Abstract

Verfahren zur Vorhinderung yon Verockerungserscheinungen an Steigleitungen, Filterbrunnen, Brunnenelementen und anderen wssserfuhrcnden Objekten. Teil3: Einsatzmoglichkeiten und Ergebnisse an PraxisanlagenSummary: After the description of the present state of knowledge and the theoretics1 fundaments as well a8 the results of laboratory and field experiments given in preceding communications, this part presents the results from the application in a rising pipe of a well in an open-cast lignite mine. There is represented the technical design of the electrochemical polarization syatem, inclusive of the power supply, for anodic polarization. At current densities of the order of pA/cmzthe pipe does not Hhow m y noticeable ferric incrustation after five months, whereas previously after half that period the pipe was helf-clogged.
