Filtrationsbarriären

Filtrationsbarriären, sometimes translated as filtration barrier, refers to the natural or artificial structures that impede or prevent the movement of water and dissolved substances through a porous medium. In geological contexts, this can include layers of impermeable rock, clay deposits, or compacted soil that restrict groundwater flow. These barriers play a crucial role in hydrogeology, influencing the availability and movement of aquifers, and can be significant in controlling the spread of contaminants in the subsurface.

In a more technical sense, the term can also be applied to materials used in filtration processes. For example, in water treatment, a filtration barrier might be a layer of sand, gravel, or activated carbon designed to remove suspended particles, chemicals, or microorganisms. The effectiveness of such a barrier is determined by its pore size, uniformity, and the physical and chemical properties of the filtering material. Understanding the characteristics of a filtration barrier is essential for designing efficient water purification systems and for managing water resources effectively.
