Aren't there better uses for the treated water than this? Can't you use it instead of desalinating salt water? Or just run this treated water through the same R

Aren't there better uses for the treated water than this? Can't you use it instead of desalinating salt water? Or just run this treated water through the same RO and you won't produce any brine and the result will be just as pure.
- rdtsc 1y agoYeah I think that's the difficulty here, the technology needs just the right kind of placement and the right surrounding setup. There is a desalinization plant nearby, they feed the water into the city, the city uses the water, the sewage comes to the water treatment plant, they clean it up to environmental release standards and instead of dumping it back into a river or the ocean, they use it together with stronger brine from the desalinization plant to produce some electrical power. From what I understand most municipalities do not directly feed sewage treated water right back to the consumer, normally they dump it into a lake or river first. A lot of that may just be an informal "yuk" factor not necessarily not having the technology. It's cool but everything sort of has to be aligned for it to work well.
- doikor 1y agoUsually you loop the treated waste water through nature for dilution (and more filtering if you use ground water) in case there is some problem with the treatment process. Also it is kinda hard to sell to people the concept of “you are drinking literal shit/piss” even though if you stop and think about it all lake/river/reservoir water is full of fish, bird, etc shit.
