Water Reuse And Resource Recovery: Trends And Opportunities

I'm not sure this is really sustainability, per se; but it is about water reuse. And even though the event was yesterday, the discussions were recorded and posted to the event site.

Learned about the lecture from https://spacecityweather.com/091417mostly-quiet-weekend-for-houston/.

First of all, I ask all Sustainability group members from this point on (November 2017) to be very cautious about adding new topical sections in our group ... each time a new section (or "entry" or "thread") is added, it's harder for everyone to see where "everything" is.

On the subject of drinking water in general, what I have seen so far in any publications in the last 30 years (printed in English) is 1) a lack of understanding of the full range of issues with drinking water, 2) a lack of understanding of the controversial and volatile directions that any conversation about drinking water can take, and 3) ignorance of the fundamental mathematical fact that any drinking water filtration method will never remove 100% of contaminants. (I have a master's degree in public health from UCLA, in California.)

Be deeply skeptical, therefore, of any "water reuse" concept, whether it comes from a sustainability group, permaculture, local government, or anyone else. Questions?

My question for you all, especially the library folk, is what name or term best fits a Sustainability group section on drinking water and related topics (such as those suggested by lesmel at the top of this thread)? Or something different?

Let’s hope this story progresses with good news.

‘Forever chemicals’ are eternal no more thanks to a pollution destroying device from Tacoma startup

https://www.geekwire.com/2023/this-startup-has-a-weapon-of-pfas-destruction-that...

For decades companies have added PFAS to firefighting foams, food packaging, carpets and fabrics, water-repellent clothing and non-stick pans. The long-lived chemicals are great at deflecting water, stains and grease — but they escape from products and now contaminate drinking water across the nation and are even detected in breast milk. PFAS are still in use, while researchers and regulators are increasingly concerned by their serious health impacts.

The startup’s weapon of PFAS destruction incorporates technology from the University of Washington and the Colorado School of Mines. It annihilates the pollutants in a device that can reach high pressure and temperature — hitting 570 degrees Fahrenheit. To that they add lye — an ingredient in soap — to create a caustic environment. The conditions dismantle the PFAS, breaking off the compound at its head, chopping up its spine of carbon molecules, and lopping off the fluoride molecules that run along the backbone.
The free fluoride then combines with calcium or sodium to make more benign compounds that are the same as those used for fluoridating water or as a toothpaste ingredient. Any carbon dioxide produced in the process is captured as a solid carbonate.

Testing shows that more than 99% of the PFAS are destroyed in treated water, Sharp said.
