Treated water should be less than 20ppm. But for drinking purpose it should be zero.

BOD of treated water should be nil, so as to make it free from organic matter.

It depends where the treated water is discharged to;

For discharge in Surface water its 20 ppm.
For discharge in Marine its 100 ppm.
For discharge in Land its 500 ppm.
Nil is for Drinking purposes.
