purify water
11. Red magroves purify salt water.
Osmosis: movement of water across a barrier from areas of low solute concentrations to high solute concentrations (passive transport). Reverse osmosis: pushes solutes across a barrier from areas of high solute concentration to low solute concentra...

12. Baleen Filters water filters
The Baleen filter is a highly efficient, non-pressurized self-cleaning separation technology that offers reliable, trouble-free filtration to 25 microns without chemical assistance. Therefore there are o...
13. BioHaven® floating islands
Floating Island International's BioHaven® Technology mimics how natural wetlands and natural floating islands filter sediments and nutrients out of surface water. However, these islands go a step further by creating a concentrated wetland effe...
15. Habitat regulates water flows: peatlands
"Peatlands are of particular interest to water resource managers because they occur extensively in the headwater areas of many streams and rivers. Peatlands can have large impacts on the quantity and quality of the receiving waters (e.g. Brooks 19...
16. Capillary Faucets
Similar to the roots of a tree, capillary tubes carry water up a few centimeters. They then create droplets by recombining those tubes so the meniscus' touch. This is derived from reverse-engineering how water gets into a coconut.Stair-stepp...
17. Leaves gather water: geophytes
"In the semidesert of Namaqualand and adjacent regions of the former Cape Province, South Africa, there occurs an assemblage of geophytes belonging to eight monocot families and some Oxalis species that exhibit special morphological adaptations of...
18. Fungal skin prevents water loss: lichens
"Others [lichens] develop minuscule branches and grow into dense curling thickets a few inches high. Their outer skin is formed by the compacted threads of the fungi and is sufficiently impermeable to prevent the loss of water from the partnership...
19. Interaction helps retain water: forests
"The results clearly show that neither maize nor grasses can duplicate the services of the original tropical forest. With its two hundred plant species, the forest lets virtually none of its soil or water escape and sustains a lush productivity ye...
20. Skin protects from water loss: desert lark
"Adjustments of lipid ratios to favor ceramides over free fatty acids and sterols have also been shown to correlate with reductions of TEWL [transepidermal water loss] in desert larks (Haugen et al., 2003a,b). The comparatively higher ratios of ce...
