Directory of water purification technologies and resources, especially as they involved renewable energy sources for their power.

Technologies

• Multi Solaqua draws on the sun to provide safe drinking water - The Solaqua is a nifty portable device that uses the sun's rays to purify contaminated water. Through innovative use of readily available materials, it carries, disinfects and stores water, providing a safe, environmentally sustainable source of water for rural communities. (GizMag; June 3, 2009)
  

• Watreco Vortex Generator - Building on nature’s own principles, Vortex Process Technology (VPT) used in the Vortex generator, builds on water’s own natural movement. The Vortex generator sets the water in a considerable swirl that changes its internal properties, purifying the water. "In Harmony with Nature" PDF (Watreco; Sept 14, 2008)
  

• Water Companies Taking Cue From Nature - When it comes to water technology, nature appears poised to become a major player. Aquaporins sit inside channels in biological cells where water, salts and solids pour in, the aquaporin flips over, ejecting the impurities and allowing fresh water to pass through the cell. (GreenTech Media; Sept. 10, 2008)
  

• Mobile MaxPure solar-powered water purification system set for Iraq duty - Created by WorldWater & Solar Technologies Corp, the stand-alone Mobile Max Pure® unit 7-foot cube opens up at the press of a button to reveal a solar array that can deliver around 3.2 kw of electricity, which combine with the company’s patented AquaMax controls to pump out and purify over 30,000 gallons of water everyday. It can be powered by solar power alone or in combination with an optional back-up generator. (EcoFriend; June 23, 2008)
  

• METROPOLIS NEXT GENERATION 2008 Winner Announced! - This year’s $10,000 prize was awarded to San Francisco based architect and CCA professor Eric Olsen for a "Solar Water Disinfecting Tarpaulin" that promises to provide portable and potable water anywhere that it is needed. (Inhabitat; May 5, 2008)
  

• Forward osmosis filtration system - HTI have developed a forward osmosis membrane that allows water to pass through, yet blocks very small contaminants. This allows a pure drink to be created from highly turbid and toxic supply waters, even sea water. It is a passive system which harnesses the osmotic potential created by sugars and electrolytes, producing a dilute sports drink, not simply water. (GizMag; Oct. 15, 2007)
  

• Difinitive Energy - AquaClean™ processes contaminated water with an electric arc (plasma) to produce clean, potable water which spontaneously creates a high energy, non-polluting, sustainable fuel (AquaLene®). The fuel is claimed to produce 3x more energy than is required to maintain the arc by powering a generator in a closed-loop process.
  

• Cleaning Up Water with Nanomagnets - It may seem an unlikely way to clean up drinking water, but scientists at Rice University, in Houston, have found that nanoparticles of rust can be used to remove arsenic with a simple wave of a magnet. (MIT Technology Review; Nov. 13, 2006) [See also Proton Cell and water purification]
  

• AquaStar - Portable Ultraviolet C-band Water Purifier can safely and quickly treat a liter of water in about a minute, using a pair of standard camera batteries to generate ionizing radiation that quickly and effectively disrupts the cellular chemistry of all known pathogens.

• Ozone Generators and Advanced Oxidation Processes - Spartan Environmental Technologies supplies ozone generators and other advanced oxidation processes for industrial and municipal water and wastewater treatment applications such as disinfection and for the removal of color, taste, odor, iron, manganese, COD, TOC and specific organic compounds. These processes make water safe to drink, recycle or discharge into the environment. Ozone is generated on site and after use decomposes to oxygen. This eliminates the need to store chemicals on site and does not introduce toxic chemicals into the water.

• Water Purification via Nano-Gold - Gold spheres, measuring 15 atoms in diameter, mixed with Palladium, and acting as a detergent, hold promise for cleaning up toxic waste more inexpensively and much faster than present methods. (Smithsonian Magazine; Oct. 2007)
  

• New Plastic to Cut CO2 Emissions and Purify Water - Scientists have created a plastic material that mimics pores found in plants and is exceptionally efficient. It can separate carbon dioxide from natural gas a few hundred times faster than current plastic membranes. (Slashdot; Oct. 15, 2007)
  

• Aqua Sun International solar water purification - Solar powered portable water purification system is capable of purifying 100 gallons/day on solar power. Distributed by First Water, Inc.
  

• WorldWater & Power to Introduce New Mobile Solar Power Unit - MobileMaxPure™ tows into a disaster areas to provide portable electricity, water purification, and telecommunications. With the flip of a switch, 15 solar panels automatically unfold to create a 12x18 foot photovoltaic array. (Renewable Energy Access: Mar. 21, 2006)
  

• Ray of light for water industry - University of Aberdeen scientists developing new technology that uses sunlight to treat dirty water and create electricity simultaneously. Three industrial partners develop novel technology for breaking up pollutants found in all types of water supplies. (PhysOrg; UK; April 28, 2005) (Renewable Energy Access; May 3, 2005)

• Solar Mobile Critical Response Water Unit Sent to Mississippi - WorldWater & Power Corp., developers of proprietary high-powered solar technology, is sending its trailer-mounted, solar-powered electrical water pumping and purification system to help the relief efforts for hurricane victims in the devastated Gulf Coast area. (PrimeZone; Oct. 12, 2005)
  

• Zip Project - Zero Impact Platform project was created to handle waste cycle and water cycle management with clean, renewable technologies available, as well as to support research and development into the same. (PESWiki; Aug. 5, 2005)

• Invention Set to Revolutionise Sewage Treatment - Kenya Medical Research Institute (KEMRI) has unveiled a simple aerobic sewage treatment plant that recycles water, odor-free, that they say is certified fit for human consumption. (AllAfrica.com; June 19, 2006)
  

Dean Kamen

• Segway creator unveils his next act - Inventor Dean Kamen wants to put entrepreneurs to work bringing water and electricity to the world's poor. 1 kW generator uses anything that burns, including cow dung. Water purifier makes 1,000 liters of water per day. (CNN; Feb. 16, 2006) (See Slashdot discussion)

• New Earth Systems CentrO3fier - Modular treatment system highly effective at removing wide range of contaminants including ammonia, arsenic, heavy metals, toxic organics, phosphates, and many others. Second generation completed; preparing for market.
  

• EnergyQuest Tests Solar-powered Water Purification System - Using only solar power, a new water-purifying system by EnergyQuest, that is both easy to store and portable, will undergo testing by the Texas Water Resources Institute of Texas A & M. (Renewable Energy Access; Jan. 4, 2006)
  

• Delft water-purification method promises radical improvement - Delft University of Technology research has developed a compact and environmentally-friendly purification method, in which aerobic bacteria form granules that sink quickly. (EurekAlert; June 25, 2006)
  

• Wastewater treatment plants based on a full biological process - Onsite wastewater treatment process involves proprietary air-positive biologic reduction. (Export.gov.il) (See: [1])
