Slow sand filters have been shown to remove pythiacious organisms from captured runoff water. In this study, Tobacco Mosaic Virus (TMV) was regularly added to irrigation runoff water. The virus passed through the sand filters for approximately 5 weeks, but gradually reduced to undetectable virus titer using ELISA during week 6 to 9. This is the first report that showed slow sand filters removed TMV from runoff water.

Slow Sand Filters: A Biological Treatment Method To Remove Plant Pathogens From Nursery Runoff
Oki, L.R., Nackley, L.L., Pitton, B. (University of California Davis)
Slow sand filters (SSF) can provide high quality water from untreated sources including irrigation runoff. A microorganism community develops on the sand and can breakdown a wide range of pollutants including plant pathogens. We studied the capacity of these filters to remove different kinds of plant pathogens from irrigation runoff. SSFs removed Phytophthora capsici after microbial establishment and after a simulated seven day pump failure in previously established SSFs. SSFs did not remove F. oxysporum after seven weeks. The SSFs were also able to remove tobacco mosaic virus from inoculated runoff water after 6 to 9 weeks of exposure.
