Geiger two stage water intake screening system Ras Abu Fontas, Qatar

Ras Abu Fontas A3 desalination plant, Qatar has installed a robust Seawater Screening solution made by the Aqseptence Group Germany.

Challenge

Before seawater is desalinated, it has to be mechanically cleaned of debris in order to protect pumps, condensers and other sensitive downstream equipment from clogging and other damage. Aqseptence Group’s well-proven Geiger® -branded two stage water intake screening system for coarse and fine screening was chosen for this purpose.

Solution

For the first stage in the mechanical screening of seawater (coarse screening), efficient and robust Geiger Cable-Operated Bar Screen with Grab Cleaners were implemented, and for the second (fine screening) the innovative Geiger Centre-Flow Travelling Band Screens.
