You can compare it to centrifuging blood samples in tubes to separate plasma from blood cells: by spinning the tubes, the heavier components (like red blood cells) are separated from the lighter ones (the clear plasma) by weight difference. Hydrocyclone technology is even more powerful and creates a strong vortex to separate the particles from the waste water, preventing it from coming into the water system or rivers.

It was already an existing technology used in various applications (pulp & paper, mining, air purification, petrochemical industry etc.), but they do not do it the way ECOFARIO does.
