  • On-site industrial wastewater treatment

    Priority pollutant behaviour in on-site treatment systems for industrial wastewaters The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ...

  • Wetlands for Industrial Wastewater Treatment at the Savannah River Site

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial research facility, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. Copper was the ...

  • Site Selection for Food Processing Facilities Wastewater Treatment

    Food processors face an ever changing production schedule which depends largely on the growers products, their finished product customers, labor, and the current market pricing. Many facilities are relocating or looking to relocate to decrease the fixed cost of overhead and labor to try and obtain a competitive advantage over their competitors, which can be only a few cents per pound of finished ...

  • Effectiveness of Alternative On-Site Wastewater Treatment Technologies

    ABSTRACT New York City’s drinking water supply is threatened by the potential development of the Catskill/Delaware watershed. The effectiveness of alternative on-site wastewater treatment systems in this drinking water supply watershed is being evaluated during the course of a oneyear field study. Twenty-four on-site systems were designed and installed for individual sites throughout the ...

  • A simulation of the fate of nitrogen in an on-site wastewater treatment system

    An experiment to study and to build a mathematical model to reproduce the behavior of nitrogen in a residential wastewater treatment process was performed. A pilot unit receiving grey and black water was used. The pilot consisted in a septic tank followed by a fixed-film, partly aerated bioreactor with effluent recirculation operated under two different scenarios: normal operating conditions and ...

  • Long-term hygienic barrier efficiency of a compact on-site wastewater treatment system

    Received for publication September 11, 2008. The long-term use of a filter-based, on-site wastewater treatment system increases nutrient discharge to receiving waters and may reduce its hygienic barrier efficiency. The main purpose of this research was to assess the hygienic barrier efficiency and the associated health risks of an on-site system that had exceeded its 5-yr design capacity with ...

  • Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters

    The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...

  • ON-SITE SEWAGE SYSTEMS: NEW OUTLOOK FOR DECENTRALIZED WASTEWATER TREATMENT

    As researchers analyze the soils’ ability to absorb discharge, more knowledge is gained about alternatives to septic tanks and standard drain fields that include peat filter systems, constructed wetlands and drip irrigation. ONE out of every four American households currently treat and release wastewater on their own property. Although most people assume that on-site systems are confined to rural ...


  • Wetlands For Industrial Wastewater Treatment At The Savannah River Site: A Case Study

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial park-type area, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. However, copper is ...

  • Institutional trajectory for diffusing on-site wastewater treatment in urban China

    Urban water scarcity has been an issue for a long time in China while water pollution has attracted more and more attention over the last two decades. Recently, on-site wastewater treatment (OST) has been proposed as a meaningful alternative to deal with both water pollution and water scarcity in cities in a more sustainable way. However, the diffusion of such an OST system is still slow and ...

  • Effect of alternative on-site wastewater treatment on the viability and culturability of Salmonella choleraesuis

    ABSTRACTThe objective of this study was to determine how alternative on-site wastewater treatment systems (i.e. subsurface flow constructed wetlands, intermittent sand filters and intermittent peat filters) affect the viability and culturability of Salmonella choleraesuis (serotype typhimurium, ATCC 23567). Influent was a high strength septic tank effluent (BOD5 240-344 mg ...

  • 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 ...

  • Decentralized Wastewater Treatment

    An application used worldwide, now growing in US to address the needs of small communities and developments Conventional sewer operations managed by small communities provide centralized treatment of wastewater of which residents are accustomed. But the expense of operating these systems as they expand with miles and miles of sewer lines is staggering. Expanding sewer line infrastructure, ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...
