  • Concentration and solvent recovery of environmental samples in dichloromethane

    Environmental samples are usually extracted with an organic solvent which is then concentrated prior to final analysis. In this short note, initial conditions and evaporation settings for the parallel concentration of samples dissolved in dichloromethane (DCM) having different starting volumes are presented. These settings have been optimized for high analyte and high solvent recoveries. ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • Solvent Recovery System Keeps Presses Rolling at World`s Largest Gravure Printing Plant

    When QUAD/GRAPHICS Inc. entered the publication gravure printing market, it followed the axiom of Daniel Burnham, the 19th century architect and urban planner, to 'make no small plans.' In 1985, the Pewaukee, Wis.-based printing company purchased two 96-inch web, eight-color, high-speed presses and installed them at its new printing plant in Lomira, Wis., near Milwaukee. Conventional wisdom at ...

  • Selective recovery of heavy metals from hot-dip galvanising effluent streams by membrane-based solvent extraction

    The hot-dip galvanising process produces a large quantity of acidic effluent high in iron, zinc and chloride ions. The current method for disposal of the waste acid is to neutralise the remaining hydrochloric acid (HCl) to precipitate a worthless, environmentally harmful mixture of iron and zinc hydroxides that be disposed of to specialised landfill sites. The recovery of any of these species is ...

  • Integration of ceramic membrane and compressed air-assisted solvent extraction (CASX) for metal recovery

    In our previous publications, compressed air-assisted solvent extraction process (CASX) was developed and proved to be kinetically efficient process for metal removal. In the current study, CASX with a ceramic MF membrane integrated for separation of spent solvent was employed to remove and recover metal from wastewater. MF was operated either in crossflow mode or dead-end with intermittent ...
