would purify up to 150 million of the 250 million gallons per day

first uses microorganisms to remove ammonia and other nitrogen compounds from the water;

and only 1/10 as salty as sea water

= = =

So, now there is 100 million gallons per day, with 250 million gallons worth of poop in it.

Where are they putting this poop, who is cleaning the filters, etc.

And how about those poor little microorganism, now loaded with that nasty nitrogen?

And only 1/10 as salty as sea water, so we can dilute it down with good water, and you can get used to it. And just what ‘salt’ is in the water?

Same place they're putting it now. The effluent from a modern wastewater treatment plant is nearly drinkable, and generally cleaner than the body of water into which it is discharged.
