Hello,
I'm looking for any useful information on the options available for removal of heavy metals, specifically arsenic, copper and mercury, from an oily water discharge system.
current levels and requirements are approx. 0.4 mg/l down to 0.1 or less for arsenic and copper and 0.1 down to 0.02 mg/l for mecury. We're talking about 20kg of metal annually. dilution is not regarded as being acceptable, at least at this stage.
We've found removal systems for individual elements, but would prefer some sort of absorption bed or relatively small unit to avoid any flocculation systems etc to remove this, even it means dual beds and changing the material on a regular basis. Any suggestions as to suitable technologies would be gratefully received. Site is in Europe, but could source equipment from anywhere in the world.
Thanks

Also: There's usually a good reason why everyone does it that way
