Swimming Pool Inlets & Filters
Whether your pool is inside or outside, it is of major importance to maintain the water quality for many reasons. Debris can start to collect in the pool’s water, which obviously needs to be cleared regularly to maintain water quality and hygiene. Dust, leaves and other particles are often blown into outdoor pools, but all sorts of dirt and debris can also gather in indoor pools. There are three main types of pool filters available, and you’ll need to select the one that best suits your needs:
– Diatomaceous Earth Filter
Diatomaceous Earth filters (DE Filters) are the most effective filters for most pools. If you want the water in your pool to be crystal clear than this filter is the right choice for you. We are usually unable to see particles, which are smaller than 40 microns. DE filters are able to keep the pool free of particles as small as 3 to 5 microns. These filters are made up of grids, which are coated with Diatomaceous Earth. Mined earth is used in the form of solid covering. This coat of diatomaceous earth acts as a sieve and helps in removing the debris. DE filters are able to filter the smallest grain of filth and hence can be considered most effective tool for keeping your pool clean. These filters are the most expensive to maintain, but also the most effective at cleaning.
– Sand filter
Sand filters use a similar sieve system, but obviously filter through sand to clean dirt from the water. Water passes through the sand, which then retains the dirt while letting clean water out into the pool. The process is similar to coffee filtration. When the flow of water starts to slow, it’s an indication that you need to clean the filter. The process is very simple. You let the water in through an outlet and remove it through the inlet. Instead of back into the pool, you let the water into the sewer. Through this process, you push all the dirt from the sand out into the drainage pipe to the sewer. The process is called “back-washing” the filter. If you still don’t get clean water in the pool, then you’ll need to change the sand in the filter. This may happen as rarely as once every 20 years, but can be closer to five years with major usage.
– Cartridge Pool Filter
If you don’t want to spend lots of time on maintaining the filter, the pool cartridge filter is just right for you. The cartridge is enveloped in a cylinder. All the dirt and dust will be collected by the cartridge. Cleaning of the cartridge is very easy; you simply remove it and gently clean it with water. Check the cartridge every time you clean, as regular wear and tear may create a need to replace it.
