The swimming pool’s filtration system is like the heart of the pool. It keeps the circulation of, in this case, water, flowing so that your pool can run properly. In this article, we’ll go over the swimming pool filtration system and reasons why it’s important to maintain it. Filter maintenance keeps your pool water sparkling and clean, free of impurities and too many chemicals. It makes your water safe to swim in and that’s peace of mind for you. There are three types of filtration systems for swimming pools – Sand, Cartridge and Diatomaceous Earth (DE) filters. We will discuss how each one works. Sand Filters A sand filter’s tank is made of metal, concrete or fiberglass. It contains a thick bed of special-grade sand. When it is filtering, the dirty water from the pool comes in through the inlet pipe. This leads to the water distribution head inside the tank. Gravity pulls the water down to the sand where the sand particles catch dirt and debris. At the bottom of the tank, the filtered water then flows through the pick-up unit and out the outlet pipe. You can swap the sand out for a special type of glass which will not need to be changed as often. You should change the sand in your filter once every 3-5 years. Cartridge Filters Cartridge systems work by allowing water to go through a very fine filter surface. It captures any dirt, dust or impurities that attempt to pass through it. It holds them until you clean the cartridge filter or you replace it. Cartridge filters have more surface area than sand filters. They get fewer clogs and are much easier to maintain. Cartridge filtration systems operate at lower pressure than sand filters causing less back pressure on the pump so more water flows through the system. Cartridge filters are easy to maintain. It can be as easy as taking the cartridge out and washing it with a garden hose. You should replace your cartridges once every 3-5 years. Diatomaceous Earth Filters (DE) DE is the media inside the filter. That’s how it differs from the other two types of filters. DE is a fine powder produced by crushing fossilized exoskeletons of diatoms. Diatoms are ancient but similar to algae. They have porous bones which make them excellent filters for impurities, dust and dirt. The skeletons coat a fabric-covered filter grid which keeps them from going into the pool. You add new DE by putting it in the skimmer. The pump sucks the DE into place. Backwashing and addition of new DE is needed at least once a year for residential pools. Now that you know about the different types of filtration systems, we guess you can figure out why they’re important to maintain. Without them, your pool will get dirty and dingy. It won’t be swimmable and you’ll have issues keeping your pool healthy.
