Also if this is a concern, you might want to think about filtering equipment, but you want to filter before carbonation. I don't do this yet but am looking in to it. I have a canister system now (got it for free) but have not set it up yet, but think I might like to look in to a the plate systems.
I have found that just letting the keg sit for a week at 33 during the end of Carbonation, clears up the beer a lot, after the first pull.
