7 Log Virus Removal in a Simple Functionalized Sand Filter.

Viral contamination of drinking water due to fecal contamination is difficult to detect and treat effectively, leading to frequent outbreaks worldwide. The purpose of this paper is to report on the molecular mechanism for unprecedented high virus removal from a practical sand filter. Sand filters functionalized using a water extract of (MO) seeds, functionalized sand (f-sand) filters, achieved a ∼7 log virus removal.
