Abstract

The performances of a new and a mature
integrated constructed wetland (ICW) system treating
domestic wastewater were evaluated for the first time.
The new ICW in Glaslough (near Monaghan, Ireland)
comprises five wetland cells, and the mature system
in Dunhill (near Waterford, Ireland) comprises four
cells. The performance assessment for these systems
is based on physical and chemical parameters collected
for 1 year in Glaslough and 5 years in Dunhill. The
removal efficiencies for the former system were
relatively good if compared to the international literature:
biochemical oxygen demand (BOD, 99.4%),
chemical oxygen demand (COD, 97.0%), suspended
solids (SS, 99.5%), ammonia nitrogen (99.0%), nitrate
nitrogen (93.5%), and molybdate-reactive phosphorus
(MRP, 99.2%). However, the mature ICW had removal
efficiencies that decreased over time as the Dunhill
village expanded rapidly. Themean removal efficiencies
were as follows: BOD (95.2%), COD (89.1%), SS
(97.2%), ammonia nitrogen (58.2%), nitrate nitrogen
(−11.8%), and MRP (34.0%). The findings indicate
that ICW are efficient in removing BOD, COD, SS,
and ammonia nitrogen from domestic wastewater.
Moreover, both ICW systems did not pollute the
receiving surface waters and the groundwater.
