  • Hydrogen Chloride Analyzer (HCl, H2O)

    LGR's Hydrogen Chloride Analyzer (HCl, H2O) provides sensitive measurements of HCl in ambient air or in industrial process flows (e.g., coal and cement exhaust streams) with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time to measure HCl with extremely high sensitivity – LGR's HCl Analyzer provides measurements every second with ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • Struvite and Vivianite Screw Presses and Heat Exchanger Removal case study

    A regional wastewater treatment plant in Sonoma County was experiencing problems with struvite on their screw presses and vivianite on their heat exchangers. The design plant flow rate is 7.9 mg/day. They were using 7 mg/L to 10 mg/L (dry basis) of ferric chloride to control hydrogen sulfide and improve solids removal in the primary clarifier. The plant maintenance staff was forced to shut down ...

  • Sequential Extraction Procedure

    Sequential extraction is an analytical process that chemically leaches metals out of soil, sediment and sludge samples. The purpose of sequential “selective” extraction is to mimic the release of the selective metals into solution under various environmental conditions. One commonly used sequential extraction procedure is designed to partition different trace metals based on their ...


  • San Joaquin Valley California - Arsenic removal from ground water

    Background The San Joaquin Valley of California is approximately 220 miles long and varies in width to a maximum distance of approximately 80 miles. The occurrence of groundwater over the entire extent of the valley is abundant. Recharge for the varied depths of aquifers is from precipitation in the form of rain and the snow pack from the western Sierra Nevada Mountain Range. High ...

  • Factors Affecting Cyanide Generation in Chlorinated Wastewater Effluent Matrix

    ABSTRACTFalse positives for cyanide analysis in wastewaters have been reported. We examined the effects of storage time at high pH and of pH adjustments on the cyanide levels. Cyanide levels changed within the holding time allowed by Standard Methods. We also studied the difference in cyanide levels using two disinfection conditions -- breakpoint chlorination and chloramination. Glycine was used ...

  • A Chemical Dynamics Model for CAH Remediation with Polylactate Esters.

    ABSTRACT: The polylactate esters of sorbitol, xylitol and glycerol are a class of new chemical compounds that slowly release lactic acid into groundwater. The lactic acid is biotransformed into pyruvic acid and subsequently into acetic acid releasing hydrogen in both steps. The hydrogen is used by naturally occurring dechlorinating bacteria to reduce PCE to ethene by way of TCE, DCE and VC. A ...

  • High density polyethylene (HDPE) pyrolysis plant

    Thermal degradation of plastic polymers is becoming an increasingly important method for the conversion of plastic materials into valuable chemicals and oil products. In this work, virgin high-density polyethylene (HDPE) was chosen as a material for pyrolysis. A simple pyrolysis reactor system has been used to pyrolyse virgin HDPE with an objective to optimize the liquid product yield at a ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Introduction to Ion Exchange Part 1

    IMPURITIES IN WATERWater is often referred to as the 'universal solvent' as it will dissolve small amounts of everything it touches. Water collects or dissolves a variety of mineral salts, organic compounds and suspended solids as it flows over the earth's surface and through the ground. These impurities make water undesirable for use in many applications. It is, therefore, important to ...

  • Field Application of a Lactic Acid Ester for PCE Bioremediation.

    ABSTRACT: As part of a strategy to enhance reductive dechlorination with a timed release of hydrogen, an application of glycerol polylactate (GPL) was made to a dry cleaner site contaminated with perchloroethylene (PCE). GPL is one of several proprietary lactic acid esters sold commercially as Hydrogen Release Compound (HRCTM). When HRC contacts the saturated contaminated zone, the lactic acid ...
