Concurrent arsenic, fluoride, and hydrated silica removal from deep well water by electrocoagulation: Comparison of sacrificial anodes (Al, Fe, and Al-Fe).

Some studies have reported the removal of As (As) and fluoride (F) using different sacrificial anodes; however, they have been tested with a synthetic solution in a batch system without hydrated silica (SiO) interaction. Due to the above, concurrent removal of As, F, and SiO from natural deep well water was evaluated (initial concentration: 35.5 μg L As, 1.

Removal of fluoride and hydrated silica from underground water by electrocoagulation in a flow channel reactor.

This paper concerns simultaneous removal of fluoride and hydrated silica from groundwater (4.08 mg L fluoride, 90 mg L hydrated silica, 50 mg L sulfate, 0.23 mg L phosphate, pH 7.
