In theory, there is going to be certain amount of force, which when applied will wash or nudge off the colonies of bacteria. So, you assume that the design has reduced the applied force and therefore retained the colony. hmmmm....... I really do not know if the claim or your assumptions have any basis. I think it sounds a little simplistic. Part of the assumption is that the force is constant for the life of the filter media. I cannot see how this could be true, given that over time, there would be a build up of bio-film and detritus. Any media, with build-up would start to produce its "own protected zones" as it accumulates bio-film/debris.

Perhaps someone with more technical understanding can enlighten me further, or at least find the holes in my logic.
