filtrátu

Filtrát is a term originating from Latin, meaning "strained" or "filtered." In a general sense, it refers to a liquid that has passed through a filter. This process separates solid particles from a liquid or gas, leaving behind the purified substance. The specific nature of the filtrate depends entirely on what was being filtered and the type of filter used.

In chemistry and biology, filtrát commonly refers to the liquid remaining after a filtration process, such as separating precipitates from a solution or isolating cells from a culture medium. For example, in a laboratory experiment to purify a compound, the liquid collected after filtering out impurities would be the filtrát. In brewing and winemaking, the clear liquid produced after filtering out yeast and other solids is also considered the filtrát.

The term can also appear in other contexts. For instance, in soil science, soil filtrát can refer to water that has percolated through the soil, carrying dissolved minerals and organic matter. In the context of wastewater treatment, the liquid that emerges from a filtration unit after the removal of suspended solids is the filtrát. The quality and composition of the filtrát are key indicators of the effectiveness of the filtration process.
