Abstract
PURPOSE: For effective utilization of underground water or earth-heated water, arsenic and silica containing water is adsorbed by anion exchange body, desorbed by basic material and separated for simultaneous arsenic and silica removal.
CONSTITUTION: An anion exchanging body is used to adsorb arsenate ion and silicate ion in arsenic and silica containing water such as underground water or earth- heated water. The anion exchanging body so used is contacted with aqueous basic solution such as sodium hydroxide to cause the arsenate and silicate ions to be separated from the anion exchanging body as salts of basic material. Water containing such salts of separated arsenate and silicated is added with acid to transform silicate to silica which is separated by filteration. Arsenic is returned to underground without being blocked by silica deposition.
