What happens when it breaks down? Is it hard to get parts for?

What happens when it breaks down is some minor sulfate runoff occurs. Even if they didn’t clean the water, the environmental impact would be quite minimal. So this is like when you’re filling your boat with gas and the hose slips a bit – sure a bit of gasoline sheen occurs on the water’s surface, you feel bad for a about two seconds, and then you get over it because you realize mother nature is going to take care of it just fine.

Plant engineers will have considered this possibility. They will have built the treatment plant with one or more solutions to solve it. They may hold untreated water in a collection tank until repairs are made, design a modular system with several units including one or more spares that can be put on-line instantly, have repair parts available for immediate fixes, halt production until repairs are made. “What if?” is the primary question designers ask and they answer it before startup.

KH, conversely, what happens when you exhale? What happens when you pass gas? CO2 and Methane escape. Maybe we should regulate our bodies to prevent the escape of those horrible green house gases?
