The micro sieves were in good working condition.
Flocculation :
Outdated, too many improvements made on a
outdated design.
Only 2500 m3/h else the thickness of the flock
blanket will change
RSF:
No possibilities to enlarge the RSF inside the
existing building.
It is an upgraded installation (in the past
controlled by hand)
The pipe infrastructure is complex, and hard to
reach/repair.
