  • Solvent Recovery South of the Border

    With the advent of NAFTA, Mexico's package-printing industry, a major source of VOC emissions, is under increasing pressure to comply with envronmental regulations. One company, Grafo Regia, pursued an air pollution control process that has an economic payback compared to traditional oxidation. Volatile organic compounds (VOC’s) find wide spread use in the gravure printing and flexible package ...

Background Bailey Motors and Panel Works Pty Ltd operates a ...


  • Recovery and Distillation of Used Wash Solvent: Wattyl Australia

    It took Wattyl Australia just one year to recoup a $100,000 investment in a distillation unit that recovers solvent used in cleaning tanks and equipment in plants manufacturing solvent-based paints. It is now enjoying the ongoing savings as an addition to its bottom line. Instead of paying someone to dispose of the valuable solvents, the company is recovering 90% of the solvent and using it to ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Reduction in Solvents for Cleaning: Amcor Packaging (Australia)

    Background Amcor Cartons, a manufacturer of folding cartons and paperboard packaging is a 13 million dollar operation employing 60 staff. In keeping with Amcor Cartons’s commitment to respond to customer needs through the application of the highest technology, advantage was taken of the latest available technology when deciding to upgrade their printing press. After installing a new ...


  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • Determination of PBDEs in Sediment Samples using Pressurized Solvent Extraction and Automated Soxhlet Extraction

    The efficiency of pressurized solvent extraction (PSE) was investigated by comparing PSE with automated Soxhlet extraction. Sediment samples containing polybrominated diphenylethers (PBDEs) were processed in the SpeedExtractor E-914 for PSE and the Extraction System B-811 for automated Soxhlet extraction. Quantification of PBDEs was performed by GC-MS. This study shows that both techniques are ...

  • A simple and fast micromethod for the analysis of polychlorinated biphenyls in air by sorbent enrichment and ultrasound-assisted solvent extraction

    Abstract  A combination of sorbent enrichment and ultrasound-assisted solvent extraction has been used to determine polychlorinated biphenyls in air. Analytes were sampled by pumping a known volume of air through a porous polymer (Tenax TA). The enriched adsorbent was transferred into a glass vial, and ultrasound-assisted extraction of the analytes was then performed in ...

  • Optimizing the recovery of copper from electroplating rinse bath solution by hollow fiber membrane

    This study aimed to recover and remove copper from industrial model wastewater solution by non-dispersive solvent extraction (NDSX). Two mathematical models were developed to simulate the performance of an integrated extraction–stripping process, based on the use of hollow fiber contactors using the response surface method. The models allow one to predict the time dependent efficiencies ...

  • Ivey-sol technology has potential to increase oil recovery of oil-sands waste by 15-25 percent

    Alberta’s oil sands are comprised of one of the world's largest sources of bitumen, containing an estimated 1.6 trillion barrels. About two tonnes of oil sands must be dug up and processed to produce one barrel of oil. Oil sands recovery processes include extraction and separation systems to remove bitumen from sand and water. Separating the oil from the sand is difficult and costly, and getting ...
