Reactive filtration offers safety, flexibility and consistency

The alarming degradation of receiving waters in the United Kingdom and Ireland has the environmental agency, together with the municipal water company’s, looking for ways to limit priority substances and other pollutants. While non-point source controls are slowly emerging, point source wastewater dischargers are already feeling the effect of more stringent effluent discharge consents for nutrients (phosphorous and nitrates). There are few technologies available to help treat for priority ...

Case Study: The impacts of Microbial Influenced Corrosion (MIC) in wet sprinkler piping

  Author: David McGreal, senior mechanical engineer, Eli Lilly  Will your wet sprinkler system function correctly in the event of a fire? Does the periodic inspection and regular flow testing through the inspector test valves prove that everything is OK? What is the condition of the inside of the sprinkler piping and what condition is it in? Background [caption id="attachment_26107" align="alignright" width="300"] Fig. 1[/caption] In this particular case study, the ...

Vast energy value in human waste

Biogas from human waste, safely obtained under controlled circumstances using innovative technologies, is a potential fuel source great enough in theory to generate electricity for up to 138 million households -- the number of households in Indonesia, Brazil, and Ethiopia combined. A report from UN University's Canadian-based Institute for Water, Environment and Health estimates that biogas potentially available from human waste worldwide would have a value of up to US$ 9.5 billion in ...

Development of Ireland's largest water treatment plant facilitates future growth for the Dublin region

Author: Grellan McGrath CEng, director RPS From the shore of Blessington reservoir on the Wicklow/Kildare border, the Ballymore Eustace Water Treatment Plant currently supplies an average of 300 million litres per day (MLD) of treated water to consumers in Dublin City, Dun-Laoghaire, south Dublin and part of Kildare. The plant was originally conceived in 1936 under the Liffey Reservoir Act, which facilitated the construction of a 166 million cubic meter impounding reservoir on the ...

Why a water/wastewater industry cluster was established for Ireland

  The water/wastewater industry cluster for Ireland was established in May of 2015 with the facilitation and support of Enterprise Ireland (EI). Approximately 50 attendees were at the establishment meeting of the cluster and these represented SMEs involved in the sector, relevant researchers/third level institutions and other stakeholders, including Irish Water. Why establish a water/wastewater cluster? Ireland has good national capability in the water/wastewater area as a result ...

What 35 years in engineering has taught me

Author: Brian Booth, vice-president, Water Treatment Innovation Platform of global water, energy and maintenance solutions provider, NCH Europe. I've worked in the engineering industry for the last 35 years, starting out as a chemist in the water treatment sector in 1985 One of the biggest changes I've witnessed over the last three decades is the rise of legislation covering every aspect of the industry. It started with basic health and safety and now reaches into countless niche areas, ...
