Why Treating Batches Of Water Is Necessary To Live?

According to many climatologists and political scientists the next world war may very well be caused by disputes, not over oil, but over a far more precious resource – water. Changing climate patterns and widespread pollution are placing resources of fresh and potable water under enormous strain and making it more necessary than ever before to conserve and treat to the water that we use.

John Adams from Neopuretech quoted, “The science of water treatment has therefore become more important than ever.”

It is not only drinking water that is of paramount importance, fresh or treated water is an essential component for industrial processes, medicine and agriculture. All of these are at the foundation of modern society.

Water treatment is a large scale industrial process that removes contaminating matter from the water so that it is suitable for the end user. For more information about purification of water, visitĀ

There are a number of processes that can be used in water treatment and these include both mechanical and chemical methods.

The first, mechanical processes can consist of allowing larger solids to settle at the bottom of large concrete lined ponds and then pumping the water to parts of a water treatment plant where further processing can take place. The second commonly used mechanical process is filtration. The most widely used filtration method in the treatment of water is sand filtration.

In sand filtration the waste water flows through a bed of extremely fine sand and in some instances larger pebbles which act to trap particles. At this stage of the water treatment process the majority of the remaining suspended particles are removed from the water.

There are many chemical processes involved in water treatment. However, the most common are the use of calcium hydroxide and chlorine.

Calcium hydroxide issued in the process of ‘flocculation’. Adding calcium hydroxide to the water causes very small particles to adhere to each other, making them much easier to filter out. Sodium silicate and ferric chloride may also be added to the water as these aid in the process of flocculation.

Without this process, many mechanical filters would be much less useful, says the author fromĀ

Chlorine is commonly used in almost every water treatment plant in the world.

Chlorine is carefully added in measured doses to the water to ensure that it reaches levels where it is safe to drink and be used in a variety of other industrial applications. The chlorine acts to kill quickly a wide variety of micro-organisms, bacteria and any viruses that might be present after mechanical filtration has taken place.

Chlorine doesn’t remain active for very long, around 8 hours is maximum, so it is used again at the pumping station as a weaker solution (along with small doses of ammonia) to ensure that the water remains safe to use right until it reaches the consumer or industrial user.

As potable water becomes more and more scarce new technologies for the treatment of sewage are becoming more common, include treatment with ultra-violet radiation and a variety of reverse osmosis treatments. As we move deeper into the 21st century, it is going to become more and more important that we continue to innovate as far as treatment is concerned, but that we also learn to husband our water resources more carefully.
