Arsenic removal from high-arsenic water by enhanced coagulation with ferric ions and coarse calcite.
Arsenic removal from high-arsenic water in a mine drainage system has been studied through an enhanced coagulation process with ferric ions and coarse calcite (38-74 microm) in this work. The experimental results have shown that arsenic-borne coagulates produced by coagulation with ferric ions alone were very fine, so micro-filtration (membrane as filter medium) was needed to remove the coagula...
متن کاملNitrate removal from water using alum and ferric chloride: A comparative study of alum and ferric chloride efficiency
Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. Methods: In this research...
متن کاملArsenic Removal from Groundwater using Ferric
Arsenic is a carcinogenic metalloid that is currently regulated in drinking water. The levels of arsenic in finished water in an existing water treatment plant are exceeding the current regulation of 10 μg/L. One of the available technologies for arsenic removal from groundwater is adsorption onto coagulated flocs and in this field, ferric chloride is the most commonly used coagulant for arseni...
متن کاملArsenic removal by coagulation
he current 50-μg/L maximum contaminant level (MCL) for arsenic in drinking water was first set by the US Public Health Service in 1942 and was adopted by the US Environmental Protection Agency (USEPA) in 1975.1 The standard was based primarily on toxic effects resulting from short-term or acute exposure to arsenic.2 Subsequent investigations have linked arsenic in drinking water with skin cance...
