Abstract:

A continuous filtration system for supplying an uninterrupted supply of filtrate from a solids-containing industrial process suitable for use by on-line automatic analyzers is provided. The continuous filtration system, which is particularly useful for filtering flue gas desulfurization process slurry to produce a solids-free filtrate for autoanalysis, includes a pair of filters connected in series which concurrently receive a tangential flow of slurry into the filter head that is discharged perpendicularly through a filtrate head. An automatic flushing system is provided to keep the filter membranes free of solid particles. An optional autoanalyzer for unfiltered slurry may also be included in the system.
