Poliovirus Type I Removal by Montmorillonite Clay
The study arises from the problem of underground water contamination by viruses in percolating wastewater or eluted from landspread sludge. Since current water treatment facilities are unable to completely remove viruses from wastestreams, the task of virus removal by soils is required. At present the mechanism by which viruses are removed by soils is unknown. This study attempts to obtain a better understanding of virus transport through soil beds by looking at the adsorption isotherm of poliovirus to montmorillonite clay. Clay was chosen as the adsorbent because of its extremely large surface area and because the percent of clay in soil stands out as the most useful indicator of contaminant soil retention capability. The removal of poliovirus by montmorillonite clay was found to conform to a modified Freundlich isotherm. It was determined however that saturation of the clay particles was not reached so that a complete isotherm was not attained. Virus removal was found to depend on particle size and may be caused by association of the virions with aggregated clay particles.
