Backpulsing

The use of microfiltration to eliminate colloidal suspended matter (pitch) from different streams in the pulp production process can lead to the increase of pulp quality as well as the reduction of some problems associated to the accumulation of such matter in the process. Previous studies [1] have

Direct visual observation (DVO) was used to view membrane surfaces at different times in crossflow microfiltration of yeast suspensions with rapid backpulsing at varied backpulsing duration and pressure. The DVO photos show that the membranes are more effectively cleaned by longer backpulse duration
