How to Does a Filtration System Work?
A filtration system works by processing or filtering gas or liquid through a filter medium to remove solid particles. Learning how a filtration system works can help you to decide what type of filtration system is suited for your purpose.
The Science Behind Filtration
Filtration works by passing liquids or gasses including air, water or even oil, through a medium such as compact carbon or sand. Sand based filtration is actually the oldest form of filtration that filtered out particles through the repeated slow passing of liquids through the sand. Water filtration systems, such as carbon water purifiers, are good examples of how filtration works for home use. These types of filtration systems normally use a compact carbon based medium that filters particles from the water in your home removing impurities and making it safe for consumption. In this case, water is passed through a filter and cleaned through both a chemical and physical process that blocks unwanted materials and substances with molecular structures larger than water such as chlorine, waste products and even pesticides which can be harmful to your health.
Water Filtration Mediums
In addition to the basic carbon filter that is used to filter water, multimedia filters are another type of filtering system that combines carbon and other filtering mediums to increase productivity of the filter. The multimedia filters work by absorption and changes the atomic structure of the substance that is being filtered causing it to bond to the filter, thus improving the filtration process.
Water purifiers and reverse osmosis filtration systems may often be referred to as filtration, but many scientists find this to be debatable. Although reverse osmosis water filtration systems are popular, the processing is quite different and primarily designed for the desalination of seawater. Although it does filter salt from the water and changes the structure of the water via the process of osmosis, some experts do not feel it filters the water as efficiently as carbon water filtration systems. Such a system is significantly different from a carbon or multimedia water filtration system. Water purifiers, although used interchangeably with water filtration systems, are truly not equal, as a water filtration system is designed to remove unwanted chemicals and minerals, and it is not recommended for the removal of bacteria and viruses which is required to produce pure water. Chlorination is what removes bacteria and other parasites from our drinking water, and most municipal water systems implement this practice.
