  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Raw material cycle: from chip to briquette to product - Case Study

    Thanks to their briquetting system from RUF Frischhut can redeploy production scrap and melt it again Ludwig Frischhut GmbH and Co. KG have closed the circle on their raw material cycle by utilising a briquetting press from RUF: cast chips produced during the machining of parts for water supply and sewage disposal are pressed to solid briquettes and then melted in the in-house foundry and ...

  • Electrokinetic Separation

    Introduction The principle of electrokinetic remediation relies upon application of a low-intensity direct current through the soil between ceramic electrodes that are divided into a cathode array and an anode array. This mobilizes charged species, causing ions and water to move toward the electrodes. Metal ions, ammonium ions, and positively charged organic compounds move toward the cathode. ...

  • Titanium Scrap Metal Processing

    Background A world-class processor of titanium scrap had a wash system whose cleaning solution was becoming contaminated with both free floating unemulsified tramp oil and emulsified water soluble oil that was being washed off of titanium turnings. As the level of oil contamination increased over time in the wash solution, cleaning effectiveness diminished. The processor uses a metric, ...

  • Heavy Metals in Waste

    Untitled Document Summary and discussion The aim of this report has been to demonstrate the existing knowledge regardng the harmful effects of heavy metals, the ...

  • Remediation of Metals-Contaminated Soils and Groundwater

    A range of technologies is available for remediation of metals-contaminated soil and groundwater at Superfund sites. General approaches to remediation of metal contamination include isolation, immobilization, toxicity reduction, physical separation and extraction. These general approaches can be used for many types of contaminants but the specific technology selected for treatment of a ...

  • Source separated residential composting in the US

    THE Field of Dreams movie theme, “if you build it they will come,” is definitely à propos to source separated residential organics composting. While conducting this year's survey, we asked program managers what they think the key ingredients are to offering households the ability to divert more than just yard trimmings at the curb - a practice that is widely adopted in some Canadian provinces and ...

  • REDWAVE Metal Days 2015 - Review

    The REDWAVE Metal Days, at BT-Wolfgang Binder in Gleisdorf, pro­vided the context for international experts from various sectors of the metal and aluminium recycling in­dustry to exchange information on markets, technologies and practical experience. In addition, the new REDWAVE XRF-M sorting system, for recycling in the metals sector, was presented to the participants. ...

  • Austin AI QXR-M – Technology to improve metal recovery from non-ferrous residues

    Existing technology has been used for some time to separate light non-ferrous alloys from heavier non-ferrous alloys; however, over the past three years, there is a significant added value in performing additional separations to recover specific high dollar alloys. Examples of such are separating pure copper from copper alloys (brass and bronze) or wrought from cast aluminum. The only way to do ...

  • Oxygen-separation membranes could aid in CO2 reduction

    Ceramic membranes may reduce carbon dioxide emissions from gas and coal-fired powerplants. Written by Jennifer Chu, MIT News Office.You can read the original new in MIT NewsIt may seem counterintuitive, but one way to reduce carbon dioxide emissions to the atmosphere may be ...

  • Simple Separation: Diverting Wood And Cardboard at Construction Sites

    Diverting Wood And Cardboard At Construction Sites Residential home construction in Wisconsin generates 128,000 tons of residuals annually, according to a 1998 study by Camp, Dresser & McKee. Ten builders are participating in a project to demonstrate how easily major components of this waste stream can be recycled. The Metropolitan Builders Association (MBA) of Greater Milwaukee, the ...

  • Electrokinetics - Technology Overview

    Electrokinetics separates and extracts contaminants from saturated or unsaturated soils, sludges and sediments, and groundwater. The goal of electrokinetic remediation is to effect the migration of subsurface contaminants in an imposed electric field via electroosmosis, electromigration and/or electrophoresis. These phenomena occur when the soil is electrically charged with a low voltage current. ...

  • Oil and metal recovery from mill scale and grinding swarf for the metal industry - case study

    A combination of rising prices for resources and the improvement in technology make treatment of mill scale and grinding swarf an extremely environmentally friendly and economical solution. The first VacuDry® plant for the recovery of oil solvents and metals from sludges began operating in autumn 2012. Our client is a medium-sized company operating in the field of waste recycling and ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • The process of flotation: an efficient solid/liquid separation technique for biological materials

    The studied innovative wastewater treatment process involved the initial abstraction of heavy metal ions onto fungal or stalks biomass (biosorption), followed by the application of a typical flotation stage for the efficient downstream separation of metal-laden biosorbent particles. The ability of microorganisms to remove metal ions from dilute aqueous solutions is a well-known property. ...
