Clean Water - Something to Think About

[suneel112]

As far as water pollution goes, there are two types. Chemical and Biological. The first one is harder to solve, since it requires removing the chemical form the water. In addition, current processes are very expensive. Innovation will be required to make it more cost and energy effective. [Maybe using a biochip with enzymes attached to silicon layers to remove chemicals from the water and deposit them on silicon chips, which can then be disposed of or cleaned as needed.]
Biological pollution is much easier to remove. Every two years or so, I go to India to visit my relatives. I do not have to drink the same "dirty" water that they do, however, because there is a product in India called "AquaGuard". It consists of a basic filter to remove large particles and then passes the water through UV radiation. It cleans water only requiring electric power.
The main problem with that is that several countries with water problems also face electricity problems (Including India). In fact, Bombay is the only city in India that has stable electrical power (from the Indian Government's Nuclear Power / Research Reactors). All other cities face power outages. One way to clean up the water in India could just be to provide a stable power source, which could be provided by building a Nuclear-Power based infrastructure.
In a continent such as Africa, though, this would be a much harder problem (where there is virtually no infrastructure to build). In addition, many parts of Africa are very dry, and the moist parts have standing water and waterborne diseases. A power solution could be solar or wind power (not to be mean, but I laugh at the 'Sterling Engine'. As if you are going to keep something ice cold in the continent with the most area in the tropics in the world.). Could it be that the "dirty" water in Africa gives Africans important immunity to pernicious water and insect-borne diseases? Hopefully not, then the problem can be "easily" solved. [this will still take billions of dollars and a vast aquifier / electric system].
Another word about immunity, when I come back from India, I usually get sick for a few days because I switched from hyper-irradiated "overkilled" water to "Indiana Water", world famous for its high ferric and sulfuric content. In addition, a little bit of chlorine cannot even do half as much as irradiating it with high-energy photons.

This is just my 2 cents worth.
