2982: Water Filtration
Title text:
You'd think the most expensive part would be the quark-gluon plasma chamber, but it's actually usually the tube to the top of the atmosphere to carry the cosmic rays down.
The number one thing I love about Randall Munroe's particular brand of nerd humor is how genuine he is. His fascination with the natural laws of the universe is just that. It's not something he uses to hold himself over other people or to create in-groups and out-groups of people who know and people who don't. Even when his content is too complex for the average person it never has that subtextual "well you just wouldn't get it because you're not smart enough" vibe that so much other nerd humor has (looking at you big bang theory). He's genuinely inviting the reader to learn about whatever it is, whether they ultimately do or don't. He doesn't have that weird inferiority complex people get sometimes where people feel the need to defensively push others away from their interests to feel better about the fact that their interests happen to be niche in some way. He doesn't use it as a vehicle to fuel his ego. I've joked before that he's my "celebrity crush" but it's really just that he truly, genuinely wants to show you something he thinks is cool (and at least a little humorous) and as someone who's met a LOT of snobby nerds, I've always deeply respected that he isn't one. - sincerely, a professional vibe-checker (like, actually).
Big Bang Theory is less like nerd humor and more like autism blackface.
I never thought of it that way. Thank you for writing this out!
Well said. But.... I gotta ask....
sincerely, a professional vibe-checker (like, actually).
Yeah? Does that mean some degree of hiring manager?

thanks for the pasta
I've been waiting for algorithm-senpai to notice me...
The joke about adding well water back in again at the end is "correct". Reverse osmosis removes 100% of the solids from the water, but drinking water usually contains small quantities of solids - you can see a breakdown on the label of some bottled water. Completely pure water would leach all of the solids that have built up on the insides of water pipes over the decades, and leaches away the protective oxide layer from metal pipework, causing it to corrode surprisingly rapidly. It also tastes pretty shitty - kind of "dead". So a small amount of high-solids water is mixed back in after RO to bring the water back to normal levels.
All that other shit in the diagram? No. Purification and treatment takes place after the mixing step, it would be crazy not to.
It is a joke image.
But also yes. Pure water tastes awful. I'm one of those "super" tasters and I used to work for a water filtration company. Lemme say... what people think they want and what they actually want are often two different things.
Yeah, I'm with you there - worked for twenty years in water treatment myself. Water before it's been chlorinated / chloraminated for supply? Makes the best cups of tea and coffee ever - you need to boil it, of course. RO water? Vile.
This is why we have remineralization filters I love my highly insane filtered water. Goes through 10 stages before finally hitting reverse osmosis just to extend the reverse osmosis filter life. But it has a alkaline remineralization as the last step so it tastes amazing
Water taste is subjective. I absolutely hate the taste of high-mineral water and love pure water. RO or distilled water tastes absolutely amazing to me.
I assume you're some sort of serial killer. 😁
Least convoluted factorio seablock recipe
I'm going to refer to lakes as "cosmic ray sterilization basins" from now on.
Another article tag on explaixkcd that makes you go hmm 🤔😄
WATER. JUST PLAIN WATER. NOTHING DONE TO IT, JUST PLAIN WATER. POSSIBLY DRINKABLE. - Do NOT delete this tag too soon.
They always have fun with the "attribution" of that incomplete explanation tag for new comics 😄
Yeah I know, some are just better than others 😁
And none tickle me as much as the best {obvious thing} [Citation needed] ones 😄
lol all that just to add well water back in at the end
This is how I felt trying to build a water purification system in Oxygen Not Included
Is this to scale?
What would be required for my wife to drink tap water.
Here’s an idea. Once you’ve already split the water molecules with electrolysis, you should throw those streams into separate mass spectrometers, but without the detector obviously. The idea is, that with ions flying in a magnetic field, their mass would determine where they land. Anything that isn’t the right kind of isotope, let alone right kind of atom, would be separated into the waste stream.
