Dimethyl Arsenate (DMA) Organoarsenic Wastewater Treatment


Does anyone here have any experience in treating Dimethyl arsenate from an effluent stream? Concentration: ~ 1000 - 1500 ppb, has a bunch of other heavy metals as well. Like is there an effective (in terms of kinetics) way to first reduce and then demethylate MAs(V) to As(III) (reducing agents, bacteria?) ?
Then, perhaps it could be oxidized to As(V) and later precipitated with FeCl2.

Or would a CASP/MBR system work for this effluent stream ?

Any thoughts?

Thank you in advance for your help.
