Enhanced As(III) removal with permanganate oxidation, ferric chloride precipitation and sand filtration as pretreatment of ultrafiltration
... and direct sand filtration as pretreatment before ultrafiltration. The pretreatment effectively facilitated As(III) removal and residual arsenic was below 10 µg/L for membrane effluent. Sand filters exhibit good potential for removing ferric precipitates with adsorbed arsenic, and membran ...

Characterization and treatment of wastewater produced during the hydro-metallurgical extraction of germanium from fly ash
... produced during the hydrometallurgical recovery of germanium (Ge) from fly ash. The main metals causing reasons for environmental concern were arsenic (As), nickel (Ni) and antimony (Sb). Precipitation using calcium hydroxide (hydrated lime) was the most efficient method for treating wastewater ...
