Removal of microorganisms from water due to passage through soil is of great importance in drinking water production. In the present study, results of laboratory experiments for the study of this issue are presented.

In this paper a model is presented which interprets virus removal as a function of collision efficiencies αβ and αλ, inactivation rate coefficient μl and rate parameter γ. Initial high removal is determined by ab, which decreases exponentially at a rate g ...
