How do I choose the right pool filtration equipment?

Understanding the types of filtration systems

Sand filters :

These filters use sand or glass as the filter medium to trap impurities in the water passing through. They are the most popular, and known for their efficiency and ease of maintenance. Sand generally needs replacing every five to seven years, glass on average every eight years.

Cartridge filters:

More effective than sand filters at capturing finer particles, cartridge filters use one or more filter cartridges that you simply rinse and replace on average every two years. These filters require very little water to wash.

Diatomaceous earth filters :

Diatomaceous earth filters offer the finest filtration, capable of filtering particles down to 5 microns. Although they are very effective, they require a little more maintenance and diatomaceous earth needs to be added regularly.

The size and flow rate of your pool

The choice of filter depends not only on the type of filter, but also on its flow rate. It should be proportional to the size of your pool. A filter with a flow rate that’s too small won’t be able to filter the entire volume of water in 4 to 6 hours, so the water quality won’t be optimal, while a filter with a flow rate that’s too high could lead to inefficiency and additional costs. The filter’s capacity is often measured by its flow rate, in m³/h. Make sure that the capacity of the filter corresponds to the volume of your pool and the capacity of the pump. The flow rate of the filter should always be greater than or equal to the maximum flow rate of the pump.

Energy considerations

Filtration systems can vary significantly in terms of energy consumption. Variable speed pumps are an excellent option for reducing energy consumption, as they can adjust their speed according to actual filtration requirements, reducing energy costs while maintaining optimum filtration quality. On the filter side, cartridge or diatomaceous earth filters use very little water for cleaning.

Easy maintenance

Choose a filtration system that suits your maintenance requirements. Sand filters require little attention, but periodic backwashing. Cartridge filters require more frequent cleaning, but are generally easy to handle. Diatomaceous earth filters offer the best filtration quality, but require very rigorous maintenance.

Durability and quality

Invest in a filtration system made from high-quality materials to ensure its longevity. Check user reviews and manufacturer warranties. A good filtration system can last for many years if it is properly maintained.

Our installation advice

Installing your filtration system is just as crucial as choosing the equipment itself. Correct installation not only ensures that the system works properly, but also that it lasts. Here are some essential points to consider when installing your pool filtration system:

• Strategic location

Accessibility: The filtration system should be installed in an area that is easily accessible for regular maintenance and repairs. This includes cleaning or replacing filters, adding filter media such as diatomaceous earth or making technical adjustments. Easy access allows you to carry out these tasks quickly and efficiently, reducing your pool’s downtime.

Proximity to the pool: The filtration system should be installed as close as possible to the pool. A long distance between the pool and the filter requires longer pipes, which can lead to a loss of head and a drop in pump performance. This means that the pump has to work harder to circulate the water through the filtration system, which increases energy consumption and reduces the efficiency of the system.

• Technical installation

Plumbing and pipework: Make sure the pipework is correctly sized and installed to avoid leaks and flow restrictions. Use pipes of the correct diameter to minimise head loss and maintain efficient water circulation. Avoid tight bends or complicated piping configurations that could impede water flow.

Stable support: The filter and pump should be mounted on a solid, stable base. This avoids excessive vibration that could damage the equipment over time. A concrete base is often recommended for most large filtration systems.

Protection from the elements : If possible, place the filtration system under a shelter or in a dedicated technical room. This will protect it from the elements and extend the life of the equipment. Make sure the space is well ventilated to avoid condensation and corrosion of components.

• Safety

Compliance with safety standards: strictly follow the safety guidelines specified by the manufacturer and the local standards in force. This includes the electrical aspects of the installation, such as ensuring that all wiring is carried out by a certified professional and that all connections are secure and protected.

Professional advice: For complex installations or if you are unsure of your ability to install the filtration system correctly yourself, we recommend that you call in a professional. An experienced installer can help you avoid common mistakes that could compromise the efficiency of your filtration system.

In conclusion

Choosing the right filtration equipment is essential to keeping your pool healthy and clear. By taking into account the type of filter, the size and flow rate required, energy considerations, ease of maintenance, durability and quality, as well as installation, you can ensure a pleasant swimming experience with low maintenance costs.
