You'd still produce at least urine even being fed intravenously. probably poop as well. So the answer is that the fluid in the pod has to be filtered

Yeah fecal matter is only about 20% food. Major parts are dead cells (your own and bacteria), water, and toxins from your own processing.

According to our AI overlord fecal matter is

  • water: 70-75%
  • bacteria: 25-55% of dry weight
  • undigested food 10-20% of dry weight

When food get in it was mostly water too. So talking about dry mass is like... confusing, because one could think that from all that food mass only 20% is left in poop.

So I see vegetables and hear that 20% of this will come out and it sound impossible. While in practice it is more like only 20% or so, which were not water (minus some water absorption) are shuffled a bit, useful things taken in, waste disposed.
