  • LG Sound integrates new technology to detect toxic algae blooms

    LG Sound introduces satellite remote sensing technology in order to detect toxic algae blooms. Satellite remote sensing allows for detection of water quality from a distance with information obtained from satellites. Together with several European universities we discovered that different types of algae require different types of ultrasonic treatment. Therefore, it is important to detect ...

  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • Modern water`s toxicity monitor used for river clean-up research case study

    Modern Water pic (AIM:MWG), the owner of leading water technologies for the production of fresh water and monitoring of water quality, has collaborated with the Unwersity of Central Florida (UCF) to supply a Microtox® M500 toxicity monitor. The monitor will assist with research into acVanced treatment techniques which could provide a solution to the removal of Total Phosphorus from the Middle ...

  • Online Instrumentation to Protect Wastewater Facilities from Toxic Chemicals

    ABSTRACTSecurity concerns are driving current research to develop means of detecting toxic chemicals in wastewater influents as few online instruments are currently available for this purpose. Online respirometers such as the STIPTox are the obvious choice using existing, established technology. One of these units was recently used successfully in the WERF project 03-CTS-7S “Feasibility Testing ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Environmental surveillance and monitoring—The next frontiers for high‐throughput toxicology

    High‐throughput toxicity testing technologies along with the World Wide Web are revolutionizing both generation of and access to data regarding the biological activities that chemicals can elicit when they interact with specific proteins, genes, or other targets in the body of an organism. To date, however, most of the focus has been on the application of such data to assessment of individual ...

  • Wastewater Monitoring Equipment for An Airport Group

    CAS DataLoggers recently provided the wastewater monitoring solution for a major airport group based in the UK whose fluid run-off threatened to endanger the aquatic ecosystem near the airports. The commercial airline needed an online device capable of monitoring toxic discharges into local rivers. The airline routinely sprayed de-icer and anti-icer solution onto their aircraft before taking off ...

  • Microbial fuel cell-based biosensors for environmental monitoring: a review

    The microbial fuel cell (MFC) is an innovative technology that was initially designed to harness energy from organic waste using microorganisms. It is striking how many promising applications beyond energy production have been explored in recent decades. In particular, MFC-based biosensors are considered to be the next generation biosensing technology for environmental monitoring. This review ...

  • Evaluation of an automated luminescent bacteria assay for in situ aquatic toxicity determination -Case Study

    A new system for monitoring toxicity TOXcontrol® (MicroLAN BV, The Netherlands) has been used to assess the toxicity of a selection of priority or emergent compounds in the laboratory. In this study, inhibition curves and EC50 – Effective Concentration causing 50% inhibition – of selected compounds (including pesticides, pharmaceuticals, surfactants and metals commonly detected in ...

  • New approaches for monitoring the marine environment: the case of antifouling paints

    Protection of ships hulls against biofouling has been a problem since man began sailing the seas. The most common protections are specially produced antifouling paints. These paints could be broadly classified in three main groups, or generations, depending on the technology applied: first generation copper-based, second generation organotin-based, and the new, third generation, organotin-free ...

  • Water quality monitoring in wetland ecosystems using microbial model communities

    This study reviews the concept of model communities for water quality assessment in aquatic ecosystems. The feeding habits of protozoans were used to unite species into functional, trophic groups. Colonising communities were dominated by bacterivorous Flagellate Species (Sf). A new Index of Periphyton Flagellates (IPF) as an indicator of the trophic status of a water-body was developed. ...

  • The Toxic Effects of Hydrogen Sulfide (H2S) Gas from Sewers on Health & Infrastructure - Case study

    How is Hydrogen Sulfide Created? Hydrogen sulfide emitted from sewers and septic tanks can cause serious health issues. Hydrogen sulfide gas is created and released into the air when waste water remains stagnant for a long period of time, and becomes depleted of dissolved oxygen. Although sewer workers are most likely to be affected by hydrogen sulfide overexposure, people living or ...

  • Monitoring Phenol in Water - Case Study

    The Situation A plant located in the eastern United States manufactures phenolic resin for applications in plastics molding. This plant uses well water for cooling its reaction process and then discharges the water into a local creek. A leak in the reactor and associated cooling equipment would cause phenol and phenolic compounds to contaminate the cooling water. Such a leak could ...

  • Assessing Upstream Process Changes with ATP Monitoring

    While the Biomass Stress Index (BSI) parameter is most often used to reveal when a biological population has been subjected to toxicity, it can also indicate when an upstream change has relieved a stressful condition. In this month’s featured case study, a pulp & paper wastewater treatment plant made a change to its papermaking process that changed the properties of the wastewater ...
