Research 255: Optimal design and operation of small-scale wastewater treatment plants: the Irish case

Authors: Lorna Fitzsimons, Greg McNamara, Edelle Doherty and Eoghan Clifford, August 2018

Year: 2018

There are many variables which must be considered when designing and operating a wastewater treatment system. The key objectives of this research were to develop software tools to assist in the selection and management of wastewater treatment systems, with a specific focus on small wastewater treatment plants in Ireland.

Research 249: Catchment Management Support Tools for Characterisation and Evaluation of Programme of Measures

Authors: Eva M. Mockler and Michael Bruen, May 2018

Year: 2018

Nutrient enrichment and eutrophication can negatively impact on freshwater ecosystems, estuarine and coastal waters. As a result of improvements in nutrient management and regulation, there has been a large reduction in total phosphorus, total ammonia and total nitrogen emissions from Irish catchments in recent decades.

Research 240: Technologies for Monitoring, Detecting and Treating Overflows from Urban Wastewater Networks

Authors: David Morgan, Liwen Xiao and Aonghus McNabola, March 2018

Year: 2018

In Ireland, most urban areas are drained by combined sewer systems, which convey wastewater and stormwater in a single pipe. During rainfall the capacity of combined sewers may be exceeded, leading to untreated discharges to receiving waters via storm water overflows (SWOs), which are a source of microbial pathogens.

Research 234 - One-step Drinking Water Treatment Using Filtration and Nanostructured Composites

Authors: Anne Morrissey, Declan McGlade, Kieran Nolan, Brid Quilty and Jenny Lawler, December 2017

Year: 2017

This report provides a summary of the findings of the research on the design, development and testing of a novel drinking water treatment system using a combination of filtration and nanostructured composites for the removal of inorganic, organic and microbiological contaminants from water.

Research 231: Assessment of Natural Organic Matter (NOM) and Ptaquiloside in Irish Waters

Authors: Connie O’Driscoll, Liwen Xiao, Xinmin Zhan, Bruce Misstear and Francesco Pilla, November 2017

Year: 2017

Ireland has an unacceptably high number of drinking water supplies that exceed the parametric value of 100 μg L-1 for total trihalomethanes (THMs) and has been reporting the highest non-compliance with respect to total THMs in drinking water across the 27 EU Member States.

Authors: Michael Bruen, Anna Rymszewicz, John O’Sullivan, Jonathan Turner, Damian Lawler, Elizabeth Conroy and Mary Kelly-Quinn, November 2017

Year: 2017

The SILTFLUX project addressed three major objectives related to sediment pollution in rivers.

Research 229: Developing the Concept of Catchment Services for Progress Towards Integrated Water Management (Extra TIMe)

Authors: Alec Rolston, Eleanor Jennings, Suzanne Linnane and David Getty, November 2017

Year: 2017

The benefits and disservices received by people and ecosystems within catchments are called catchment services and disservices. Their delivery can be influenced by multiple factors including climate, legislative/policy and social (demographic) change.
