  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Quantifying struvite formation in Calgary’s wastewater treatment system

    The paper presents a sampling and sample preparation protocol to evaluate struvite formation in the solids processing train of a wastewater treatment plant. The protocol was applied to the City of Calgary’s Bonnybrook and Fish Creek WWTP’s and the Shepard Sludge Lagoons. The soluble and particulate portions of magnesium, nitrogen and phosphorus (the chief components of struvite), as well as ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Slug of Hydrocarbon contaminating amine case study

    A Gulf Coast refinery’s amine system was contaminated with up to 3% hydrocarbon. The contamination consisted of hydrocarbon from upstream process units and particulate. The hydrocarbon consisted of LCO and heavy diesel. The current system consisted of an undersized flash tank and a 20% slipstream filtration. The current system could not remove the contaminants so the refinery had to ...

  • 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 ...

  • Project profile - uranium treatment system Middletown Springs Elementary School Vermont

    Background The Middletown Springs Elementary School in Vermont is located in an area of the U.S. very susceptible to the formation of naturally-occurring uranium. Due to the high levels of uranium detected in the well water serving the School, it was placed on a “Do-not-Drink Advisory”. AdEdge was contacted by Otter Creek Engineering in June 2009 to assist the School in ...

  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...
