Clean water is essential to health and in many industrial applications. In this day and age, finding a clean water source is very difficult unless you live in a remote location free from human activities. Even then, there is the chance of naturally-occurring elements and compounds contaminating water sources. Private well water samples have revealed presence of contaminants that come from human activities. Clean water is not readily available. It has to be produced.
Clean water is produced with the use of water treatment systems. These treatment systems employ various chemical and physical processes to remove any contaminants in the water that makes it unfit for drinking, cooking and other applications. There are large-scale treatment systems that used for industrial and commercial applications. These systems are quite expensive and serve as a significant investment for businesses. There are home water purification system are more affordable for regular people. These treatment systems that employ similar technology to those used in industrial settings but on a limited scale.
Whereas industrial treatment systems usually employ as many treatments as possible, home water filters often only has the treatment technology required for a specific problem. That means that if the water problem involves too much iron, the treatment technology used is also only for removing iron. This is what makes home filter systems affordable. This is also the reason why testing of water sample is very important as it allows water treatment technicians to determine the right treatment technology needed for the home water filter.
