Abstract

A filter operating by surface action and having a shape generally tubular is fitted with a vibrator which has a frequency >50-60 periods a sec. The filter surface consists of longitudinal wires of triangular cross-section arranged side-by-side with their apices inward, in the form of a cylinder and the vibrator is placed inside and may be operated pneumatically or electrically. Means are provided to clean the surface periodically by vibration or by combined vibration and friction with granular matl. The vibrations of relatively high frequency have a bio-physical effect on micro-organisms such as algae, distributing the ambient medium, and causing them to break away from the surface. Lower frequencies, up to 50-60 periods of a sec. do not have this effect.
