  • Coating techniques for glass beads as filter media for removal of manganese from water

    Dry as well as wet coating techniques were developed to coat glass beads as filter media to remove manganese from water. For dry coating, powdered manganese oxide ore was fixed on the media surface. Wet coating was achieved by depositing synthetic manganese oxides onto the bead surface. The media were characterized by electron microscopy as well as by testing the removal of Mn2+ in a ...

  • Filtration and manganese removal

    Manganese removal through a filter bed is generally carried out and accepted by practitioners and researchers as occurring through catalytic oxidation at the surface of MnO2 coated media, although manganese passage through a coated media filter has been little investigated. To better understand the kinetics of Mn removal through a naturally coated filter, a pilot plant consisting of four filter ...

  • Effectiveness of oxidative filter materials for manganese removal from groundwater

    The experiments reported in this paper were conducted at a pilot plant consisting of filtration columns filled with oxidative filter materials. The installation was supplied with water containing manganese in concentrations ranging from 0.2 to 1.4 mg/L. The aim of the experiments was to determine the effectiveness of manganese removal on the three filter media as a function of their internal ...

  • Low-temperature effects on the removal of soluble manganese in MnOx(s)-coated media systems

    The purpose of this study was to investigate the role of low-temperature conditions in potentially impacting soluble Mn2+ removal in MnOx(s)-coated media systems. The study involved an extensive examination of water quality and process data for a 10-year period (2005–2014) from the Harwood's Mill Water Treatment Plant in Newport News, VA. Additionally, laboratory-scale shallow depth ...

  • Effect of oxygen deprivation on treatment processes in a full-scale drinking water biofilter

    Dissolved oxygen is critical for proper operation of waterworks that utilize anaerobic groundwater and rely on biofilters to remove iron, manganese and ammonium. In these biofilters, planned or inadvertent oxygen deprivation may occur for a variety of reasons. The water quality effects of oxygen deprivation on the function of drinking water biofilters, however, have not previously been reported. ...

  • Control of metal oxide fouling in reverse osmosis

    High levels of iron and manganese, along with large quantities of dissolved gases in the wells created concern for the viability of a conventional desalination design for the proposed City of Camarillo groundwater desalination facility. To identify viable pre-treatment process(es) for the control of metal oxide fouling in reverse osmosis, a 12-month pilot study was undertaken. The pilot study ...

  • From urban municipalities to polar bioremediation: the characterisation and contribution of biogenic minerals for water treatment

    Minerals of biological origin have shown significant potential for the separation of contaminants from water worldwide. This study details the contribution of biologically derived minerals to water treatment operations, with a focus on filtration media from urban municipalities and remote cold regions. The results support biofilm-embedded iron and manganese to be the building blocks of ...

  • The role of backwash in start-up of full-scale drinking water biofilters

    The purpose of backwashing during the start-up period of rapid biofilters at drinking water treatment plants differs significantly from the purpose of backwashing during normal operation. During start-up, finished water quality is secondary, detachment of microorganisms must be minimized, dust present in the original filter media must be removed and inherent inoculation of the biofilter with ...
