  • Application of Lab-on-a-chip Technology in Water Analysis

    The Important of Water Analysis Water analysis is essential to ensure its quality or to detect pollutants that should be removed by water treatment. However, water quality does not mean making the water suitable for human consumption; it depends on its end use. For example, completely different quality standards are applied in case of industrial water compared to those ...

  • Automotive parts manufacturer - Eaton US engine valve case study

    Scope US Engine Valve in SC had 16 small washing systems that were used to wash parts after machining with straight oil as the metalworking lubricant. These wash tanks were dumped and recharged weekly and the oil concentration in the washers climbed between cycles to 5% before dumping at the end of the week. During this cycle, the part tolerance measuring equipment could be adversely ...

  • Swabbing Water Lines – A Better Level of Water Awareness

    We know that biofilm is a tricky thing. It grows quickly, harbors bacteria, protects that bacteria from cleaning agents, and then releases those bacteria back into the water, potentially causing severe health issues. We clean and sanitize regularly to try to keep it controlled, but how can we know how much bacteria are actually inside the pipes? Doing a drip sample gives us just a vague idea. ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...

  • Desert Sands MDWCA #4, New Mexico - Case Study

    In August 2008, AdEdge Water Technologies was contacted by the engineering firm Bohannan Huston to design, supply and start up an arsenic and iron removal system for Desert Sands MDWCA Well #4 in Anthony, New Mexico. The water chemistry had an arsenic level of 17 to 20 ppb and a naturally occurring iron level of 1 mg/L that will facilitate co-precipitation and removal of arsenic. AdEdge was ...

  • Wastewater Mining and Reuse: Creating Benign Future Scenarios

    Wastewater mining: In addition to being perhaps the most uninviting combination of words, it sounds like a most unlikely idea. But for almost 30 years, Aqueonics, now headquartered in Greenville, SC, has pioneered such systems, starting in the ’80s, with its first wastewater mining project. For that project, Aqueonics provided an onsite or decentralized treatment system for a developer in ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • Large Volume Splitless Injection Using an Unmodified Split/Splitless Inlet and GC-TOFMS for Pesticides and Brominated Flame Retardants

    Abstract Large volume splitless injection for gas chromatography typically requires a special injection port, for example, a programmable temperature vaporizer (PTV), but an alternative setup using concurrent solvent recondensation–large volume splitless injection (CSR-LVSI) and a split/splitless injection port has been reported. This technique was used here, both with and without ...
