  • Competitive removal of DOM and bromide in raw waters by MIEX and iron coagulation

    Dissolved organic matter (DOM) and bromide as principal precursors to halogenated disinfection byproducts (DBPs) have potential risks on the safety of drinking water after disinfection. Removal of DOM and bromide in raw water from two different waterworks using magnetic ion exchange resin (MIEX), ferric coagulation and their combination was investigated. Results showed that as MIEX dose ...

  • One process removes arsenic & iron from water in small Utah town

    The Safe Drinking Water Act brought with it tough arsenic compliance standards, forcing cities large and small to comply with a maximum contaminant level of 10 parts per billion (ppb) or face stiff fines and even the potential shutdown of wells. Smaller towns such as Cannonville, Utah, face the most difficult challenge, due to manpower and budget constraints. Cannonville turned to Filtronics, ...

  • Iron-based sorption materials for the removal of antimony from water

    The objective of this work was to verify the sorption properties of granular filter materials (GEH, Bayoxide E33, CFH12) during the process of removing antimony from water. Pilot tests showed that the use of iron-based sorption materials could possibly decrease the antimony content in water to the values limited for drinking water. At an average concentration of antimony in raw water of 58.3 ...

  • 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 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 ...

  • Distribution of iron in activated carbon composites: assessment of arsenic removal behavior

    The main objectives of this study were to evaluate the effectiveness of using iron impregnated granular activated carbon (AC) to remove arsenic from water and to assess the partitioning behavior of arsenic under a variety of conditions. Iron impregnated granular activated carbon (AC-Fe) composites were prepared with different ferric (Fe+3) concentrations, ranging from 0.09 to 3.0 M. These ...
