  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • Real-Time Membrane Fouling Monitoring

    The Port Hueneme Water Agency (PHWA) has been operating a municipal drinking water treatment plant designed to be a Brackish Water Reclamation Demonstration Facility. The facility consists of 3 separate side-by-side full scale systems or trains, each representing a major membrane separation process: nanofiltration (NF), reverse osmosis (RO) and electro dialysis reversal (EDR). Both the NF and RO ...

  • A real-time operation of the Three Gorges Reservoir with flood risk analysis

    Risk analysis is essential to reservoir operation. In this study, a new analysis for reservoir operation is proposed to enhance the utilization rate of the flood water from the Three Gorges Reservoir (TGR) during the flood season. Based on five scenarios of hydrology forecasting with the adaptive neuro-fuzzy inference system (ANFIS), a multi-objective optimum operation was implemented ...

  • 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 ...


  • Real-time Total Microbial Measurement For Water Distribution Systems

    A well-managed water distribution system is essential for maintaining a healthy water supply. The World Health Organization, the directing and coordinating authority on health (World Health Organization, 2008), has compiled the Water Safety Plan which reflects this. With over 2.3 million deaths per year caused by water born diseases (Davidson, et al., 2005), safeguarding water systems is of ...

  • Radio Solution brings real-time monitoring benefits for water supplier

    Introduction of wireless data collection and analysis improves leak detection and water supply efficiency Companies whose business is the delivery of water to consumers, do not only have a responsibility to provide high quality drinking water to both domestic and industrial users, but also to ensure that it is done so economically and reliably. The WLV association ...

  • How to make top-down and bottom-up sustainability converge

    Fits and starts are all too common in the sustainability world. One year you have budget for initiatives; the next you don’t. Management hails cost savings on individual projects, but they miss the big picture and fail to link progress across departmental boundaries. Bottom-up progress and top-down directives pass each other like proverbial ships in the night. But it doesn’t have to ...

  • Thoroughly modern installers keep on industry trend

    The ErP Directive, through its various iterations since 2009, not only places high demands on the efficiency levels of a wide range of heating products, and especially hot water storage in our homes, but also on installers to communicate the benefits of greater energy efficiency to their customers. If the target to reduce energy use by 20% by 2020 is remotely realistic, not only has product ...

  • Changing the Rules with Mass Detection

    How simplified detectors can provide mass data for every analytical run and speed up method development With access to multiple mass spectrometry systems of varying degrees of sophistication, Davy Guillarme (University of Geneva, Switzerland) wasn’t actively looking for new mass detection solutions. Nevertheless, the Waters ACQUITY QDa mass detector caught his eye. Why? Because it opens a ...

  • Rapid and specific detection of Salmonella in water samples using real-time PCR and High Resolution Melt (HRM) curve analysis

    A real-time PCR assay combined with a pre-enrichment step for the specific and rapid detection of Salmonella in water samples is described. Following amplification of the invA gene target, High Resolution Melt (HRM) curve analysis was used to discriminate between products formed and to positively identify invA amplification. The real-time PCR assay was evaluated ...

  • AquaLab Analyzer provides real-time phosphorus measurement in Everglades

    When it comes to ecosystem sustainability, Florida is no backwater. The South Florida Water Management District, which includes the unique Everglades habitat, had a major challenge. The EPA and various governmental authorities have defined limits for many water quality parameters to support a water body’s designated use. Any physical, chemical or biological condition that threatens the designated ...

  • Water analysis

    A complete tap water analysis includes the determination of the pH value, the alkalinity and the total water hardness. Both the pH measurement and the pH titration by means of a standard pH electrode suffer from several drawbacks. First, the response time of several minutes is too long and, above all, the stirring rate significantly influences the measured pH value. Unlike these standard pH ...
