Hello Timothy,
You can add a serarator but you will still have to empty it. (psst and not every 6 months!) maybe at the end of each day as a pack up routine.
I have a small DC with 90mm pipe, so I made my own from two buckets and a short piece of pipe

The dust as Kelly said vegies love it along with my friends Chooks.

If you use plastic buckets be sure to ground them to prevent static shock.

Regards Rob
