Urgent Evoke

A crash course in changing the world.

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.

The 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.

Great selection of ideas and projects, like the Memcor project but would like to see a completely chemical free approach.

Well worth a +1 for KS

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
