The challenge

The challenge for Sulzer was to prove that the new products are even better than the reliable and proven components previously used.

The solution

Sulzer replaced the old aeration systems of the treatment plant by a proven, longlife, and very efficient aeration system. The old systems were recycled.

I installed the Nopon system in 1992, the new aeration system in 2001, and finally also the new aerators and the Sulzer turbocompressor in 2014. This counts for 25 years of reliable product quality.
