D.E. and Cartridge Filter Cleaning
DIATOMACEOUS EARTH (D.E) / CARTRIDGE FILTERS
Diatomaceous earth (D.E.) removes the smallest particle size of any pool and spa filtration device. Tiny fossilized skeletons of small sea plankton (diatoms) are used to trap undissolved material. D.E. filtration is said to be in the 2 to 6 micron range. The D.E. is held against a grid device or septum by the movement of water. The grid is covered with a cloth like material and the D.E. forms a "cake" or coating on the cloth. Water passes through the D.E. with the suspended material trapped in the channels of the skeletal material. / D.E. is considered to be a disposable filter media. When the pressure reaches 10psi (70 kPa or 1 bar) above the normal cycling starting pressure, the filter must be cleaned. In most cases it would need a backwash, but we manually clean our filters every 3 months / 4 times a year during the filter operation. We charge $78.00 for Cartridge and $99.00 for D.E. filters. 469-400-4404
