Geiger® Cable-Operated Bar Screen & Geiger MultiDisc®

Dublin Waste to Energy Plant installed Innovative Seawater Screening Equipment as ideal solution to their mechanical seawater cleaning requirements.

Challenge

The Dublin Waste to Energy plant is the Irish capital’s first such facility and treats up to 600,000 tons of waste annually, providing electricity for 80,000 homes and district heating for upwards of 50,000 homes. Before using seawater as a cooling medium, 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 Geiger®-branded two stage water intake screening system was chosen for this purpose.

Solution

For the first stage in the mechanical screening of seawater (coarse screening), the efficient and robust Geiger® Cable-Operated Bar Screens with Grab-Cleaner were implemented, and for the second (fine screening) the innovative, compact and low-maintenance Geiger MultiDisc®
