  • 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 ...

  • Sand Plant

    Sand Plant,Sand Processing Plant The sand plant reserve came from a old stream bed, that had a 20 to 30 ft thick sand deposit in it. It was sampled and the lab testing revealed that there was less than 0.03% iron, and a few other metals (TiO2, Al2O3, MgO). The sand plant equipment length of the deposit was over a mile, so ...


  • Determination of sand content in digestate

    The biological treatment of separate collected waste becomes more and more important. The composting is still the dominant method of treating this waste, but the anaerobic alternative, the anaerobic digestion, plays an increasing part. In Germany already 15% of the whole capacity of biological treatment plants for separate collected biowaste are of anaerobic digestion (Kern, 1998), because of its ...

  • Sand making plants

    Sand Making Plant instruction Artificial sand is widely used in highway construction, crusher plant layout, etc. As the field of industry application gradually expanded, the gradual application of natural sand failed to keep pace with the various sectors of modern world development needs. In this case, ...


  • Tackling waste in the sands of the Sahara

    When gas was discovered in the mid Sahara areas of North Africa in the 1990s Andy Ive was asked by BP to help set up the water and waste infrastructure for what amounted to four small towns 600 km into the desert. No local infrastructure at all existed for the waste and water to be produced by 2-3000 workers. IVE overcame sandstorms, extreme heat, poisonous snakes and patented a novel solution to ...

  • Oil Sand - Keeping the oil flowing

    Global Water Intelligence looks at the North American oil sands industry, its use of water, and the potential for developing new processing and treatment technologies The majority of oil sands operations are limited to Alberta, Canada, where oil is found in the form of bitumen. According to the Canadian Association of Petroleum Producers (CAPP), there are 173 billion barrels (bbl) of ...

  • Rapid on‐site separation of as(III) and as(V) in waters using a disposable thiol‐modified sand cartridge

    The rapid redox transformation of arsenic (As) species in waters presents a great environmental challenge in accurate determination of its concentration and toxicity. The motivation for our study is therefore to develop a method for rapid on‐site separation of As(V) and As(III) in various aqueous matrices. We synthesized a thiol‐modified sand (T‐sand), which selectively removed As(III) but did ...

  • Magnets: A viable alternative to flotation for sand producers

    Introduction The basic rudiments of mineral beneficiation have not changed for many years. The techniques have been improved, but are still essentially the same, using either a materials weight, density, shape or magnetic susceptibility to enable separation. For removing impurities from non-metallic minerals, such as silica sand, typical methods include Flotation, Gravity and Magnetic ...

  • Innovation in Offshore Separation Process

    CLOV is a deep-sea oil production project offshore Angola. Sulzer helped to lower the cost of the floating production, storage, and offloading (FPSO) ship. There, Sulzer’s patented distributor technology and state-of-the-art pumps are brought to life by Total’s innovative wash tank process. This combination achieves significant cost savings on the FPSO design. With a processing ...

  • Well-to-Wheels Greenhouse Gas Emissions of Canadian Oil Sands

    Are greenhouse gas emissions from Canada’s oil sands higher than those from conventional oil? Apparently yes, according to a new study funded in part by the U.S. Department of Energy. It says oil from Canada’s oil sands produce greenhouse-gas emissions that average 20% more than from oil from conventional U.S. crude. The study ...

  • Separated adsorption and bacterial degradation of microcystins in GAC filtration

    For removal of microcystins from drinking water, Granular Activated Carbon (GAC) filtration has shown to be promising as it is not only an efficient adsorbent, but also can support biodegradation of microcystins, extending the lifetime of this application. In this study, a sterile and non-sterile GAC column, in addition to a sand column, was studied to distinguish the adsorption and ...

  • 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 ...

  • Vibrating Screen Separators: Maintenance and Downtime Issues

    A vibrating screen separator is a big investment for any operation and an important part of your overall process. A good screening machine will be able to reliably meet your production goals while keeping your overhead costs to a minimum. The potential for maintenance and downtime are important considerations to factor into a new ...

  • 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 ...

  • Recovery of sillimanite from beach sand of Chhatrapur, Orissa, India and its thermal treatment for refractory application

    Beach sands of Chhatrapur, Orissa, India comprise about 18% of heavy minerals, mixed with light minerals like quartz and feldspar. Sillimanite, which has refractory applications, accounts for 8% of these heavy minerals. Sillimanite was separated from garnet, monazite, zircon, rutile, ilmenite, magnetite, hematite and pseudo-rutile by combination of spiral, Wet High-Intensity Magnetic Separation ...

  • Joint estimation of hydraulic conductivities of two sand samples in a W-tube system with a bi-exponential response

    The motivation for this paper is the practical problem of interpreting bi-exponential rate-of-rise curves that are observed during many field piezometric tests. In the authors' previous study, a laboratory W-tube system of water flow through two samples of sand was introduced with an adequate mathematical model. The desired bi-exponential character of water flow was obtained by placing two ...

  • 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 ...

  • 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 ...
