Wastewater treatment plant construction work
The Ringsend WwTP treats most of the wastewater arising in the Greater Dublin Area. Irish Water is currently planning an upgrade to the Ringsend Treatment Plant based on the application of aerobic granular sludge technology (Nereda®) which will provide for nutrient removal, including Enhanced Biological Phosphorus Removal (EBPR). The introduction of aerobic granular sludge and EBNR will be carried out in phased upgrades of the Ringsend plant, with the aim (inter alia) of reducing the Phosphorus (P) concentration in the wastewater in compliance with relevant legislation. The maximum average capacity of the Upgraded plant will be approximately 2.4 Million Population Equivalent (PE), where 1 PE is taken as 60 g BOD/day.
