. The new method is able to deal with almost a thousand tonnes of blue-green algae every day, according to local media. [Photo/Agencies]
