  • 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 ...

  • The on-site feasibility study of iron and manganese removal from groundwater by hollow-fiber microfiltration

    The aim of this research was to investigate the removal of iron and manganese from groundwater by aeration, chlorine oxidation and microfiltration (MF). Pilot-scale experiments were performed at the Chang-Hua Water Treatment Plant in Taiwan. The raw waters contained soluble iron (0.4 mg/L) and manganese (0.5 mg/L) which were oxidized by chlorine and then filtered by hollow-fiber PTFE-MF. The ...

  • Project profile - Village of Corona, NM iron and manganese reduction

    Background In the fall of 2008, AdEdge was selected by Village of Corona, NM to design, manufacture, and startup a water treatment system for the removal of iron and manganese. The water system that serves approximately 100 connections at Corona was plagued by high iron and manganese in the main water supply with iron from 0.26 – 2.8 mg/L and manganese levels from 0.094 - 0.17 ...

  • Competitive mechanism of ammonia, iron and manganese for dissolved oxygen using pilot-scale biofilter at different dissolved oxygen concentrations

    In this study, the competitive mechanism of ammonia, iron and manganese for dissolved oxygen (DO) in a biofilter was investigated, and a new start-up method of a biofilter for ammonia, iron and manganese removal was approved, which can effectively shorten the start-up period from 3–4 months to 51 days. The results demonstrated that when DO was sufficient (about 8 mg · L−1), ammonia, iron and ...

  • Reverse osmosis and removal of minerals from drinking water

    Reverse Osmosis will generally remove salt, manganese, iron, flouride, lead, and calcium (Binnie et. al., 2002).  Most mineral constituents of water are physically larger than water molecules and they are trapped by the semi-permeable membrane and removed from drinking water when filtered through a RO (AllAboutWater.org, 2004).  Meanwhile, consumers are concerned about the removal of ...
