Neutalization of Acid Mine Pond

[GWJPE]

I know the pH of a mine pond (3.6) and I have a good estimate of the pond volume (168000 C.F.). Can someone help me determine the amount of Hydrated Lime Ca(OH)2 I need to to treat the water so that I can discharge it at a target pH of at least 6.0?

If it helps, the mine pond was created from strip mining coal that contained pyritic sulfur.

Thanks.

Nobody could do anything but guess (probably low) unless you do a titration of a few samples of the water.

Is this homework??

Mixing properly would also bean issue. A better approach would be to pass the effluent through a bed of crushed limestone (calcium carbonate) to neutralize the acid. The reaction is self-regulating.
