Description

Verfahren zur Verbesserung von Filterleistungen Bei Filtrationsvorgängen tritt häufig eine Filmbildung zwischen den abzuscheidenden Schwebeteilchen unter sich bzw. zwischen ihnen und den Filtermedien ein, welche zu einer raschen Erschöpfung der Filter führt. Es hat sich gezeigt, daß diese Filmbildung ihre Ursache in einer gegenseitigen Beeinflussung der an den Schwebeteilchen bzw. an den Filtermedien vorhandenen dia- und paramagnetischen Felder hat.Process for improving filter performance During filtration processes often a film formation occurs between the suspended particles to be separated or between them and the filter media, which leads to rapid exhaustion the filter leads. It has been shown that this film formation is caused by a mutual influence of the suspended particles or the filter media has existing dia- and paramagnetic fields.

Gegenstand der vorliegenden Erfindung ist es, die Filmbildung durch Irritierung der dia- bzw. paramagnetischen Felder zu verhindern. Man erreicht dies und dies ist die wesentliche Neuheit der vorliegenden Erfindung, indem man die zur Filtration bestimmten Suspensionen dem Wirkungsbereich von Magnetfeldern aussetzt. Als solche können beispielsweise elektrisch erregte Wechselfelder oder intermittierende gleichgerichtete Felder verwendet werden. The subject of the present invention is the film formation by To prevent irritation of the dia- or paramagnetic fields. One achieves this and this is the essential novelty of the present invention by considering the Filtration exposes certain suspensions to the range of action of magnetic fields. As such, for example, alternating fields that are electrically excited or intermittent rectified fields are used.
