se-quagga-mussels-screen-key-visual

Zebra and quagga mussel resistant water intake screens

Known for blocking water intake systems, zebra and quagga mussels increase maintenance costs and disrupt water treatment. Their high reproductive rate worsens these issues, while their plankton consumption harms native species and degrades water quality. To overcome this challenge, ANDRITZ teamed up with scientists to research the habitat and reproductive behavior of quagga mussels and developed a blockage-free water intake solution.

How can a screening technology help harvest the power of the sea?

Did you know: Our AquaScreen headworks screen helps protect one marine geothermal power plant’s valuable equipment from debris, providing corrosion-proof protection for decades of exposure to high-salinity Mediterranean seawater.
