  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • SBR Wastewater Treatment Provides Large Clean-up on Small Site

    One of the largest capacity wastewater treatment plants in Europe is under construction on a small plot of land at Ringsend, on Dublin Bay in Ireland. Sequencing batch reactor (SBR) technology and 100,000 diffusers from ITT Industries' Sanitarie unit was selected to meet the challenging waste treatment needs for this site. When Dublin's wastewater treatment plant was built in the 1970s, it ...


  • The development of a Code of Practice for single house on-site wastewater treatment in Ireland

    The performance of six separate percolation areas was intensively monitored to ascertain the attenuation effects of unsaturated subsoils with respect to on-site wastewater effluent: three sites receiving septic tank effluent, the other three sites receiving secondary treated effluent. The development of a biomat across the percolation areas receiving secondary treated effluent was restricted on ...

  • Factors affecting the performance and risks to human health of on-site wastewater treatment systems

    Aerobic wastewater treatment systems (aerobic systems) are the preferred choice in a region overlying a karstic aquifer used for drinking water supplies, as they are thought to provide better protection to groundwater and human health than standard septic systems. However, aerobic systems in operation do not always perform to design standard; while this is often blamed on lack of maintenance, few ...
