@Fukuokian
That is basically what i am going to do.
Look at my profile picture, that was one of my pet sturgeons.
She was around 1 meter 80, any bigger they dont tolerate handling anymore, my biggest one was 2 meter 80(transmontanus and Acipenser huso)
i always had koi, sturgeons and aquaria.
My pond was at its deepest point over 2 meter in depth.... crystal clear water and all the values well within their limits and the fish where well fed almost even thick/overweight, with only water adding due to vaporising.
Water is pretty simple, i needs rest to let the dirt sink.
it needs 3 stages of bacteria to clean the water and rest to let junk sink.
oxygen to feed the bacteria's and keep the water health.
It needs to be conditioning from its source. if taking ground water in my case, in need to "de iron' it.
This can be done in several methods.
I prefer to add extra oxygen and let it flock, skim and stir for egg white.
for all water at a "gravity fed filter" before coming drinking water you need to add extra filters from 80 micron up to 5 micron.
So incorporate mechanical filtering.(bacterial filtering can do the job way better!!!) in both cases skip nah/lay(natronloog in dutch))
Toilet 800-1000 micron filter, if having clear water from pond skip this.
Washing machine 500 to 800 micron filter...if having clear water from pond, skip this.
Transcalent at 3 feet/1 meter in depth, reed newspaper at the bottom!
But de iron it and make sure the waters kh gh are low! so let it rest and give it oxygen and time, and rest again.
A double "vortex" filter will be your best friend.
Ffor shower no iron and max 300 micron, low kh and gh
Drinking without uvc, uvd or uvb under 22 micron if you are sure about good bacterias..
if not sure and no use of the uv 5 micron max, 3 micron will even filter out a virus.
Drinking water between 5 and 80 micron without propper filtration need minimum uvc and uvd.
Is it not that i did not mention coal filtered water.... thrust nature and her do the work....
Making drinking water is not so difficult if you have the propper knowledge.
I dont care what your source is, you can ask me anything about this subject but know the values you want and know the values you get.
Then we can talk about filtration and condition...there is so much
Water is much simpler than li ion chemistry...in my opinion that is, and my "basic" water knowledge....is pretty extensive, i think.
I can ramble over water conditioning/quality for hours......just ask on the forum, and i will find you and if not give me a pm/headsup!
For my "project rain water":
The water i indent to collect is going to be used for toilet, filtered to max 1000 micron.
But the water will go down 3 meters first and go up 2 meter 80 to fill the storage for the toilet.
For leafs and such filtration.
When that one is full (1500 to 2000 liters) we are at 3 meters again and that extra water will flow thru some water generators to a sinking pond/pound.
this whole system will be incorporated in the roof of solar panels.
This will be a another story
After the water gen(150w? an hour 24/7 3 months long?!?!)
the water from the sinking pond/pound will go to a four-chamber filter, so i skip a fortex filter.
From here it will become drinking water, also another story.
I hope this info will help you a bit and others.
