[Stoves] research on activated carbon for water filters for the victims of disasters

[Richard Stanley]

Joshua, 

Its always good to hear from you. 

Regarding your request for creating activated carbon filter for purifying water, I am taking the liberty of passing this on to the stoves and the biochar online discussion groups, as these groups contain a host of really sound  technical resource persons with year os experience from all over the globe.
 
This seems to be a whole new application of/ rationale for  biochar eh ? 

Anybody  ?
Kind regards, 

Richard Stanley

But now i cannot remember the right procedure anymore. This i would like to seek your help on how to make it in a post disaster situation. I guess, there will be a lot of wood debri of timber, wood stick plus... pieces of metal and other parts of the house.
