  • A Comparison of Methods to Determine the Particle Size

    There currently exist a multitude of techniques to determine particle size distributions. However, in assessing the particle size distribution (PSD) of solids in a stormwater sample, the number of suitable techniques is considerably reduced due to the limited quantity of solids in a typical stormwater sample. The electrical sensing zone method (ESZ), which utilizes the Coulter Principle, and ...


  • An overview of micron-ranged particle sizing techniques

    Given the wide range of particle sizing technologies and instrumentation on the market, the choice of measurement technique can be daunting, especially if one is unfamiliar with the options available. Once introduced and familiar with an individual technique, it can be easy to continue to choose it by default. While this is certainly understandable, it may prove a disservice when the technique is ...

  • European On-Line Particle Mass Spectrometry

    An international workshop on European On-line Particle Mass Spectrometry (PMS) was held 29th-30th of November 2005 at the JRC in Ispra, Italy. The main goals of the Workshop were: 1) To get together all European scientists involved in the field of PMS 2) To review the latest scientific progress on the field of PMS, with particular emphasis on:a. New instrumentationsb. Data analysisc. ...


  • Impact of heating method on the flocculation process using thermosensitive polymer

     Flocculation process based on water soluble polymers as flocculating agents is still intensively researched nowadays, despite the introduction of these materials about fifty years ago. There is a need to gain the full control of this process in order to obtain high efficiency and strictly define products. For that purpose new solutions are proposed like stimuli-responsive macromolecules. In ...

  • Kinetics of lead and copper removal from oil-field brine by potential sorption

    The present study investigates the kinetics of lead and copper removal from oil-field brine by potential sorption. A population balance equation, coupled with a mass balance equation, was used in the estimation of kinetic parameters. Metal removal was performed by potential sorption of lead and copper through CaCO3 precipitates induced by the reaction of Na2CO3 and ...

  • Inhibitors for CaCo3-scaling in reverse osmosis-plants - influence of suspended matter on membrane clogging

    Abstract Calcium carbonate (CaCO3) is the most common source of mineral scaling in reverse osmosis plants, and it is a standard approach to add so-called anti-scalants to avoid membrane blocking. Although anti-scalants are used for many years, it remains a challenge to determine the most effective anti-scalant and its necessary dosage for a given water. The reason why, is the ...
