Probably the best filtration process
Originally, diatoms are brown unicellular seaweeds. After they fossilize
only the siliceous frustule remains, giving a very porous light-weighted
white rock: the diatomite.
Adjuvants of filtration are made from this diatomite. By creating
a filtrating layer on a group of suspended distortable elements,
the diatomite stops impurities.
Diatomite filtration is a process that allows to obtain a fineness
of filtration of 1 to 5 microns, when limiting the speed
to 6,45 m3/h/m2 and filtrating continuously 24/7.
