Advanced filtration

DWTP

Advanced filtration is characterized by using membranes to separate the contaminants and impurities that the water contains. For this, the membranes have a specific pore size that allows them to remove all particles, molecules and microorganisms that are larger than the pore size.

Filtración avanzada (1)

The main classification of advanced filtration establishes four categories: Microfiltration, Ultrafiltration, Nanofiltration and Reverse Osmosis. The differences of each are the minimum pore sizes, being 100 nanometers (nm) for microfiltration, 10 nm for ultrafiltration, 1 nm for nanofiltration and smaller sizes for reverse osmosis. By having smaller and smaller pores, operating costs increase, as the prices for changing the membranes are higher and a greater pressure is required for the water to pass through the membrane.
