Meaning
Filtration is an operation that separates a liquid from material retained as the liquid passes through a medium. Its importance lies in what is retained and why. The source can filter away extraneous dirt, clarify a liquid before crystallization, or distinguish soluble portions from an earthy remainder. These purposes are related but not identical.
Filtering also helps clarify a central distinction in the book's polemic. The denial of universally worthless dregs does not abolish every useful separation or require dirt from roofs to remain in collected water. An intrusion can be unsuitable to the intended inquiry, while a native residue can still possess power and a future use. Filtration supplies a practical case in which selection must be explained locally.
Use in the book
B1C10S003 begins the rainwater analysis by filtering away dirt associated with collection. The resulting water is described as clear, yet later it develops turbidity and a brown spongy earth. Within the author's demonstration, the prior clearing helps present the new earth as a product of inward alteration rather than merely visible dirt overlooked at the start. The cosmological identification of this earth as universal Gur remains his interpretation; the filtering does not independently establish that theory.
B1C10S009 filters the concentrated rainwater before the separation of the two crystalline forms identified as nitre and salt. B1C23S015 similarly joins leaching, filtering, and coagulating in the account of a vitriolic salt from Gur. These passages distinguish operations that must not be collapsed: water takes up material, filtration separates what does not pass with the clear liquid, and subsequent concentration reveals a bodily saline product. Filtering itself neither creates the salt nor completes all its further transformations.
B1C22S014 and B2C05S068 make the retained earth significant. Repeatedly altered salt can yield an earthy portion through dissolution and filtration, and the author connects that portion with the foundation of further fixation. B2C07S009 also includes filtering in a route aimed especially at purity. These uses coexist with the defence of residues because the decision to separate a portion is distinct from the judgment that it has no possible value. Filtration reveals a difference of behaviour; the next argument must determine what the difference means and what should happen to each portion.

Translation in this edition
Filtration, filtriren, and the imperative filtra are attested, as are several other inflected forms. In B1C10S003 the retaining medium is explicitly felt. The lexicon need not infer a uniform pore size, a modern filter material, or the complete removal of every dispersed component from that description.
“Clear” and “filtered” describe an appearance and an operation at a particular stage. They do not guarantee an eternally unchanged liquid or a chemically pure substance. The transformation of previously clear water is precisely what the author asks the reader to notice, so the wording should preserve that sequence rather than use clarity as a final definition of composition.
