Maintenance work on agitators at MARIN (NE) WWTP
HOLINGER recently coordinated the maintenance of the agitators in the digesters at the MARIN WWTP. After consulting with HOLINGER and the manufacturer of the agitators, the client opted for an overhaul over replacement. Before proceeding, it was essential to confirm that the drive shafts were in good condition and that there were no micro-cracks in the upper part of the shaft. HOLINGER coordinated the safety precautions as well as the cooperation between the Water Treatment Manager and the maintenance company. Lastly, the condition of the concrete on the interior of the towers was assessed.
