  • Final effluent monitors protect wastewater treatment efficiency

    Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...


  • Dairy Effluent Treatment - Total Phosphorus Monitoring

    Dairy Crest's Davidstow site operates a sophisticated effluent treatment plant to ensure that the local aquatic environment is protected. The treatment plant has been upgraded to keep pace with the expansion of the factory and a number of our monitoring instruments have been employed to make the operation of the plant as efficient as possible. During 2011, the Environment Agency approached Dairy ...

  • Biological Monitoring Tools for Recycling Hazardous Effluents

     Abstract Increasing dependence on chemicals and rapid developments in chemical technology have practically triggered the growth of chemical industries in India. Globally, Basel convention guidelines are available for transboundary movement of hazardous wastes. However, at the national levels, health damage, resources losses and ecological impairment due to hazardous wastes indiscriminate ...


  • Whole Effluent Toxicity Testing

    What is Whole Effluent Toxicity (WET) testing? Whole Effluent Toxicity (WET) testing is an important component of the U.S. Environmental Protection Agency’s (USEPA’s) integrated approach for detecting and addressing toxicity in surface waters. The National Pollutant Discharge  Elimination System (NPDES) permit program, authorized by the Clean Water Act, controls water pollution by ...

  • Treatment plant protected by effluent monitor at major drinks factory

    The installation of a BioTector continuous TOC (Total Organic Carbon) monitor to police the front end of Cobevco’s wastewater treatment plant has enabled tight control of the treatment process. Delivering results 20 times faster than laboratory techniques, the monitor at the Elton facility in Cheshire provides advance notice of organic overload so that the plant is able to instantly divert ...


  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...


  • Reducing Effects Of Endocrine Disrupting Compounds: Effluent Blending

    Treatment of Publicly Owned Treatment Works (POTW) sewage effluents to minimize adverse impacts to the environment has rapidly progressed through time. However, the increasing population and industrial demand for increased treatment combined with the developing interest in endocrine disrupting compounds (EDCs) in receiving waters are becoming a critical environmental concern. EDC levels in ...

  • Biofuels effluent, does it exceed regulatory limits?

    The US Environmental Protection Agency (EPA), as well as other regulatory agencies around the world, have established limitation guidelines for discharges of “oily wastes” from facilities utilizing any type of oil and grease in their manufacturing process. However, recently several biodiesel plants in the US have been fined for illegally discharging vegetable-based oil and grease and polluting ...

  • Development and implementation of indices for the quality of treated effluent

    The developed monitoring and evaluation system is based on 113 chemical, ecotoxicological and microbiological/virological parameters and consists of two complimentary schemes: a) the traditional one, which provides technical or legal oriented information and is based on the independent evaluation of each parameter against legal limits, and b) the amoeba-effluent yardstick which provides ...

  • Evaluation of polishing of the effluent from UASB reactor by diffusers

    Effluents from bench scale 56 L upflow anaerobic sludge blanket (UASB) reactor and four UASB based sewage treatment plants (STPs) of capacities ranging from 27 ML/d to 70 ML/d were aerated in batch as well as in continuous mode of operation. The process was monitored by measuring temporal trend in Oxidation Reduction Potential (ORP), dissolved oxygen (DO), chemical oxygen demand (COD) and ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Secondary Effluent Depth Filtration Medium Capacity

    ABSTRACTThe filter medium has a maximum accumulation capacity for the particulate material removed from the suspension that is being filtered. The maximum accumulation capacity (generally referred to as maximum specific deposit [MSD]) of the filter is basically an equilibrium condition, when the binding strength between the particles and the collecting medium (collecting medium can be the medium ...

  • Root length of aquatic plant, Lemna minor L., as an optimal toxicity endpoint for bio‐monitoring of mining effluents

    Lemna minor, a free‐floating macrophyte, is used for bio‐monitoring of mine effluent quality under the Metal Mining Effluent Regulations (MMER) of the Environmental Effects Monitoring (EEM) program in Canada, and is known to be sensitive to trace metals commonly discharged in mine effluents such as nickel. Environment Canada's standard toxicity testing protocol recommends frond count (FC) and ...

  • Monitoring endocrine activity in kraft mill effluent treated by aerobic moving bed bioreactor system

    A Moving Bed Bioreactor (MBBR) was operated at three different hydraulic retention times for a period of 414 days. The fate of the extractive compounds and the estrogenic activity of the Pinus radiata kraft mill effluents were evaluated using Yeast Estrogen Screen (YES) and gas chromatography – mass spectrometry (GC-MS) detection. Results show that the MBBR reactor is able to remove between ...

  • Membrane filtration of municipal wastewater effluents for implementing agricultural reuse in southern Italy

    Membrane filtration was investigated at field scale in order to assess its effectiveness for reusing municipal effluents in agriculture. The study was started on April 2002 and ended on September 2007, as part of a national R&D project (AQUATEC). Preliminary results, which we already reported elsewhere, concerned the first two project years while this paper refers to the subsequent period. Three ...

  • Evaluation of the test of significant toxicity for determining the toxicity of effluents and ambient water samples

    The test of significant toxicity (TST) is a hypothesis‐testing approach based on bioequivalence developed by the U.S. Environmental Protection Agency (U.S. EPA) for analyzing whole‐effluent toxicity (WET) and ambient toxicity data. The present study compares results of acute and chronic toxicity tests of effluent, storm‐water, and ambient (i.e., receiving‐water) samples using both the TST and ...
