Here’s the hard truth: no single system handles every complex stream. The real magic is hybridization. You mix and match. Start with AOPs to break tough bonds, then send it to biology, then polish with a membrane. It’s a treatment buffet.
You need to know your enemy. Is it high salt? High oil? Pharmaceutical leftovers? Test, test, test. Don’t guess. Guessing is how you end up with a repair bill the size of a sports car.
So, what’s the best system? The one you design for your specific, beautiful, terrible mess. Talk to an expert, run a pilot test, and build your beast. Complex water doesn’t stand a chance when you’re armed with ozone, bugs, and a little bit of anarchy.
Now go fix your water. I’ll be here with a refill, rooting for those tiny hydroxyl radicals. Cheers.
