There may be some filling water which leaked to the backside of the discharge pigs inside every test part discharge process of which has
been completed. It is important to have these water amounts collected especially in calyx areas discharged outside within the system before
the actual drying process starts. Generally it is done via disposing a Bi-Di pig and sponge pigs at different intensities from the backside.
The number and type of sponge pigs will be evaluated considering the physical condition of the pigs coming up from the receiving headpiece.
