Abstract

A chemically active filtration membrane with incorporated lanthanum oxide nanoparticles enables the removal of bacteria and phosphate at the same time and thus provides a simple device for preparation of drinking water and subsequent safe storage without using any kind of disinfectants.

Keywords: biological stability; chemically active membrane; microbial growth; ultrafiltration; water quality.
