• sieving action
• inertial impingement
One measure of the sieving effect is the largest pore; due to inertial impingement and diffusion, even particles that are considerably smaller than the mean pore size are retained. Thus, grades of filtration up to five times finer than the pore width can be achieved in liquid filtration, and even up to ten times finer in gas filtration.
The recognized physiological safety permits the use of filter elements made of PE-porös also in the food and drinking water industry.
Thanks to the superb chemical stability PE-porös is well suited for the cleaning of chemicals and solvents as wells for the recovery of valuable substances, like catalysts.
