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.
