IA3M Project: SAND FILTERS

SAND FILTERS

According to the proposed subject, we are pretending to develop a prototype of one of these filters in a way that can be used in underdeveloped countries.
This filter will be built using low cost materials and high accessibility with the purpose that anyone on these countries can have one.

The purpose of this sand filters is to avoid the dissemination of illnesses by the pathogenic agents existent in water. The filter will be capable of remove the bacterial agents and solid particles in suspension. About heavy metals there is no way to remove these materials because the necessary instruments are very expensive and not very accessible.
We hope this filter will be capable of reduce the mortality rate associated to the dissemination of illness by bacterial agents. However, and because of pollution, there is no way to stop the spreading of these diseases because of the existence of heavy metals and other substances in water. Even with all this adverse conditions we hope we can make a good job in order to help poorest populations.

Today, we hear on television and read in newspapers and magazines, talking about the humanization and solidarity to countries in the 3 rd world. There is community aid from part of governments of industrialized countries. So these problems must not be only of governments but of all of us in general, the young people, because the future to all concerns and each of us must develop the potential that exists in each of the parts of the planet Earth. Then, we thought about applied innovations in 3 rd world’s countries because in these places, the resources are limited, and every day saw images of misery, degradation and even death. So I would like to, at least, think and try to bring into practice something that can help others, using a prototype that we intend to build.

This project, in addition to allowing me to develop capabilities, allows me to be more active in the world in which we live, taking position and helping the neediest villages. Since my area is science and technology, this project will enable me to develop skills and abilities in subjects such as physics and mathematics, as well as strengthen and encourage mutual and group work. I hope we can achieve all our projects now that would be more valuable to people in developing countries. Not that we think that we will change the world, but we can consider this as only an aid in relation to one of the many problems that these people face.

As one of my biggest factors of enthusiasm and concern (mainly at the level of new forms of energy production), soon I demonstrated interest in a topic related to renewable energies.
With the group made, in which all the elements had (and have) interest in a theme of renewable energies and innovations, it was necessary to "find" an issue / theme that would allow an objective work, since this Thematic can be quite broad. Thus, in accordance with the various discussions and presentations of ideas, it was devided the theme of our project: "Innovations Applied to the Third World."
The project covers various topics of my interest, and in my personal point of view, society in general. The "simple" idea of being able to help the most needy offers me a will and an enthusiasm to the development of the project. And since this project, in addition to the opportunity to work on issues that arouse interest me, allows me to acquire new scientific knowledge and culture (which would otherwise not be acquired) will bevery rewarding work with the group.
The development of a water filter, which can be produced at low cost, it offers a type of work that is not available in the area of science and technology. Having said this few words, I'll take this opportunity to express my optimism with the group.

I must confess that Project Area has always caused on me a lot of doubts, about the class model, the evaluation method and mostly about its importance to our life. My doubts didn’t go away but, until now, it has been a positive experience because it has helped me to be in touch with interesting knowledge and realities. So, it’s an open space where I can explore the world, explore myself and also improve some skills which will enrich me as an individual.
I still don’t know what degree I will take but working in this project has increased my interest on innovation, environment, technology, physics and developing countries, topics I would like to work since they are all related with each other, as we have seen.
So, I’m enthusiastic and optimist with this project and with the amazing innovations that keep being created every day, because I know that more and more people is worried about the underdevelopment countries issues, trying to find solutions, in a creative, environmental friendly and economic profitable or at least sustainable way (imperative factor).
