Sorption of viruses during flow through saturated sand columns

Article Abstract:

A study aimed at investigating the significant processes such as sorption and inactivation of viruses under saturated conditions is presented. The experiment utilized a column flow system to examine virus transport. Sand columns (9.2 cm in diameter and 10.5 or 20 cm in length) were applied with virus solution and subsequent tests for virus retention and inactivation were performed. The results of the experiment strongly suggest that using a well-controlled column flow system is more ideal in evaluating virus sorption than the batch equilibration method.

Estimation of nonaqueous phase liquid-water interfacial areas in porous media following mobilizatio by chemical flooding

Article Abstract:

Chemical flooding allows for the estimation of nonaqueous phase liquid (NAPL)-water interfacial areas in porous media following residual NAPL mobilization. An empirical model helped described the same relationship. Different salt concentrations enabled chemical flooding to occur at different total trapping numbers.
