  • PeCOD® Case Study: 15 Sewer Use By-Law Monitoring: Batch Release Tracing City of Austin, Texas

    Municipal wastewater treatment plants are designed to process a calculated range of organic loading in the raw influent. The calculation of this loading is based on characteristics of the plant’s region, such as population and industry type. Organic loading is most often quantified by the concentration of parameters such as Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), ...

  • Global experiences in optimizing biofouling control through Pulse-Chlorination®

    ABSTRACT Cooling water systems provide optimal conditions for settlement and growth of fouling species, e.g. mussels, oysters and barnacles. Excessive biofouling results in major operational upsets and even unplanned shutdowns. Controlling micro- and macrofouling organisms in once-through cooling water systems is key for safe reliable operation. For this, chlorination is globally still ...

  • Comparison of droplet digital PCR and quantitative PCR for the detection of Salmonella and its application for river sediments

    Despite advances in microbial detection that quantitative polymerase chain reaction (qPCR) has led to, complex environmental samples, such as sediments, remain a challenge due to presence of PCR inhibitors. Aquatic sediments accumulate particle-bound microbial contaminants and thereby reflect a cumulative microbial load over time. The relatively new droplet digital PCR (ddPCR) has emerged as a ...

  • peCOD is the New NOM Monitoring Tool for Measuring Organic Reactivity - Case Study

    Natural organic matter (NOM) is a critical parameter for measuring drinking water quality.  Levels of NOM are associated with taste, odour, colour, chemical treatment dosage, and disinfectant by-product (DBP) formation.  There are several tools accepted by drinking water quality experts which are used to evaluate NOM: total organic carbon (TOC), dissolved organic carbon (DOC), UV254, ...

  • Controlling the COD removal of an A-stage pilot study with instrumentation and automatic process control

    The pursuit of fully autotrophic nitrogen removal via the anaerobic ammonium oxidation (anammox) pathway has led to an increased interest in carbon removal technologies, particularly the A-stage of the adsorption/bio-oxidation (A/B) process. The high-rate operation of the A-stage and lack of automatic process control often results in wide variations of chemical oxygen demand (COD) removal that ...

  • Towards a research agenda for water, sanitation and antimicrobial resistance

    Clinically relevant antimicrobial resistant bacteria, genetic resistance elements, and antibiotic residues (so-called AMR) from human and animal waste are abundantly present in environmental samples. This presence could lead to human exposure to AMR. In 2015, the World Health Organization (WHO) developed a Global Action Plan for Antimicrobial Resistance with one of its strategic objectives ...

  • Odorous volatile organic compound (VOC) emissions from ageing anaerobically stabilised biosolids

    Opportunities for the beneficial re-use of biosolids are limited by nuisance odour emissions. Volatile organic compounds (VOCs) from anaerobically stabilised biosolids were measured to identify compounds that could contribute to the overall odour character of nuisance emissions. Flux hood sampling and chemical analysis were used to identify VOCs emitted from biosolids as they were stored in ...

  • Case study - Groundwater monitoring around hydraulic fracturing sites in Colorado

    Hydraulic fracturing or ‘Fracking’ has become more prevalent and controversial in the US in recent years. More than 90 percent of new wells in the US are completed using this method. While it is endorsed by some as a game-changer that promises an increase in the nation’s economy due to energy independence, job creation, and lower energy prices; others are calling for a temporary ...

  • E-Z Trays® Treating Multiple Groundwater Contaminants in Grand Island, NE - Case Study

    The U.S. Environmental Protection Agency has launched an effort to treat contaminated groundwater in Grand Island, Nebraska. The Parkview Well Superfund Site consists of two areas of groundwater contamination, the Northern and Southern Plumes, which include several volatile organic contaminants including tetrachloroethene (PCE), 1,1-dichloroethene (DCE), 1,1,1-trichloroethane (1,1,1-TCA) and ...

  • Evaluation of PFCA removal by SAT using a pilot-scale reactor

    Wastewater reuse using soil aquifer treatment (SAT) is a rational and realistic solution in countries and regions with limited freshwater resources. The behaviour and removal of perfluoroalkyl carboxylic acids (PFCAs) under long hydraulic retention times (HRTs) in SAT may warrant further investigation. In this study, actual treated effluent from a wastewater treatment plant (WWTP) was ...

  • Biological monitoring system, iTOXcontrol, continues in Scarlino - Case Study

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...
