How effectively we can seperate microplastics?
Yesterday I was playing around with some PTFE nanopowder and mixed it with achohol and applied it on my mountain bike chain.
I am wondering if I throw this powder in river, are water cleaning units able to remove nano particles from the water? Not that I am going to do this, just curious.
- mc32 7y agoI think that depends on size. Some systems remove the larger nano particles but are not yet capable of removing the smaller ones. Here are some numbers: https://pubs.rsc.org/en/content/articlehtml/2017/ra/c7ra05690g https://pubs.rsc.org/en/content/articlehtml/2017/ra/c7ra0569...
- xzvXSvz 7y agoIf your filter is fine enough, sure. But then you force higher energy costs to clean the water. "Not that I am going to do this," Sure, but eventually you'll wash your chain, and reapply the powder. So the particles end up in the river anyway. If you're interested, read up on how PTFE is produced. Specifically the case in WV and Ohio with DuPont's precursor PTFE plant.
- gingabriska 7y agoUnfortunately you are right. But what can be done? There are dry PTFE lubricants available in market and they work so well compared to traditional Grease in dusty environment that I don't see people giving up these.
