Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such

discoveries of new life‚ space exploration has led to much advancement‚ including ones that we use in our daily lives. An example would be those comfortable beds that are made of memory foam. Unlocking the mysteries of what’s beyond or planet is the solution to many problems we have here on earth. The possibility of finding new resources and life in space‚ overpopulation on planet earth and finding a new source of fuel are just a few of many reasons to encourage space exploration. Planet earth is slowly

What is water purification? Water purification generally means freeing water from any kind of impurity it contains‚ such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some

Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air to sustain

Introduction Water is necessary to life but it can be unhealthy too. In general‚ the water quality is poor in developing countries like Kenya. Water is a vector of diseases like yellow fever‚ diarrhea… Water purification is very important in these countries but people don’t have a lot of time to spare‚ they work or they are in the field and in general women must spend a significant amount of time walking to collect water. So we need to find a quick‚ easy‚ and economic solution that is as simple

Jonathan Chen Space Exploration There are many reasons on why space exploration has become a necessity for us‚ as the amount of money being invest on space exploration‚ has increased drastically. From 1950’s the amount of money spend was 89 million which was a large sum of money back then. While we move up in the years the amount of money on space exploration increases‚ for instance in the year 2010 it was the most amount of money spent on space exploration than any other year. A total of 18‚724
