Essay on Technology and Development Article shared by: Essay on Technology and Development! Technology refers to the use of tools, machines, materials, techniques and sources of power to make work easier and more productive.
November 30,Purdue University Maji Safi founder John Maiyo, and company adviser John Howarter, pour water into a slow sand filter that the company is developing to provide clean and safe drinking water to schools and communities in developing countries.
The technology, which can be used in plastic pails or gallon drums, utilizes sand and water to better disinfect the contaminated water. At the bottom of the container is a porous plastic water collection plate, designed at Purdue. Purdue Research Foundation A Purdue-affiliated startup has developed a low-cost, low-maintenance slow sand water filter technology to better provide clean and safe drinking water to schools and communities in developing countries around the world.
Chad Jafvert, a professor of civil engineering and environmental and ecological engineering; and John Howarter, assistant professor of materials engineering and environmental and ecological engineering, are company advisers.
The company installs groundwater wells, and provides ceramic filters and slow sand filters, in western Kenya where safe water is not readily accessible. At the bottom of the container is a water collection plate, designed at Purdue. The sand provides a large surface area on which microbial growth occurs that metabolizes the dissolved and particulate organic material in the water.
The point-of-use slow sand filters are made from readily available five-gallon plastic pails or gallon drums. Instead we use a porous plastic plate enclosed within a mesh bag," Jafvert said.
There is only the sand to sieve and rinse, instead of sand and different gravel sizes. It provides easier maintenance and makes for easier filter transportation and final assembly.

Maiyo said that after 30 minutes of contact with the chlorine, the water is ready to drink. Each gallon drum filter can process liters of water each day. With five filters installed at one school, this meets the needs of over children and teachers at the school every day.
The idea is that the microorganisms do the work to remove organic materials from the water so the only energy demand is pouring water into the filter," he said. As a disinfectant, chlorine is very inexpensive in the countries where we have installed filters, so there is no huge investment required by the communities to use the technology.
The company is a member of the Purdue Startup Class of Purdue has 27 startups based on Purdue intellectual property that were launched in the fiscal year. Maji Safi plans to improve the filters based on feedback from the communities.
We've heard from multiple community leaders and the feedback is always 'how can we get more? We're open to partnering with a local manufacturer in Kenya or elsewhere who would be willing to do a trial run of parts manufacturing for 1, filters, which would be a huge step forward.2.
Finland: Finland is the country that tops almost every field such as the economy, health, politics and the technology. It is due to their aim to make the country first in the technological race by launching high technological barnweddingvt.com per capita income of Finland is much greater than many other European countries which clearly explains its massive advances made in technology over the years.
Developing countries such as India, China, Iraq, Syria, Lebanon, Jordan and some Africa's countries, have been affected by globalization, and whether negatively or positively, the economies of.
Today, countries are classified as developed and developing countries. The major categorization is based on economy and the application of science and technology. If carefully analysed, one gets to understand that countries which have a strong base in science and technology are the ones that developed faster.
lowed many in developing countries to learn about life and mores in other parts of the world, technology on labor market outcomes. And it is weakest, at least in the economic literature, on the impact of new trends on gender roles and norms, so that discussion is more tentative and speculative.
Globalization’s impact on gender equality. Technologies, capital, products and services are allowed to enter from developed countries to developing countries. It is the developing countries which needs to be adapted with the changing situations and to accept those new ideas for attaining higher level of socio-economic development.
Appropriate technology is most commonly discussed in its relationship to economic development and as an alternative to technology transfer of more capital-intensive technology from industrialized nations to developing countries.
