  • 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 ...

  • 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 ...

  • 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. ...

  • Evaluation of PFCA removal by SAT using a pilot-scale reactor

    Wastewater reuse using soil aquifer treatment (SAT) is a rational and realistic solution in countries and regions with limited freshwater resources. The behaviour and removal of perfluoroalkyl carboxylic acids (PFCAs) under long hydraulic retention times (HRTs) in SAT may warrant further investigation. In this study, actual treated effluent from a wastewater treatment plant (WWTP) was ...

  • 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 ...

  • 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 ...

  • 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 ...

  • DOC Removal by MIEX® Process - Scaling-Up & Other Development Issues

    Natural organic matter (NOM) is one of the main parameters which affects water quality and performance of water treatment processes. Current processes including coagulation, oxidation, filtration and adsorption are at times inadequate or uneconomic. ...

  • Influence of nitrite on the removal of Mn(II) using pilot-scale biofilters

    Two pilot-scale biofilters were used to systematically investigate the influence of nitrite on biological Mn(II) removal. Gibbs free energy change (ΔG) of the redox reaction between MnO2 and NO2– was 122.28 kJ mol–1 in 298 K, suggesting that MnO2 could not react with NO2–. When nitrite in the influent was increased from 0.05 to 0.5 ...

  • 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 ...

  • Laboratory- and full-scale studies on the removal of pharmaceuticals in an aerated constructed wetland: effects of aeration and hydraulic retention time on the removal efficiency and assessment of the aquatic risk

    Pharmaceutical residues in wastewater pose a challenge to wastewater treatment technologies. Constructed wetlands (CWs) are common wastewater treatment systems in rural areas and they discharge often in small water courses in which the ecology can be adversely affected by the discharged pharmaceuticals. Hence, there is a need for studies aiming to improve the removal of pharmaceuticals in CWs. ...

  • Removal of DOM and AOC in a full-scale advanced water treatment plant: effects of operational periods of BAC filters

    Water utilities in Japan want to reduce residual chlorine levels so as to reduce disinfection byproducts and the chlorine smell, but bacterial regrowth is a concern. In advanced water treatment plants using ozonation and biological activated carbon (BAC), BAC plays the most important role in reducing assimilable organic carbon (AOC). Therefore, we analyzed the removal of dissolved organic matter ...
