  • Zuser - Polaris 2800 - With Lindner, you know what you’re getting - Case Study

    Zuser Ressourcenmanagement GmbH is not keen on experiments: for the past 24 years the RDF producer in Peggau, Austria has bought shredders made by Lindner Recyclingtech. The new addition to the family is a Polaris 2800. For one-step shredding every other machine was simply out of the question. The cooperation with Lindner dates back to a time before Mag. Georg Zuser became CEO of the Zuser ...

  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • Why Interactive Ultrasonic Programs are Important to Effectively Control Algae

    Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively  ...

    The UK’s 25 largest pension funds, representing £555bn of assets under management, were yesterday asked to explain to a select committee how they handle the risks that climate change pose to savings. ...

  • Why Air Quality Specialists Should Measure for Sulfur Dioxide (SO2) in Homes & Offices - Case study

    What is Sulfur Dioxide? (SO2) Sulfur Dioxide (SO2) is a highly reactive gas that is part of a larger group of sulfur oxides or SOx gases. According to the U.S. Environmental Protection Agency, the largest sources of SO2 emissions are due to “fossil fuel combustion at power plants (73%) and other industrial facilities ...

  • Silver Membranes in Monitoring Respirable Crystalline Silica

    Crystalline silica, most commonly found in the form of quartz, is a basic component of the earth; it’s found in soil, sand granite, and other minerals. During many industrial processes, crystalline silica is released as particles that are 100 times smaller than beach sand.1 Due to their size, these mineral particles cannot easily be cleared by human lungs. Instead, they persist in the ...

  • BUMP TESTING AMMONIA (NH3) SENSORS

    Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (1-2 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall ...

  • Why monitor dust in the workplace?

    Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the ...

  • Portable Combustion Analyzers as Safety Devices - Case study

    Portable Combustion Analyzers Can Be Used as Safety Tools for Technicians in Residential or Commercial HVAC Applications With all residential and commercial boilers, furnaces, and heaters, there is an inherent risk that cracks in the heat exchanger, improperly maintained ducting systems, or other malfunctions can cause combustion gases to leak into the living or working environment ...

  • 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 ...

  • Why Container Measurements Are Essential

    Transport container traffic carries millions of containers around the globe annually. Cargo containers are fumigated to inhibit the spread of foreign species, pests and micro-organisms. Transported products may also release volatile organic compounds (VOC) from the solvents, coatings and glues used in manufacturing processes.  Work safety regulation requires the ...
