Water refining, also known as water filtration, is the cleaning process applied to water to make it safe to drink. This could be a manual filtration, distillation or a chemical filtration or even reverse osmosis procedures. Today our water system is constantly being contaminated by storm runoff, waste from chemical companies, ground pollutants and households. Our water is not as clean as it once was, and water companies are fighting an ever tougher job in trying to treat our water to make it safe to drink.
Water companies do not always make huge profits, as water refining is an expensive procedure and in most Western countries water is relatively cheap when you have to pay for it. More and more private companies are now however entering the fray and are offering their own products and systems as an alternative to straight tap water, all claiming that their product is the ultimate and that they will purify your water and make it entirely safe to drink. Most of these systems would probably work in a small controlled environment, but when faced with hundreds of miles of piping to send their water through, many water companies actually produce clean water, but during the transport process might become contaminated due to corroded pipes, etc.
Apart from the demand of clean drinking water, many manufacturing plants require purified water for their products as well, and if there are any impurities present, this could place the production line at a risk of contamination and even shutdown should it be serious enough. So as you can see, water refining can play an extremely important part of our daily life, and so many people will just run their tap water, fill up a glass and drink from it without even thinking how the water came to the tap, if the water was safe to drink or not, and even how they could save some water and not let the tap run while not using the water.
Many countries in the world do not receive a reliable rainfall, and this results in some of the driest areas of the world, often desert regions, where water is more precious than gold.
So next time you throw contaminated articles down a drain, or leave a tap running, spare a thought for those who do not have running water, or have access to clean water and might have to walk many miles with containers to get clean water for their everyday use.
