What is a pool filter system? Understanding the basics of pool filtration

Eager to ensure your pool is filtered to perfection?

Regardless of whether you’re searching for a swimming pool filtration system that can handle the high-traffic requirements of a commercial swimming facility or a system that’s better-suited to small, residential pools, rest assured that our team can help.

The experienced engineers at Chemsol have designed, installed, and maintained a wide range of swimming pool filtration systems across the UK.

For a clear overview of what a pool filter system is, how it works, and why it’s essential for pool maintenance from the team of experts at Chemsol, simply carry on reading.

Why is filtration important for your pool?

Swimming pool water filtration is essential for both safety and enjoyment purposes. Not only does effective pool water filtration support high sanitation which helps to prevent the transmission of infectious waterborne viruses, but it also ensures an improved user experience.

A crystal-clear pool composed of water that is such high-quality that you could drink it, plays a vital role in encouraging the use of commercial and residential pools alike.

Key components of a pool filter system

On top of the essential swimming pool filters and material, a complete pool filter system must include many different key components, such as:

Pool main drain and skimmers

The main drain (at the bottom of the pool) and skimmers (the openings that are built into the sides of the pool walls) are designed to pull in dirty pool water, alongside any other debris including leaves, skin, and hair.

Pumps

For the main drain and skimmers to do their job, the pool filter pump is crucial. This key component creates suction and circulation, ensuring continuous flow of water through the filter. As a result, water stagnation and the accumulation of dirt is prevented.

Pool filters

Naturally, the heart of all swimming pool filters is the filter itself. As the water enters the filter, debris is filtered out using a porous material (typically, sand, diatomaceous earth, or cloth) and the water is clarified.

Heaters

In many cases, the clean and sanitised pool water will then be fed through a heater to warm it up, ensuring the pleasant temperature of the pool is properly maintained.

Plumbing and valves

Throughout the pool filter system plumbing, there’s also a variety of valves that prevent filtered water from travelling in the wrong direction, while also keeping dirt and debris from re-entering the pool.

These valves can be used to control the water flow, adjust the water pressure, and prevent water from entering areas of the system that are being repaired or maintained.

How to choose the right pool filtration system

When it comes to choosing the right filtration system for your pool, there’s a range of factors to consider. From price to the quality of filtration, it’s important to understand the unique pros and cons of each swimming pool filtration system to help you make a more informed decision.

For example, the filtering capability of your pool filter will vary depending on the type of filtering mechanism you use. By way of illustrating, sand pool filtration can filter out dirt and debris between 20-40 microns.

Cartridge pool filtration, on the other hand can filter out impurities between 10-15 microns, while diatomaceous earth (DE) can remove dirt and debris as small as 3-5 microns. As a result, DE may seem like the best option.

However, although DE provides the purest filtering results, it’s also a more expensive and higher maintenance option than other filtering materials.

Your budget, frequency of pool usage, and filtration quality will therefore all play a role in determining the best pool filtration system for your home or commercial premises.
