  • 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 ...

  • Seeking Clarity in Noise

    Environmental noise regulation can be frustrating. The noise limits, applicable measurement metrics, assessment methods and level of enforcement vary a lot by region and jurisdiction and rarely do they all align. Historically, noise emitters and sensitive receivers could afford to use distance to separate themselves. Consequently, environmental noise laws were first developed in regions with high ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • What`s Hiding in Your Waste Piles?

    In over 25 years in the grinding and recycling industry, we’ve learned that there’s always more than meets the eye in a pile of waste materials. Whether it’s a pile of pallets or household garbage, there’s some good and some bad hiding under the surface. It's there if you know how to find it. You can find it with the right industry knowledge, the right equipment, ...

  • Ammonium, nitrate, and total nitrogen determination in fly ash

    Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

  • Wastewater and groundwater

    Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With ...

  • 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 Power to Separate

    Gravity separators are effective and economical tools used to process wastewater and stormwater by removing pollutants such as sediment, hydrocarbons and debris through the process of sedimentation or flotation. Most separators have few or no moving parts, are easy to maintain and have a successful history of use in many different industrial, commercial and residential applications. Specifying ...

  • Not all oil water separators are created equal

    Efficiency is meaningless unless engineers and maintenance professionals are able to sustain it for a long periods of time. This webinar addresses three major questions: How do I prevent my company from incurring fines and citations? How do I increase the time between maintenance/cleaning schedules and stMl produce satisfactory effluent? How do I save my company money in regard ...

  • 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 ...

  • Magnetic Separation Myths 2 of 10 – Are All Rare Earth Magnets the Same?

    A client has a metal contamination problem and needs to install the most suitable magnetic separation.  The metal is small and so they believe that a Rare Earth Magnet is what they need as this produces the strongest magnetic field.  So he picks up the phone and orders a Rare Earth Magnetic Separation and his problem is solved.  Or is it? Unfortunately, the term ‘Rare Earth ...


  • The dangers of separating science and environment

    We need to figure out a better way to communicate science that balances technology and nature. Does the natural world have any relevance to modern science? Of course it does; but sometimes it seems like that’s not the case. This is a myth perpetuated directly and indirectly through media, policy decisions, academic disciplines, even some science engagement initiatives: ...

  • 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 ...

  • Source separation trends in the UK

    THE past 15 years have seen significant investment and development of the biowaste collection and treatment industry in the United Kingdom (UK), which has gone from virtually zero to an industry worth over £160 million (264.6 million USD). Driving this investment have been a number of regulatory and fiscal measures such as the first set of Landfill Directive targets due in 2010. Since 1999, the ...

  • 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, ...
