Abstract

In a system for filtering liquids with the help of a granular filtering substance deposited in the filter by means of the liquid to be filtered, the clarity of the filtrate, or the liquid to be filtered, is detected by a photo-electric device which controls the feed of filtering substance to the liquid.
