Water Purification Technology Equals Contamination Elimination

Sometimes we take the most important things in life for granted, like a clean glass of water. But such a seemingly simple luxury takes a long time to get right. Water purification technology actually dates back to 2000 B.C, and it’s still a work in progress. But perhaps one of the oldest industrialized purifying methods is distillation.

It started out with a pretty basic routine. During the first stage of this process, water is brought to the boil. The resulting vapor rises through a copper coil where it cools and returns to liquid form and is collected in a container. The purification takes place because the contaminants are too heavy to rise with the vapor and stay behind in the original liquid.

Experts eventually realized that methods of water purification such as distillation had several drawbacks. The process was not a complete purification – some contaminants still ended being transferred in the steam. Another disadvantage was the high cost of this filtering procedure. Over time, distillation requires large amounts of energy and water for the process to work effectively.

The larger part of the problem though, was getting rid of all the unwanted substances. Water contains a variety of impurities that are split up into several groups. Most of these offenders are called particulates. Some devices filter the particulates via coarse sand filters that have appropriate sized pore filters.

These filters usually have a pore size of 1 micron or greater. A human hair is about is about 100 microns in diameter, some of the smallest particles visible to the naked eye are about 30 microns in diameter. So you can see how challenging it is to filter out these particles.

To eliminate these tiny particles, a treatment called micro filtration is used. In some cases it is also referred to as sub-micron filtration. A micro filtration system has parts with pore sizes ranging from just under 1 micron to about 0.05 micron.

There are several design options out there to filter water. A good counter top or under-the-sink filtration system can help. The most common water purification technology systems used in the U.S. are carbon block and granular carbon filters.

Granular carbon filters and carbon block systems remove certain chemicals that are dissolved in the water and then trap them. Nevertheless, other chemicals, like sodium or nitrate, are not affected by the carbon and do not get removed.

Still, activated carbon is recognized by the EPA as an effective form of filtering out substances from water such as VOCs (volatile organic chemicals) and THMs (trihalomethanes).

If you learn how filtration systems work, you can make better choices for having safe water in your home. Some methods of water purification rely on multi-media block filters. They contain the benefits of activated carbon with several added advantages. A blended media is packed together in a solid to form a type of porous structure. This helps to filter out sediment and other harmful substances.

In the vast sea of filtration methods, choose a good home system that utilizes Active Carbon and block filters. It’s not hard to wrap your head around the basics of water filtration. With some simple research and checking the track record of the company you would like to purchase a system from, you can obtain a useful and reliable home system.
