Flow Reversal and Pressure pulsation: Innovative technique to enhance flux in Nanofiltration
Abstract: Reduction in Permeate flux with the period of time is the major drawback for the Pressure-driven membrane processes. Concentration polarization and membrane fouling are the two major limitations for the Pressure-driven membrane filtration processes. They lead to the severe flux decline and that need to be controlled for the better process efficiency. The resistance determination provides basis for selection of membrane and appropriate pressure –driven separation process. This paper outlines …

Exploring Abrasive Flow Finishing of 3D Printed Mesoscale Passage
Abstract: 3-D printed parts and components have gained wide applicability which continues to increase day by day. However, due to the very nature of 3-D printing process, i.e. layer additions, outer surfaces are subject to poor finishing. Finishing 3-D printed parts is thus a necessity if they are to be used for prototyping or functional purpose. But, finishing remains a challenge, especially if the part contains passages that lie within and …
