  • Biofilter Applications in the Coatings Industry.

    Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...


  • Two Case Histories of Industrial Water Reuse Via Membrane Technology

    Abstract This paper describes two successful applications of ultrafiltration (UF) and reverse osmosis (RO) membrane technology used to reclaim water, reduce waste water discharge costs. The first case history covers oily waste water treatment at a major aluminum beverage can manufacturing plant. The second case describes treatment of waste water from a multi-plating bath section of a major ...


  • Companies and people leading the restructured environmental services industry in Canada

    The landscape of environmental service providers in Canada has changed dramatically in the past four or five years, especially with mergers and acquisitions announced in recent months between some fast-growing businesses. Only a decade ago the industry was dominated by a couple of publicly-traded continental companies that gobbled up numerous small and medium-size enterprises to offer customers a ...

  • Centralised treatment of oil sludge and other industrial waste - case study

    Centralised treatment of various sources of industrial waste has been established in many European countries over the last decade. Many facilities are still equipped with non state of the art technology and therefore cannot fulfil the broad field of applications with regard to industrial waste remediation, econ's international client decided to be one step ahead and erected a new econ industries ...

  • Oil Water Separator Maintenance

    Oil water separators (OWS) can be co$tly to maintain, $20,000 or more on average per cleaning and if not properly managed, can be very expensive conduits of pollution. Have you taken steps to minimize the effects and consequences on your operating co$t? When was your facility’s last OWS maintenance ...

  • 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 ...


  • What do oil sands and shale gas have in common? Acute need for sustainable water management solutions

    The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

  • 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 ...

  • Evaluating Spiral-wound Separator Performance

    Introduction The recent evolution of spiral-wound membrane element (sepralator) design brings an increased need to understand the intricacies of testing, operating and predicting performance of this most popular crossflow membrane design. After over a decade of stagnant development, the last five years have produced several innovations, which diversify and expand the applications as well as ...


  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • The ecological impact of membrane-based extraction of phenolic compounds – a life cycle assessment study

    Many phenolic compounds show high boiling points, low molecular weights, moderate polarities or high toxicities. Therefore, conventional wastewater treatment is limited or expensive. Recycling of the separated compounds is often not possible. But, if liquid-liquid reactive extraction is linked to a non-porous membrane, some or all of the above mentioned limitations may be overcome. The key ...

  • 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 ...

  • Case study - Waste site cleaned with one-pass trenching technology

    Waste site cleaned with one-pass trenching technology. An abandoned sand and gravel quarry, with a dubious second use as an industrial waste disposal dumping ground, has been cleaned up with the aid of a technology known as the one-pass trenching method. The site had accepted distillation wastes from a local solvent recycler. Due to odours, the dumping prompted citizen complaints that eventually ...
