  • Mechanisms of scale deposition and scale removal in porous media

    Calcium sulfate scaling and scale removal have been studied experimentally and theoretically in a well-defined unconsolidated porous medium. The effects of injection rate, scale concentration and temperature on the rate of scale formation and the rate of its removal are investigated. The results of the experiments are used to develop mechanistic models for the prediction of the scaling process in ...

  • 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 ...

  • Electrochemical removal of pentachlorophenol in a lab-scale platinum electrolyzer

    This study is focused on the removal of pentachlorophenol from its aqueous phase by electrochemically induced degradation with Pt electrodes. The objective of this study was to contrast the electrochemical removal of pentachlorophenol at the oxidative and the reductive potentials, and further to understand how to apply the electrochemical treatment on PCP degradation. Lab experiments were ...

  • A laboratory-scale mixed multibarrier for removal of ammonium from landfill leachate contamination

    A column-scale multibarrier, combining nitrification and ion exchange processes in a mixed configuration, was evaluated for the removal of ammonium (325 ± 60 mg N L−1) from landfill leachate contamination. Inoculating granular clinoptilolite with nitrifying bacteria resulted in a 3.2 times higher overall ammonium removal, compared with a non-inoculated ...

  • Rapid small-scale column tests for Cr(VI) removal by granular magnetite

    This study evaluates the possibility of using magnetite as an adsorbent for the removal of Cr(VI) in a bed column setup under continuous flow conditions. For this purpose, granular magnetite was synthesized on a large scale and tested in both batch and rapid small-scale column experiments using reliable conditions of drinking water treatment. Column tests, which were designed to scale-down ...

  • Comparing methods to remove emerging contaminants and disinfection by-product precursors at pilot scale

    The removal of selected pharmaceuticals and personal care products, atrazine, and disinfection by-product precursors, was evaluated during a pilot-scale study conducted at the Bollman Water Treatment Plant in Concord, California, USA. Treatment alternatives included ozonation followed by biologically active filtration (BAF), and nanofiltration. Both technologies exhibited excellent broad-spectrum ...

  • Interactions between ammonia, iron and manganese removal using pilot-scale biofilters

    Pilot-scale biofilters treated with real groundwater were established to systemically investigate the interactions between ammonia, iron and manganese removal. When both of ammonia and manganese in influent were about 1 mg/L, they were quickly removed; but when manganese was above 3 mg/L, ammonia removal was affected significantly. When total iron was above 5 mg/L, the oxidization rate of ...

  • Pilot-scale study of powdered activated carbon recirculation for micropollutant removal

    Adsorption onto powdered activated carbon (PAC) is a promising technique for the removal of organic micropollutants (OMPs) from treated wastewater. To enhance the adsorption efficiency, PAC is recycled back into the adsorption stage. This technique was examined in pilot scale in comparison to a reference without recirculation. Coagulation with Fe3+ was carried out simultaneously to adsorption. ...

  • Biological iron and manganese removal, pilot and full scale applications

    Both manganese and iron are found in surface and ground waters at varying concentration levels. When present even at low concentrations they can be linked to the following problems: discolouration, turbidity and taste problems or form slime and iron noxide or manganese dioxide accumulations in pipes. Both metals promote the growth of certain types of chlorine tolerant micro-organisms in water ...

  • A Struvite Control and Phosphorus Removal Process for Centrate: Full-Scale Testing

    ABSTRACTThe North End Water Pollution Control Centre (NEWPCC) in Manitoba, Canada serves a population of approximately 380,000. The dry weather flow to the NEWPCC is approximately 175 ML/d (46 MGD). The plant uses anaerobic digestion and centrifuge dewatering in its solids treatment train. The centrate stream comprises approximately 20 percent of the plant’s phosphorus load. The plant suffers ...

  • Removal of aqueous phenol using immobilized enzymes in a bench scale and pilot scale three-phase fluidized bed reactor

    The main objective of this work was to investigate the removal of aqueous phenol using immobilized enzymes in both bench scale and pilot scale three-phase fluidized bed reactors. The enzyme used in this application was a fungal tyrosinase [E.C. 1.14.18.1] immobilized in a system of chitosan and alginate. The immobilization matrix consisted of a chitosan matrix cross-linked with glutaraldehyde ...
