Someone know if there is a standard to do lab tests regarding filtration using an activated carbon column?

Which are the main parameters to take in account for this kind of tests? Only the most fine suspended solids from the water.

Yes ASTM International Committee D28 has standards. Google at http://www.astm.org and search

I know someone using modified active carbon for removing metal ions like Na, K, Mg and Ca in order to achieve disseminating the sea water in a cheap way when RO technology is still a priority of choice for industry. Another tip for application of active carbon is how to recover the active carbon when it is fully loaded by those ions.

I've found the ASTM D6586, related with a Standard Practice for the Prediction of Contaminant Adsorption on GAC in Aqueous Systems Using Rapid Small-Scale Column Tests; I think I can interpret as contaminant suspended solids and absorbable ions as mentioned in previous comment. What do you think?

Multi-media filters are often used to remove suspended solids, they need to be back washed periodically when the pressure drop is high and flow rate reduced, so a fines management process is needed for the back wash product. Activate

I am looking for a solution where will be possible to eliminate the most possible amount of suspended solids from a treated AMD, really I am not interested in remove dissolved metals or anything else. Which can be a suitable solution? Have you got detailed information about multimedia filters?

Yes there are coal based media that do not have the added cost of carbon activation.
