ANALYTICAL ASSESSMENT OF GLASS FILTER ELEMENTS FROM A MUNICIPAL DUST COLLECTOR (AA3)

ISSUE

The incineration center of a Quebec municipality started up its dust collector unit with a new model of glass/PTFE filtering tubes.

TECHNOLOGICAL CHALLENGE

Having performed this test, the center's management wanted to know whether these new elements would be a good replacement for the usual simple glass type. For such, STS Canada was mandated to perform the relevant analyses to determine which type of filter elements were best suited for their operation.

RECOMMENDED SOLUTION

STS Canada performed the physical and mechanical analyses of the filter tubes. The results were interpreted to identify the most fitting type of filter element.

RESULTS

The analysis revealed that although both elements had a similar useful life, the glass/PTFE tubes presented better aeraulics properties than the actual glass elements. Moreover, the PTFE coating also offered better acid resistance.

With such close results, STS Canada recommended the glass/PTFE media be used only if their price was equal or lower. Finally, the analysis established that the useful life of the current glass tubes was 12 000 operating hours, which was shortly due. STS therefore recommended that the switch or replacement be done when that time was up.
