  • 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- ...

  • Biomonitoring can measure what chemical monitoring cannot

    Algae and Daphnia (waterfleas) forewarn drinking water sector Biomonitors, instruments which measure the biological effects of different substances on organisms, detect substances which cannot be detected using chemicals anaylsis methods. This is also valid for combinations of substances which are present in the water in large concentrations. A well-functioning monitor is necessary since our ...

  • Towards a European Chemicals Information System: a survey on reported monitoring activities of chemicals in Europe

    This report presents the outline and results of a project which collected information on monitoring activities in the 32 EEA member countries. In addition, a framework is proposed on the potential structure of a multi-purpose European chemicals information system where a database on monitoring activities would constitute one element. The system could be used as a tool in support of EU chemicals ...

  • Air Pressure Monitoring for a Chemical Fume Hood

    CAS DataLoggers recently provided the pressure and temperature datalogging solution to a manufacturer using a chemical fume hood to protect workers by containing vapors, dusts, gases, and fumes, and then expelling them as air flowed into the hood from the front (open) side of the cabinet and then out via the ducted hood exhaust system. Designed for 2 operators, the fume hood had a Fiberglas ...

  • Chemical Corner

    So, you’re well aware of all REACH and CLP regulations and you’ve gone to great lengths to ensure your operations and products are compliant with EU regulation. That’s great news. But in the case of Europe, that’s not where the regulations end. Beyond these requirements, you often have to comply with additional, country-specific rules to import, manufacture or sell ...

  • Chemical monitoring strategy for the assessment of advanced water treatment plant performance

    A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was ...

  • Water Distribution System Security Monitoring

    A water security instrument essentially needs to be able to detect potential contaminants in drinking water. Since a significant number of potential chemical contaminants are organic in nature, a water security monitoring instrument that can detect organic matter in water is perfect for this application. Real Tech has developed an instrument specifically designed for water security ...

  • A pump-less discrete opto-fluidic chemical spectrophotometry system (DOCSS) for online in situ monitoring of dissolved contaminants in aqueous media

    This paper presents the fabrication of a discrete chemical analyzer system for online monitoring of dissolved ions in water using UV-VIS absorption spectrophotometry. The device is composed of three main components: fluidic, optical, and control. The test cell was designed to also function as a non-invasive volume sensor, and the volume sensing principle was based on light scattering by ...

  • Implementation of an automatic and miniature on-line multi-parameter water quality monitoring system and experimental determination of chemical oxygen demand and ammonia-nitrogen

    An automatic, miniature and multi-parameter on-line water quality monitoring system based on a micro-spectrometer is designed and implemented. The system is integrated with the flow-batch analysis and spectrophotometric detection method. The effectiveness of the system is tested by measuring chemical oxygen demand (COD) and ammonia-nitrogen in water. The results show that the modified system ...

  • Contemporary design, operation, and monitoring of potable reuse systems

    Water scarcity driven by population growth, lack of conventional supplies, and climate change impacts have resulted in increasing interest worldwide in drinking water augmentation using treated wastewater effluents. Potable reuse can occur indirect or direct, but is also practiced in many places as ‘de facto reuse’, where upstream wastewater discharge occurs to drinking water ...

  • Sewer Level Monitoring System - a case study

    Background - The business of sewage level monitoring in sewers is accelerating across many countries. Strict regulations, the need to avoid environmental disasters, violation fines, early warnings and planning needs are just some of the forces shaping this growing trend.   Challenges Quantifying sewage flow and level is one of the most ...

  • China in Talks to Join the OECD System for the Mutual Acceptance of Data in Assessment of Chemicals

    It has recently been reported that China is in discussions with the Organization for Economic Cooperation and Development (OECD) to become a provisional adherent to the Mutual Acceptance of Data (MAD) system. This would require China to accept data from safety testing of chemicals from participating countries generated under the MAD conditions and to establish a Good Laboratory Practice (GLP) ...
