Answer:
The volume of feedstock needed to mantain an organic load rate of 2 kgVS/day is 0.055 m3/day of feedstock.
The HRT is 20.6 days.
Explanation:
First, we calculate how many kg is 1 m3 of feedstock. We know the density, so we can calculate the mass:
If the VS are 6% in weight,
The volume per day needed to feed 2 kg of VS/day is:
The HRT depends on the volume of the tank and the flow. Its equation is
