What does D.E. stand for in filtration systems?

D.E. stands for Diatomaceous Earth in filtration systems, which is a crucial component used for filtering water in pools and other applications. Diatomaceous Earth is a naturally occurring, soft sedimentary rock that is easily crumbled into a fine white to off-white powder. The powder is made from the fossilized remains of tiny, aquatic organisms called diatoms.

In the context of pool filtration, D.E. filters work by utilizing this fine powder, which has very small particle sizes that allow them to trap even microscopic debris and contaminants in the water. This results in highly efficient filtration, providing clearer and cleaner water for pool users. D.E. filters are considered one of the most efficient types of pool filters because they can remove particles as small as 3 to 5 microns, far smaller than what sand or cartridge filters can capture.

Understanding that D.E. refers to Diatomaceous Earth is essential for pool operators, as it emphasizes the importance of selecting the proper filtration medium to maintain water clarity and hygiene.
