Pool Filtration

This is the most common and user-friendly filtration. Because of its ease of use, Infinite Pools deploys this type of filtration in over 90% of projects. With this type of filtration, water passes through a cartridge made of pleated fabric or paper. The cartridge captures impurities and debris as small as 10 to 20 microns. Cartridge filters are easy to maintain and clean, as they can be hosed off or soaked in a cleaning solution. An example of a cartridge filtration system is a pool filter with replaceable cartridges.

DE filtration uses a fine powder made from fossilized microscopic plants called diatoms. The DE powder is spread on a filter grid or drum, and water is passed through it. The DE particles act as tiny sieves, trapping particles as small as 2 to 5 microns. DE filters provide the highest level of filtration but require periodic backwashing and recharging with fresh DE powder. An example of a DE filtration system is a DE filter tank with grids or a DE filter drum.

This type of filtration is not commonly used in today’s residential pools. There are only certain applications where this approach is beneficial, therefore it rarely presents as the optimal approach for projects Infinite Pools engages. It involves passing water through a bed of sand to remove impurities and debris. The sand acts as a physical barrier, trapping particles as small as 20 to 40 microns. An example of a sand filtration system is a sand filter tank.
