The Aperlena Verdict

Open race

No supplier dominates: 12 different companies have won the last 13 comparable contracts from this buyer over 5 years. This is a genuinely open race.

Based on 13 comparable awards by this buyer in this sector over 5 years. Every verdict is recorded before the outcome and graded against the award notice. How we score ourselves.

Summary

Machine-generated summary

The Aachen-Brand wastewater treatment plant is to have its third treatment stage renewed. The work includes replacing the screen upstream of the post-denitrification stage with an automated screen equipped with a cross conveyor. The disc aerators of the clear water nitrification stage must be replaced and upgraded to the current state of the art. Concrete repair work is required on the tanks of the clear water nitrification and filtration stages. In addition, the switchgear serving the third treatment stage must be adapted, and if necessary the incoming power supply line must be renewed. Engineering and planning services are being procured for these measures.
