Diatomaceous Earth Filters

Extremely fine filtration - Diatomaceous filters

Diatomaceous filters are considered to have the best performance with a filtration size of 5μm, and produce crystal-clear water. In order for them to operate correctly, regular cleaning is needed (every 3 to 5 weeks). However, they require backwashing every 2 months to eliminate built-up dirt. The diatomaceous earth released during backwashing must be collected to prevent it from entering the wasterwater system, and the level of diatomaceous earth in the pool must then be partially replenished.
