GC Filtral-AS

activated alumina for arsenic removal

GC Filtral-AS is a granular activated alumina designed with a proprietary additive for the removal of arsenic from water. the GC FiltralAS is typically able to remove two to three times more arsenic than standard activated alumina.

Arsenic commonly occurs in two forms, as (V) (arsenate) and As(III) (arsenite). Maximum arsenic capacity is achieved when dealing with As (V). GC FILTRAL AS's capacity for As(III) adsorption is about %40 its capacity for As (V). Oxidation is recommended to assist with As(III) removal, when possible. Simple chlorination will oxidize As(III) to As(V) allowing complete removal.

GC FILTRAL-AS can be effective at a wide range of pH levels depending on the competing ions present. Where high levels of silica are present, along with a pH level higher than 7.0, an adjustment may be necessary for optimum results.

The GC Filtral AS is available for sale in bulk or installed in any of our liquid-phase treatment units. These filters come complete with intrnal plumbing and are ready for installation.
