  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Efficiency and reliability of membrane processes in a water reclamation plant

    Performance of a water reclamation plant using ultrafiltration (UF) and reverse osmosis (RO) treating 280,000 m3/d of wastewater was evaluated over 1 year. Statistical analyses were performed on flow rate, temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), biochemical oxygen demand (BOD5) and total coliforms. Variations in flow rates coincided with those in ...

  • Degradation of azo dyes in water by Electro-Fenton process

    Abstract The degradation of the azo dyes azobenzene, p-methyl red and methyl orange in aqueous solution at room temperature has been studied by an advanced electrochemical oxidation process (AEOPs) under potential-controlled electrolysis conditions, using a Pt anode and a carbon felt cathode. The electrochemical production of Fenton's reagent (H 2O 2, Fe 2+) allows a controlled in situ generation ...

  • Efficiency Improvements in Water Treatment Process: Aqwest-Bunbury Water Board

     Aqwest-Bunbury Water Board has introduced a range of cleaner production measures designed to improve the overall efficiency of its water treatment plants. Background Aqwest, the operating arm of the Bunbury Water Board, supplies water to approximately 12,000 service connections for the 30,000 residents of the town of Bunbury, Western Australia, 180km south of Perth. ...


  • Effects of mixing on chloramination process

    According to a recent study more than 90 percent of water treatment plants utilizing chloramination for distribution system residuals indicate a certain level of dissatisfaction toward the process performance. One factor that may lead to such dissatisfaction is the inadequacy of mixing when ammonia is added to chlorinated water. If mixing is not instantaneous and uniform, the actual chlorine to ...

  • Flexible data management helps in regulatory compliance, by Colin Thurston, director of product strategy, process industries, thermo fisher scientific

    In the US state of Florida, the public regional wholesale water provider Tampa Bay Water and Veolia Water North America completed a 454,000 cubic meters (120 million gallons per day) water treatment plant that exceeds federal and state drinking water quality standards. The design, build, and operate (DBO) approach helped to save US$80 million and kept the project on schedule.The Tampa Bay Water ...

  • Exploring runoff processes using chemical, isotopic and hydrometric data in a discontinuous permafrost catchment

    Hydrometric, isotopic and hydrochemical data were used to investigate runoff generation in a discontinuous permafrost headwater catchment. Research was undertaken between 10 April and 8 July 2008 within Granger Basin, a 7.6 km2 sub-catchment of the Wolf Creek Research Basin, Yukon Territory, Canada. The objectives of this research were to utilize hydrometric, stable isotope and hydrochemical ...

  • Co-Metabolic Processes

    Introduction: Co-metabolism is one form of secondary substrate transformation in which enzymes produced for primary substrate oxidation are capable of degrading the secondary substrate fortuitously, even though the secondary substrates do not afford sufficient energy to sustain the microbial population. An emerging application involves the injection of water containing dissolved primary ...

  • Hydrometric Network Data Management

    A key part of HL's contract with Dwr Cymru Welsh Water to install, operate and maintain a large network of telemetred reservoir level and compensation flow gauges, a suite of HL's software packages was also supplied to each of the three operational areas for managing time-series data and processing stage-discharge data into a long-term flow record archive. HL's HydroLog4 and Gauger 2 packages ...

  • Big data and hydroinformatics

    Big data is popular in the areas of computer science, commerce and bioinformatics, but is in an early stage in hydroinformatics. Big data is originated from the extremely large datasets that cannot be processed in tolerable elapsed time with the traditional data processing methods. Using the analogy from the object-oriented programming, big data should be considered as objects encompassing the ...
