• WM Accepted effect: P2(water filter): Removal of certain organic chemicals(eg
hydrocarbon related) & non organic(eg chlorine) as absorption filter Granular
Activated Carbon(GAC)/Pulverized Activated Carbon(PAC). Often a part of various
filter system, Grass roots or biochar movement NGO group promotes use of biochar
for water filter by usually offered by “non-mainstream” type or DIY focused
suppliers(Wesionline, Nextchar, Terra-Char+),
• Activated Carbon is a major part in std process of mixed hydrocarbon & other
contaminant removal from water, or commercialized for general water filter. Some of
larger producers of solid wood biochar might be selling “top grades” to some of
“fringe” group high price bidders(Haycarb, Fujian Yuanli, Carbon activated corp+):
they don’t value coal or nonsolid wood biomass based ones.
• WM (only occasionally) disputed effect: O2(Hydroxyl production): Waste water
treatment as decomposing element in addition to filtering effect of biochar:
(Carbon-terra eu.+), P2(Bioenhancing effect): Some companies claim high grade
solid wood biochar based filter actually increase “vitalization” effect of water:
(Hitousui, N-t-c jp+): This seem to have wide range of degree depended on raw
material for biochar and processing method.
