Re: Floss is boss but glass was a pain in the arms
Floss indeed is a very good medium for mechanical filtering. Except
that it clogs quickly, precisely because it is a good mechanical
filter, and becomes of little use for that purpose -- when clogged it
still blocks the passage of particles, but little water can flow
through to be filtered.
I shouldn't have said that floss could work as a biomedium, it has to
be replaced too often to develop a really good culture nitrating
Trivia for the day:
Modern polyester, whether bonded with phenolic resin and painted blue
or not, is the more healthy descendant of the early fiberglass floss --
the same material once sold as "angel hair" for you decorate your
Christmas Tree. Didn't look so good on the tree, looked worse in the
xrays of your lungs; and it left you kind of itchy as the glass
particles worked into your hands and forearms.
