How Does The Filtration Of A Swimming Pool Work?       

Pools might differ in size, features and shape. But basically, they all function in a similar way. This means that almost all pool owners use a mix of filtration and chemical treatment to cleanse the water. Now, keeping that in mind, as a pool owner, you need to have basic knowledge of different swimming pool filteration systems. 

Water Circulation Pump

This is the first step towards cleaning the water. An electric-powered motor spins the impeller, which is present inside your pump. It pulls up the pool water through the suction side, and then pushes it through the pressure side. Next, the water gushes into the filter for another round of cleansing.

Knowing the Filters

The primary task of the filters is to free water from different types of debris and gets pumped into the filteration system. Depending on the type of filter you choose, it can pass through various media such as Diatomaceous Earth, sand, fabric and others. However, after passing the media, water flows back to its outlet pipe before returning to the pool. For maintenance, experts recommend backwashing the pool water at regular intervals.

Varieties of Pool Filters

You can choose from any of the following filters, depending on budget, time and need. The three types of filters are as follows:

  • Sand filter: Suggesting the name, it uses sand media to cleanse pool water. These are one of the most used friendly filters. It may filter 20 microns of debris. However, there are many new-age alternatives that can catch even smaller particles.
  • Cartridge filter: They make the water run through a polyester cloth or corrugated paper. You cannot backwash them. This means you have to clean them manually and replace them within proper intervals.
  • DE filters: This latest variety of swimming pool water filter systems cleanses water while it flows through a system of grids. These grids have coatings of fossilized powders. Such powders have their source in the diatom, or the remains of marine organisms. You can maintain them by backwashing once or twice a year. And though the most expensive of the kind, they are capable of catching debris as small as 3 microns.

Filtering time taken

Most experts opine that in public pools, water needs to pass through filters many times a day. They call it the “turnover rate.” However, privately owned or residential pools do not have any specific turnover time. But optimally, they need to pass through filters at least once every twenty-four hours.

Summing up

These apart, following preventive measures with a little bit of help from professional services, such as Atlantis Pool, can also be helpful. Regular professional maintenance can help save costs on running the filters. However, it is also important to understand the way your filter works. While cleansing your pool from debris and leaves ensure the life of the filters, it is also important to replace them whenever the needs arise.
