Hey everyone, I'm new to the forum and new to prepping as well and hoping to get some help with water filtration. I don't see much discussion on filtering pool water, so my apologies if I missed it somewhere and hopefully this isn't a stupid question. I have seen plenty of discussion on filtering and storing fresh water but I'm curious if there is a way to use the 22,000 gallons of saltwater in my pool? The salinity of my pool is 3600ppm, low compared to seawater but certainly not drinkable. In searching for solutions, I stumbled on something called the AEG Oasis which claims to be purpose built for this scenario but I'd prefer not to spend a grand on it. Looking more closely, it is just a simple RO filter that uses a DOW Filmtec filter with a 99% rejection rate. I called a couple of companies that sell RO filters and they didn't recommend filtering water above 2000ppm. However, I'm more interested in emergency situations than perfect taste. The Filmtec membrane has a 99% rejection, so in theory the water would end up at 36ppm. Let's say it doesn't work perfectly and gets 97% rejection, that's close to 100ppm which works out to around 100mg salt per liter. I imagine it would have a slight salt taste but would still be safe to drink? I'm curious what you all think and if any of you have a saltwater pool and have come up with solutions for turning it into drinking water when the SHTF? Thanks, Brian
this wont help today but a 3dp solar powered desalinator maybe in the works. How aerogel can make the ocean drinkable ,,, why do you have 22k gallons of salt water in your pool?
It's a saltwater pool that uses a chlorine generator to turn the salt into free chlorine. Instead of constantly buying chlorine for the pool, you just occasionally buy salt. It's a lot easier to maintain than a traditional pool, they've gotten very popular with pool owners. So, I figured if I have a 22,000 gal pool in my back yard, it would be nice to be able to use that water in an emergency if the municipal water is out of commission for an extended period of time.
To be honest, I never heard of someone having saltwater pool before, but it does make a lot of sense. I think you might have hit on a new topic. We certainly have discussed water filtration and etc. but never desalination of salt water to my knowledge. It is indeed an interesting topic... First question that pops up in my mind is if it can be done cost effectively. Now, the technology is out there because naval ships certainly have them and it has come a long way from the old days so...
My cement pond is a traditional chlorine pool, and all that I have to do is wait a day or two and the chlorine is gone. I would still need to filter/treat the water before drinking it, as it would quickly become a backyard pond, but it would be a large source of drinking water...while it lasts.
