What If You Flushed Toilets with Saltwater
Date: 2020-01-28 03:00:06
With fresh water being so hot an issue today, you would think people should save every drop of the precious liquid. But then you flush your toilet and realize you’ve just spent several gallons of clear water only to get rid of your waste. Why can’t we use saltwater instead, for example? How’s that saving the planet?
We have literal oceans of the stuff, and we can barely find any use for it. Well, there’s a huge trouble with salty water in the sewage system. You see, salt is hard. If you simply send tons of water from the oceans into the plumbing and sewers, several things will happen quite soon…

– The modern sewage system works with the help of water that carries waste to the disposal plants.
– Water is perfect for this kind of activity as it keeps the waste afloat and pushes it through the pipes.
– The sludge gets some special treatment to make it usable as a fertilizer.
– The water above the sludge, in its turn, becomes rather clear to the eye, but don’t let that fool you: it has billions of microscopic dirt particles in it that only wait to infect you if you have a drink.
– In any case, the water gets biologically purified and is almost ready to go back where it came from, meaning seas and oceans.
– The most popular method of finishing clean is treating the water with a disinfectant, such as chlorine.
– Another way to purify the water involves pushing it through a special treatment tank, or a humus tank, where even the tiniest particles and bacteria get stuck in the filtering matter, while the water freely runs onwards.
– If you’ve ever swum in the sea, you know that if you lick your skin, it’ll be salty to taste. And if you leave it to dry in the sun, you’ll also notice a thin smattering of white on your skin.
– The same applies to almost any surface saltwater might touch.
– The resulting wastewater will not be able to return to the oceans just like that, or be used for other purposes, for that matter.
– Bacteria spread in the water and munch on everything harmful they can find around. With saltwater, such a system won’t cut it.
– That doesn’t mean we can’t use sea water at all, though. We are, in fact, using it already, and have been for quite some time.
– here are several desalination plants sprinkled across the globe that work hard to convert sea water into fresh one.
– The existing desalination method is not perfect, of course, but it’s proven its efficiency. You can even drink the water after it has been devoid of salt!
– In rural areas and smaller towns where people live in their own homes, composting toilets are the best possible solution. They don’t need any water at all, collecting all you have to throw inside them with quiet dignity and then dumping it into the soil, making it richer.
