Using wood to filter and purify wastewater

[Deep Sea Diver]

Folks are finding more and more ways that trees can be valuable to human existence.

In this recent study MIT engineers used pine and ginkgo (gymnosperm sapwood) xylem tissue for wastewater water filtration.... and then took the idea to India and used native trees to try it out there to good effect.

The prototype filtered at the rate of one liter/hour, however the possibilities for expansion are very interesting.

Trees or their products in filtration systems- natural or man made- ha been a practice for centuries, but this is particularly interesting. I'll have to read it through and see what sorts of restrictions on species it might bring up.
I enjoy pushing my survivalist limits while camping, and have built improvised filtration systems with charcoal from the fire and sand from wherever. This could be something that might make a lighter more portable filtration system for emergencies.
