"The ESSE units were installed in 1999 for automatic raw sludge removal from the primary clarifier, since then they have been running at 8 cycles per day without any malfunctions. During this time, apart from a few defective initiators, no repairs or other work was necessary. We are therefore very satisfied with the units, which is why the lifting units are now being replaced by the successor models."
