Also known as a multi-layer filter, this is a closed vessel—made of metal or plastic—containing filter media through which the untreated water (raw water) that we wish to clarify is passed under pressure.

The appropriate filtration system is designed based on the intended use of the water, as well as the characteristics and quantity of the particles to be removed.

A multi-layer filter combines several types of filter media to remove suspended solids—such as sand, organic matter, heavy metals, and PFAS—as well as to address issues related to odor and taste.

The substances are retained not only on the surface but throughout the entire volume of the filtering medium, guiding the fluid through an intricate maze within the bottle. The water moves by taking twists and turns due to obstacles in the medium. Particles are removed from the water by a combination of simultaneous actions throughout the full depth of the bed – mechanical interception, inertial impaction, diffusion, gravitational settling, and surface adhesion mechanisms.

The method of removing contaminants imitates how nature works.
