How to purify water
1. Vortex Generator
Watreco's water treatement products use the patented Vortex Generator and the technology platform VPT (Vortex Process Technology) to create energy-efficient, low-cost solutions for several water treatment problems. The system essentially works by...

2. Aquaporin membrane technology
The Aquaporin company is focusing on mimicking the ability of lipid bilayers in biological cells to transport water back and forth across membranes by way of membrane channel proteins called aquaporins. Aquaporins can facilitate this transport wh...
3. Algal turf scrubber
"Algal turf scrubbers are field-sized, water-treatment systems that can extract excess nutrients from streams, canals, and lakes polluted by agricultural, domestic, and some industrial runoff. They use sunlight as their principal source of e...
4. Biolytix® water filter
The Biolytix® System is a compact waste treatment system that converts raw sewage, wastewater, and food waste into high quality irrigation water on site. The Biolytix® system removes solid wastes from wastewater immediately. Then selected...
5. Bubble net system to catch fish
A system comprising bubble-making chambers, ballast, and conducting and floating tubes is operated from a boat and used to form an underwater wall of bubbles that enables schools of fish to be trapped and subsequently caught by means...
6. Air-trapping coating for ships, submarines
Researchers from the Nanoprobe Laboratory for Bio- & Nanotechnology and Biomimetics, The Ohio State University, are developing a biomimetic coating for use on ships and submersible aquatic vehicles. The purpose of their research was to mimic t...
7. PAX Scientific; PAX Water Technologies; PAX Streamline; PAX Mixer; PAX Fan
Jay Harman began his quest to understand vortical fluid dynamics. The result: a new principle for generating flow that has applications ranging from pump to impellers, fans to boats. All arenas offer improved energy efficiency, smaller devices, an...
8. Capturing prey above the water's surface: archer fish
"Further animal artefacts that resemble tools include the woodpecker's anvil, a tree stump with a suitable wedgelike cavity to hold cones, the use of a water jet to shoot down prey by the archer fish (Trichogaster jaculatrix), and the Australian b...
9. Body temperature regulated in hot environment: African camels
"When African camels (Camelus dromedarius) do not get enough water, their body temperature's amplitude (the difference between its highest and lowest values) increases from 3.6°F (2°C) to as much as 10.8°F (6°C)." (Shuker 2001:91)
10. Round shape reduces water loss: pebble plants
"Pebble plants grow in the stonier patches of the same [Namib] [D]esert. They survive by living partly underground. Their leaves have been reduced to a single pair, fat, round and succulent, with just a groove between them from which, in the right...
