MIT engineers make filters from tree branches to purify ingesting water

Prototypes examined in India present promise as a low-cost, pure filtration possibility.

The interiors of nonflowering timber equivalent to pine and ginkgo include sapwood lined with straw-like conduits generally known as xylem, which draw water up via a tree’s trunk and branches. Xylem conduits are interconnected through skinny membranes that act as pure sieves, filtering out bubbles from water and sap.

MIT engineers have been investigating sapwood’s pure filtering capacity, and have beforehand fabricated easy filters from peeled cross-sections of sapwood branches, demonstrating that the low-tech design successfully filters micro organism.
