How the BIOFILTER works: High performance triple filtration Technology
FILTRATION 1: Pre-filtration: Spunbond (made with thermally welded filaments, 100% polypropylene) mixed with Aqualen® fiber. Sediment filter which retains particles of iron, sand and neutralizes the development of germs, bacteria etc … and protects the activated carbon block
FILTRATION 2: The Carbon Fiber Block is composed of activated carbon from granulated coconut (Carbon Fiber Block) sintered and mixed with the Aqualen® fiber. The activated carbon is obtained after calcination of the coconut shells by injection of pressurized water vapor = physical phenomenon of the fixing of polluting molecules by the difference in polarity between the pollutant (+) and the activated carbon (-); activated carbon is regenerated by oxidation
FILTRATION 3: Aqualen® porous fiber (US patent 6514413 ; fiber with a diameter of 10 µm), mixed with activated carbon. This fiber resembles the roots of a tree which bind the granules of activated carbon into a dense structure. Its function is threefold, it:
allows to have a very large adsorption surface, i.e. 1,000 cm2 / g (33 times greater than that of conventional filters), that is to say a good distribution of water over the entire surface of the activated carbon (this avoids preferential water channels)
physically retains pollutants in its structure up to diameters of 5 µm (physical filtration of heavy metals, bacteria, arsenic and parasites)
incorporates in its structure ionized silver (negatively charged) which is bactericidal (neutralizes microorganisms, antibiotics, etc.), the silver is therefore not mixed with the activated carbon but retained in the microfiber
