Improved Design of Wound Filters for Enhanced Water Filtration Performance

Abstract

Wound filters are incapable of removing sub-micron particles, discharge particles under influence of rising pressure drop besides having lower particle retention efficiency compared to membranes. Producing wound candles with distinct density zones could offer a possible solution to the aforementioned drawbacks. In the present work wound density graded cartridges have been produced by changing winding pattern. Experimental results show improvement in their water filtration performance. The wound filters usually serve as pre-filter and if their performance is better then service life of the final filter will also be more.
