  • 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 ...

  • 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. ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...

  • Changing the Rules with Mass Detection

    How simplified detectors can provide mass data for every analytical run and speed up method development With access to multiple mass spectrometry systems of varying degrees of sophistication, Davy Guillarme (University of Geneva, Switzerland) wasn’t actively looking for new mass detection solutions. Nevertheless, the Waters ACQUITY QDa mass detector caught his eye. Why? Because it opens a ...

  • The Clog Blog

    Clogging and over pressuring are definitely problematic for Liquid Chromatography columns. Back in 2005 John Dolan’s sage advice to chromatographers to make an LC column last forever was simple, “Never open the box!” As John pointed out, this is not practical and I have to agree. But as an LC column manufacturer I have seen remarks from customers regarding clogging as though it ...

  • Optimisation of micro-processes for shear-assisted solid–liquid separation in a rotatory batch flow vortex reactor

    This paper reports the study of micro-processes in a novel pre-treatment technique using a pellet forming batch flow vortex reactor of cylindrical shape that consists of axially revolving rotor plates between fixed stator plates. The suspension was first mixed with high molecular weight synthetic polymers by stirring for approximately 50 seconds and then agitated for 20 minutes. The process ...

  • 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 ...

  • 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. ...

  • Separation principle of decanting centrifuge

    KOSUN DC series decanting centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and ...


  • 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 ...

  • 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 ...

  • Towards municipal solid waste source separation at the household level in Accra, Ghana

    Municipal solid waste source separation at the household level has been endorsed as the way forward by all stakeholders in the waste management sector in Ghana. The study using waste stream analyses and laboratory investigations assesses the feasibility of this intervention in the Accra Metropolitan Area which has been divided into three income zones. The mean waste percentage composition was ...

  • Robust corona-electrostatic separation method for solid waste recycling

    The objective was to reduce variation in the outcome of a corona-electrostatic separation process for solid waste recycling by finding operating conditions (high-voltage level, roll speed, splitter position) under which uncontrollable variation in 'noise factors' (ambient humidity, metal content in the feed) has minimal impact on the quantity and the quality of the recovered products. The samples ...

  • Anaerobic fermentation of organic solid wastes: volatile fatty acid production and separation

    Anaerobic fermentation of organic municipal solid waste was investigated using a leach-bed reactor (LBR) to assess the volatile fatty acid (VFA) production efficiency. The leachate recycle rate in the LBR affected the VFA composition of the leachate. A six-fold increase in the recycle rate resulted in an increase of the acetic acid fraction of leachate from 24.7 to 43.0%. The separation ...

  • Phosphorus distribution in untreated and composted solid fractions from slurry separation

    Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

  • What Are the Benefits of Using a Mechanical Vibrating Separator for Bulk Solids?

    Mechanical vibrating separators are one of three main types of industrial screening machines, along with rectangular and circular screeners. While mechanical separators are generally considered to be at the lower end of the technological spectrum, they offer several advantages over other types of machines in certain bulk solid screening applications. Advantage #1: Cost With their ...

  • Fundamentals of Multi-Sensor Separation Systems

    This paper gives an overview of the research at the Delft University of Technology in the field of automatic quality control and sorting systems, which are applied for solid bulk materials in the recycling industry. From theory it is known that a simultaneous detection of several features with sensors of different detection principles improves the quality of the classification dramatically. ...

  • Source Separated MSW Composting in the US

    MUNICIPAL solid waste composting projects are being launched based on residential separation of the compostable stream from recyclables and trash - quite widespread in Europe and increasingly in Canada. One trend - typically in cities and suburban communities - is to add source separated residential organics to existing yard trimmings collection programs. Composting facilities permitted to ...

  • National Separation Strategy for MSW in Finland

    Abstract A spreadsheet model, TASAR, was developed for analysing national separation strategies of municipal solid waste (MSW) in Finland. The model was used to answer the following question: What kind of a strategy is needed to attain the recovery rate target of 70 %wt set for MSW in Finland? TASAR proved to be a useful planning tool. Firstly, source separation was studied resulting in ...
