The biologically active, slow-flow sand filters of lake water treatment would remove nanoplastics from the raw water very efficiently. This was shown both in the laboratory and in larger, realistic tests and modelling.
This is good news for those who are deciding upon what kind of water treatment system to implement. This is dependent, of course, upon how badly the SHTF, resources available, and permanence of location.
