A device that promises when it comes to reducing water pollution have produced australian researchers. They are made of water filters made from a mixture of clay and organic materials like rice husk, leaf tea or coffee sediment. And as the water squeezes through the filter to stop pollution in it. Another product, that turns contaminated water into safe drinking water, a cheap filter that is distributed to victims of tsunami in South Asia. He uses the process of osmosis to waste water treatment. Having to remove harmful bacteria that filtered water is disinfected with chemicals. Bruce Bifoj working for an Australian company Memcor that invented the filter: "The process is based on micro fiber membranes, which are essentially drinking straws with a microporous wall structure. We miss the contaminated water - and it's water from local streams in Windsor - across the membrane in order to get pure filtered water that can be disinfected and chlorine.
company now builds large fully automated plants for water. The same company mass-produced versions of the portable water filter that treat polluted water. Ret Butler, who works for a company that owns the MEMC was invented in the small units. He says that these devices could save the lives of millions of people. "I think they will be of crucial importance, because we know that, after such natural disasters, diseases that occur are transmitted through water - such as ch***ra and typhoid. Therefore, portable water filters are important in the future."
Susan Murkot, a research engineer at the Massachusetts Institute of Technology in Boston, says that the use of water filter technologies can benefit millions of people in countries like India, China, Bangladess, Ghana, Mexico and Peru. "This kind of very simple technologies that use local materials, a cost and easy to use, consider sustainable technology appropriate for the most vulnerable population in need of safe water worldwide."
The state Michigan, the American, where the Midwest, the city of Grand Repids opened a factory that uses a new method for the disinfection of waste water and turning to drinking water. The system uses ultraviolet light instead of chemicals to the water cleared. Ultraviolet rays disinfected waste water to the point that bacteria and other harmful micro-organisms can not re-occur. The mayor of Grand Repids Hartvel George says the system is already helping to improve the quality of water supplies in the city. "The water that comes from the Grand River plant for waste water, when passing through the treatment of ultraviolet rays, but the cleaner river water itself."
Sky Veisman, a specialist in water
treatment in the U.S. Agency for International Development in Washington, says that the new water filters that can be used at home can remove harmful contaminants from water supplies. "The company Proctor and Gamble here in America distributes product called" Pure Product "that allows people to disinfected drinking water at home. Centers for Disease Control of the U.S. government has a program called "safe water system. All these technologies are very important, because no matter how pure drinking water comes from wells, people still need to have a lot of knowledge to re-contaminate the water before you use it in their home."
Supermodern plants like the one in Grand Repids are
often too expensive for developing countries. So many global companies are now spending their funds for research and development of cheaper water filtration systems that require less energy for their operations. These new technologies could have enormous benefits for an estimated one billion one hundred million people worldwide who live without safe drinking water.http://www.ekoforum.org/index/vest.asp?vID=163
