Sand filtration

Sand filtration is an effective method for purifying pool water without the use of chemicals. It needs to be combined with other disinfection methods to achieve ideal water properties.

Are you looking for an effective way to clean your pool water? Bet on sand filtration. It is one of the most commonly used methods for purifying pool water. This system uses a special filter filled with a layer of fine sand that traps impurities to ensure clean, clear water. Recently, we are more often replacing sand with filter glass or AFM activated filter material.

How sand filtration works

The principle of sand filtration is based on a physical process where water from the pool is fed into the filter and passed through a layer of sand. The sand effectively traps debris such as leaves, grass, pollen, dust and other micro-particles. These impurities remain in the sand while the clean water continues on into the pool.

The filter itself is usually housed in a special container that is connected to the pool system. The water is pumped by a pump into the filter and from there it is returned to the pool. The filter system is equipped with control valves that allow the water flow to be regulated and the cleaning cycle to be adjusted.

Maintenance of the sand filtration system

Regular maintenance of the sand filter is essential for its proper functioning. As the sand becomes clogged with dirt, it must be cleaned. Simply feed water into the filter in the opposite direction to the filtration, this will coagulate the sand, loosen the dirt and wash it down the drain.

At the same time, the sand in the pool filter needs to be changed every 3 to 5 years, because over time it becomes so dirty that it can no longer be washed and loses its effectiveness. With filter glass and AFMs, replacement is not needed as often as this results in more efficient flushing. Regular maintenance of the sand technology for swimming pools results in perfectly clean and healthy water.

Benefits of sand filtration

  • cleans naturally without chemicals
  • reduces the consumption of additional pool chemicals
  • maintains pH

Sand filtration is a proven and reliable method for effective pool water purification. Keep in mind, however, that a sand filter alone will not provide the desired water parameters. In order to keep the pool water 100% clean and healthy, sand filtration must be combined with another method of disinfecting the pool water. In our offer you will find a device for chlorine disinfection of pool water but also technology for chlorine-free water treatment, which is ideal for allergy sufferers and people with sensitive skin.
