  • Soil-transmitted helminth eggs assessment in wastewater in an urban area in India

    Water quality and sanitation are inextricably linked to prevalence and control of soil-transmitted helminth infections, a public health concern in resource-limited settings. India bears a large burden of disease associated with poor sanitation. Transformative onsite sanitation technologies are being developed that feature elimination of pathogens including helminth eggs in wastewater ...

  • Microbes Run the World

    Microbes run the world. They are the governing agents behind the conversion of key elements into vital biological forms. They remove toxins from their environments, and protect us from disease-causing organisms. Microbes do not, however, go to battle alone. Microbe armies live in complex communities that follow intricate processes and interactions to ensure environmental stability. Until ...

  • Analysis of PeCOD Technology and Comparison to Dichromate Method

    Abstract The main objective of this report was to determine if a correlation exists between peCOD technology and the dichromate method of estimating Chemical Oxygen Demand (COD). Additional investigations described in this report were: to identify whether particle size in water samples affects the estimate of COD obtained by peCOD analysis and, to identify whether peCOD analysis is ...

  • Assessing antibiotic resistance of microorganisms in sanitary sewage

    The release of antimicrobial substances into surface waters is of growing concern due to direct toxic effects on all trophic levels and the promotion of antibiotic resistance through sub-inhibitory concentration levels. This study showcases (1) the variation of antibiotics in sanitary sewage depending on different timescales and (2) a method to assess the antibiotic resistance based on an ...

  • Latex Manufacturer Wastewater Case Study

    Targeting TSS and Achieving Clarity The wastewater sample when received was a pH of 10.3. The request for a wastewater solution was to remove TSS and obtain better water clarity. Various Floccin blends were used until the water clarity was acceptable. Better results were obtained combining the two types of wastewater and performing the jar test. The recommended ...

  • Detection and subtype identification of Blastocystis isolates from wastewater samples in the Philippines

    To provide further evidence of waterborne transmission of Blastocystis, a total of 31 wastewater treatment plants from geographically distinct locations across the Philippines were sampled for influent and effluent sewage samples. In vitro cultivation was the method of choice to increase sensitivity of detection. Blastocystis cysts were detected in 15% (9/62) of ...

  • Spackling Adhesive Manufacturer

    Floccin J was used to treat these samples of spackling compound wastewater. The sample was at a neutral pH and required no pH adjustment. The Floccin-J was added at a dosage of 0.12 grams in 100 ml of wastewater. For a 1,000- gallon batch treatment, this would equate to a chemical cost of $15.00 with excellent water clarity that could be reused in the ...

  • Wastewater dephosphorization using crude clays

    The present work aims to establish the possibility of using local clays to treat wastewater. Thus, three clay samples extracted from two localities in the south of Côte d’Ivoire have been studied in their crude state. The qualitative physicochemical study that consisted in measurement of pH variation and argillaceous particles zeta potential showed that the Nieki-Agneby clay and the Beige Anyama ...

  • Oil Drilling Operation Wasteawater Treatment

    Wastewater Treatment Success Stories Oil Industry Operation Wastewater Treatment Wastewater on a self-contained drilling platform comes from several sources. The following examples are samples obtained from the ...

  • Biodegradation Tests for Wastewater Samples

    Biodegradation Tests for Wastewater Samples Biodegradation tests usually involve comparison of the oxygen uptake of a test sample – or gas production for anoxic or anaerobic tests – to that for a readily biodegradable control substrate (usually acetic acid, ethanol, or aniline). While biodegradation characteristics can vary among chemical types and wastewater sources, typical patterns are shown ...

  • Design and Evaluation of a Flow Pump System for Column Testing

    The design of the equipment components of a flow pump system for the measurement of solute (effluent) breakthrough curves from soil columns is described. In addition, the performance of the system in terms of the effects of equipment components and temperature on measured differential pressure fluctuations across soil specimens is illustrated. The flow pump for the system provides continuous flow ...
