Dead-end Ultrafiltration Water Collection v1

Abstract

Dead end ultrafiltration is the most basic form of filtration. In this case a Rexeed #25S Filter is used with a peristaltic pump to pull volumes from 10L to 100 L through nanometer sized pores ( approximately 30 kDa). This size selection is perfect for capture of viruses, bacteria, protists and even larger particles and organisms. The large collection volumes made possible by this method have great value if there is a need to examine rare members of a community such as pathogens.
