subsurface. In this study the inactivation of viruses in the presence of quartz sand was examined. The bacteriophages
MS2 and X174 were used as model viruses. Experiments were performed at 4 ◦C and 20 ◦C,
under constant controlled conditions, to investigate the effect of virus type, temperature, sand size, and
initial virus concentration on virus inactivation. The experimental virus inactivation data were satisfactorily
represented by a pseudo-first order expression with time-dependent rate coefficients. Furthermore,
the results indicated that virus inactivation was substantially affected by the ambient temperature and
initial virus concentration. The inactivation rate of MS2 was shown to be greater than that of X174.
However, the greatest inactivation was observed for MS2 without the presence of sand, at 20 ◦C. Sand
surfaces offered protection against inactivation especially under static conditions. However, no obvious
relationship between sand particle size and virus inactivation could be established from the experimental
data. Moreover, the inactivation rates were shown to increase with decreasing virus concentrationhttp://creativecommons.org/licenses/by/4.0/Journal of Hazardous Materials233-234148– 157A74-JoHM-12.pdfChania [Greece]Library of TUC2015-09-23application/pdf1.4 MBfree
