  • Using submersible fluorescence sensors to track the removal of organic matter in decentralized wastewater treatment systems (DEWATS) in real time

    Decentralized wastewater treatment systems (DEWATS) using anaerobic treatment are increasingly being considered for wastewater treatment with options for non-potable water reuse at the community scale. One challenge for ensuring performance and reliability of DEWATS is the lack of suitable on-site sensors to monitor failure or contamination events. In this study, the aim was to use in situ ...

  • Estimation of the dilution field near a marine outfall by using effluent turbidity as an environmental tracer and comparison with dye tracer data

    The alternative use of effluent turbidity to determine the dilution field of a domestic marine outfall located off the city of Rio de Janeiro was evaluated through field work comprising fluorescent dye tracer injection and tracking with simultaneous monitoring of sea water turbidity. A preliminary laboratory assessment was carried out with a sample of the outfall effluent whose turbidity was ...

  • Assessment of field fluorometers

    Two field fluorometers, devoted either to natural organic matter (NOM) or to tryptophan-like fluorescing substances, were tested for the characterization of a large set of water samples (n = 263) impacted to various degrees by untreated or poorly treated urban sewage. Both fluorometers yielded consistent results when testing discrete samples. A nonlinear correlation (coefficient of ...

  • SMF4 case study 3

    Bathing Water Catchment monitoring Date:2010 Location: Bude Cornwall UK Purpose: To carry out a river survey identifying potential pollution sources and their likely impact on bathing waters downstream. Background STS and the Environment Agency have, for some time, been discussing the issue of monitoring water courses which ...

  • SMF4 case study 2

    Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. Background STS was invited independently by the Environment Agency and Severn ...

  • SMF4 case study 1

    Recycled water plant monitoring Date: 2011 Location: New South Wales Australia Purpose: To determine if the SMF4 could be used to monitor the output from a grey water recycling plant and conclusively differentiate the output water between potable and recycled. Background STS has had a long history of closely working with ...

  • ANDalyze Case Study - Uranium in Ground Water

    Good Water Company (Testing Service) Groundwater samples were submitted by well owners from different regions of New Mexico (around Espanola region) in a water clinic sponsored by the Good Water Company. Problem/Task The groundwater in this region is contaminated with natural uranium, often above the EPA maximum contaminant level of 30 ppb uranium. ...

  • Mining Water Quality Application

    Isaac Plains Coal Mine Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). One of the environmental monitoring requirements which must be met is monitoring water. These include potable water, mine affected water, natural creek flows, water releases, groundwater and the receiving environment. The ...

  • Rapid quantification of polyhydroxyalkanoates (PHA) concentration in activated sludge with the fluorescent dye Nile blue A

    The present study was conducted (1) to develop a rapid quantification method of polyhydroxyalkanoates (PHA) concentration in activated sludge by Nile blue A staining and fluorescence measurement and (2) to perform on-line monitoring of PHA concentrations in activated sludge. Activated sludge samples collected from laboratory scale sequencing batch reactors and full-scale wastewater treatment ...

  • Simultaneous Nitrification and Denitrification through Low-DO Operation

    Single-tank simultaneous nitrification and denitrification (SNdN) processes can potentially eliminate the need for separate tanks and for recycling mixed liquor from oxic nitrifying zones to the typically upstream anoxic zones for denitrification. However, the conditions involved are more susceptible to sludge bulking by excessive growth of filamentous bacteria. This study was aimed at ...
