What's in rodi waste water?

What's inside the rodi waste water. I know chlorine is removed from the carbon. I know mineral content is high but what else is in it? Is there nitrates or ammonia in the waste water?

High TDS water

If you were to test your tap water, I believe it's just higher values of the same stuff, minus whatever is completely removed by your carbon block.

Mostly dissolved salts of calcium, magnesium, sodium, carbonate, sulfate, phosphate, nitrate, and silicate. The RO/DI effluent has about 20-25% higher salt concentration than your inlet water.

What else makes it through the carbon? Is chlorine/chloramines the only thing that should be completely filtered?

For carbon that is not fully spent, usually chlorine and chloramines are removed. Other dissolved organics in the water will be filtered out along with some of the copper from piping.

So it does remove nitrates?

No, it's not particularly effective on dissolved inorganic salts.
