  • 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 ...

  • The application of flotation for the downstream separation of metal-loaded microorganisms

    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. ...

  • Dyed viruses and metal particles for advanced separation studies

    Single nanometer sized particles are poorly retained by conventional water treatment methods and are hardly detectable in water samples. The particles present a separate class of pollutants and their transport and fate cannot be studied by tracking bacteria, turbidity, free dyes or ions. Dyed bacteriophages and gold nanoparticles are two novel tools that facilitate the studies of virus ...

  • 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. ...

  • The true value of magnetic separators and metal detectors in bulk handling

    Introduction The purpose of a bulk material handling may be to transport material from one of several locations to an ultimate destination or to process material such as ore in concentrating and smelting or handling materials for manufacturing. The handling of dry materials in loose bulk form involved the extensive use of static machinery such as belt conveyors, screw conveyors, and various ...

  • Separation of metals and phosphorus from incinerated sewage sludge ash

    Microbial acidification of incinerated sewage sludge ash and dissolution of metals from the acidified ash were investigated using a semi-batch reactor at different solid retention times (SRTs). The average pH values ranged from 0.91 to 1.2 at SRTs longer than 10 days, whereas the reduction of SRT to 4 days resulted in an increase in the pH value to about 2. The dissolution efficiencies of Al, ...

  • Recovery Of Metals Using Combustion

    Process industries generate a number of hazardous waste streams containing metals bound with organic components. These metals can be quite valuable if they can be separated from the organic components and recovered. Four projects are discussed. ...

  • Scrap Metal Recycling 1

    Integrated Engineers provided treatability services for the facility for three areas onsite: the oil water separator, tin baler effluent water, and aluminum shavings/cutting oil runoff. The facility processes and bales scrap metal for recycling. The three different waters were treated with Floccin J. Oil Separator The oil separator water is used to remove any free oil that is floating on top of ...

  • Sintered Metal Manufacturing 1

    This facility generates 2 waste streams from their metal sintering operations. The first waste stream comes from their cutting oil operations and rinse water. The wastewater is then stored in several tanks and allowed to partially separate with some of the floating oil skimmed off. The residual wastewater (3,000 gallons/week) is then hauled off site for disposal at $1.15/gallon. The treatability ...

  • Heavy Metals in Vehicles

    Untitled Document Introduction Starting from September 1999, Ökopol has been performing a study on heavy metals in vehicles which was commissioned by DG ...

  • 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, ...

  • Separation of some heavy metal species from electroplating rinsing solutions by ion exchange resin

    A strongly basic anion exchange lewatit MP 600 resin was tested to separate metal species from electroplating rinsing wastewater. An azo resorcinol 4–(2–pyridylazo) dyestuff was used as a complexing agent. Adsorption isotherms were modelled in an ethanol/acetic acid/water media. The loaded resin is regenerated using 4 M HCl whereby the eluted metal species are recovered. Results revealed that ...

  • Magnetic Separation Myths 3 of 10 – The Highest Gauss Magnetic Separator is the Best!

    On a weekly and often daily basis, an enquiry will arrive in one of the Bunting team’s inboxes requesting a Magnetic Separator (eg a Cartridge or Tube Magnet) of a specific length and diameter.  It is only when the enquiry also states a specific gauss figure that the complications start. Firstly, ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...
