3-phase liquid-solid separation Articles

  • 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 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Liquid-phase non-thermal plasma-prepared N-doped TiO2 for azo dye degradation with the catalyst separation system by ceramic membranes

    This study strived to improve the photocatalytic activity by using liquid-phase non-thermal plasma (LPNTP) technology for preparing N-doping TiO2 as well as to separate/recover the N-dope TiO2 particles by using ceramic ultrafiltration membrane process. The yellow color N-doped TiO2 photocatalysts, obtained through the LPNTP process, were characterized with UV–Vis spectroscopy, X-ray diffraction ...

  • 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 ...

  • 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 ...

  • Novel mixed-mode stationary phases for chromatographic separation of complex mixtures of decomposed lignin

    Abstract Electrochemical degradation of lignin results in a large number of unknown products, formed by both oxidative and reductive decomposition pathways, which have previously been studied by direct mass spectrometry experiments without prior liquid chromatography separation, revealing the presence of many isobaric molecules. In this study, novel phosphonium-based ionic liquid stationary ...

  • Visualized study on the interaction between single bubbles and curved solid surface in flotation separation process

    The present study has been devoted to bubble–curved solid surface interaction in water, which is critical to the separation of suspended particles by air flotation. For this purpose, two particular stages of the interaction (collision and attachment) have been examined visually using high-speed photography in a laboratory-scale flotation column. The effects of the surface material and ...

  • Supported liquid membrane system for Cr(III) separation from Cr(III)/Cr(VI) mixtures

    This paper presents the results of analyses of the chromium(III) transport process from mixtures of Cr(III)/Cr(VI) ions using supported liquid membranes (SLM), in which dinonylnaphthalene sulfonic acid (DNNSA) and di(2-ethylhexyl) phosphoric acid (D2EHPA) were used as carriers. In both cases the membrane worked as a selective barrier for Cr(VI) ions. The increase in both the time of Cr(VI) ...

  • Separation efficiency of a hydrodynamic separator using a 3D computational fluid dynamics multiscale approach

    The aim of this study is to investigate the use of computational fluid dynamics (CFD) to predict the solid separation efficiency of a hydrodynamic separator. The numerical difficulty concerns the discretization of the geometry to simulate both the global behavior and the local phenomena that occur near the screen. In this context, a CFD multiscale approach was used: a global model (at the scale ...
