  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • The danger of arsenic in water and the technology to end with it

    AZUD has developed a technology that saves lives: the water purifiers plants AZUD DW DU are the perfect solution for arsenic removal using ultrafiltration membranes. In Latin America, AZUD DW DW supplies drinking water to decentralized villages that used to consume arsenic contaminated water. In ihe last two decades, in some countries of Latin America, people have consumed double the arsenic ...

  • Optimisation of sugar cane activated carbon for arsenic(V) and arsenic(III) removal from water

    This paper addresses the development of low-cost adsorbents for removal of arsenic from water in support of mitigation programmes in low and middle income countries. Activated carbon (AC) is a well established water treatment technology, but has high cost and low selectivity in respect of arsenic. AC made from agricultural by-products is a low-cost alternative to coal-based AC. In this study, ...

  • A performance assessment of arsenic-iron removal plants in the Manikganj District of Bangladesh

    In Bangladesh, arsenic contamination of groundwater, microbial contamination of surface water and seasonally variable rainfall make reliable access to acceptable quality drinking water a challenge. Arsenic-iron removal plants (AIRPs) are a relatively inexpensive way of removing arsenic from groundwater for access to safer drinking water. This study evaluated the performance of 21 (of 105) AIRPs ...

  • Project profile - Foxxtown Apartments Sudlersville, Maryland arsenic, iron & manganese removal

    Background AdEdge Technologies Inc. (AdEdge) was selected in 2006 by McCrone Engineers and the awarded contractor, Maryland Construction to design, build, and install a full scale AD26GS+ arsenic, iron, and manganese treatment system for their customer Foxxtown Apartments in Sudlersville, Maryland to meet the new EPA arsenic standard. The treatment system was based on the design ...

  • Subsurface iron and arsenic removal: low-cost technology for community-based water supply in Bangladesh

    The principle of subsurface or in situ iron and arsenic removal is that aerated water is periodically injected into an anoxic aquifer through a tube well, displacing groundwater containing Fe(II). An oxidation zone is created around the tube well where Fe(II) is oxidised. The freshly formed iron hydroxide surfaces provide new sorption sites for soluble Fe(II) and arsenic. The system's efficiency ...

  • Characteristics of arsenate removal from water by metal-organic frameworks (MOFs)

    Contamination of arsenic in groundwater and surface water occurs frequently across the globe, requiring an effective purification technology. Among the common technologies, the adsorption method is widely used for the merits of low cost and easy operation. Nevertheless, the development of efficient adsorbents remains one of the central challenges in this field. In this article, one kind of ...
