Cleaning by centrifugal force
With the centrifugal filter technology solid fines are removed from the process water with a centrifugal force which is up to 2012 times higher than the gravity of the earth. Oil and / or extremely fine solids < 1 µ can be removed by adding flocculents. The compound utilized for the finishing operation remains largely in the process water for re-use in the finishing process.
