When we have completed the construction phase, we test everything and make sure all components and processes work perfectly. We also inoculate the bio filter so the plant can be used as soon as possible. During these procedures we draw in the staff who are going to operate the plant and instruct them in the optimal operation of the plant, both in practical and theoretical terms.
In other words, we give them a RAS course (a driving license). We then take them on a test drive and if they can drive the "car", and they like it, we give them the "keys", we commission the plant.
