“mermaid's wine glass” algae — Algae The macroscopic genus of algae known as *Acetabularia* is commonly called “mermaid's wine glass” because of the distinctive umbrella-like shape of the tips of its stalks.

Diatomite, also known as diatomaceous earth, is highly effective for filtration due to its physical structure. It is a porous, friable sedimentary rock composed of the fossilized, siliceous shells—or frustules—of diatoms, which are microscopic, unicellular algae.12

When used as a filter medium, this powder is typically supported in a thin layer on a fabric or metal screen. Because the material is naturally porous and granular, it acts as an efficient physical filter, trapping suspended impurities and particles as liquid is pumped through the layer. Its ability to clarify liquids makes it a standard choice for processing various substances, including alcoholic and nonalcoholic beverages, as well as for specialized water treatment applications like public swimming pools and industrial systems.31
