All filtration have the same purpose no matter where these filters are located. However, many filtration systems are found in water systems. This is to strain the water so that the water remains but the impurities are filtered out. The water should be as pure as possible. Particles can land in the water system because water is extracted from ponds, lakes and underground.
When water is taken from these places, animals live and breed in these waters, so the water needs to be cleaned. Also, water filtration systems can be installed in the homes. Some of them can be screwed right onto the faucet. Others can be placed inside the water system. Rust can also gather in the pipes so water filtration systems may also be needed in the homes.
Water filtration systems are commonly found in many different places where water is dispensed. When water is cleaned or purified, it must have the germs and particles taken out of them. If a person drinks water from a lake or pond where the water has not passed through a filtration process, the person could get sick because they ingested particles that damage their system.
Some people purchase another water filter system in order to better purify their water. Sometimes, water filter systems remove lead. Since water passes through pipes, they can pick up and carry particles that have rubbed off of the pipes. This could be a variety of metals including lead or copper. The main purpose of a filtration is the filter out the suspended particles.
