From rice hulls to water filters
"By converting rice hulls to a stable carbon, you can activate it"
"Activated carbon is like a sponge. If you have a Brita filter in your home or pitcher based systems, what's in there is activated carbon, to pull out the chlorine and take out the odour, and a lot of the things that affect the taste of the water. [We added] an additional capability to that basic carbon structure, to be able to pull dissolved metals out."
