Investigations concerning the recycling of filter dust from electrostatic precipitators in the glass industry

Abstract

In the container glass industry the recycling of filter dust was applied from the beginning of the waste gas treatment - first mainly in flint glass furnaces. It is reported about the experiences concerning handling, dusting, and refining behaviour. Moreover, the results of a research programme, investigating the danger of enrichment with toxic components in the molten glass, in the filter dust and in the residual emission are presented. These experiences were altogether positive - so that until now the filter dust in the container glass industry and meanwhile also in the flat glass industry has been completely recycled.
