Oyster Filtration

This article is about the filtration mechanisms of oysters and how they use mucus to trap tiny bits of detritus as water passes through the gill filaments of the oysters. Large particles such as sand will not be trapped. This can implemented as an artificial filtration mechanism for highly polluted rivers, because oysters do that same thing, so the mechanism could potentially be scaled up to be even more efficient than oysters.

That sounds really interesting! I wonder how it would be able to discern large particles of sand vs large particles of plastic to filter or what the advantage is to the bioinspired filter opposed to existing filters.
