Case study

Rental aerators for a municipal WWTP of 3.900 population equivalent

After reaching the end of it's lifetime cycle, the diffused air aeration system of a municipal waste water treatment plant in Northern Germany needed to be refurbished. After comparing the investment, energy and maintenance costs of different solutions the client came to the conclusion that the HSA direct drive surface aerator of ATB WATER would be the most economic choice. 
To verify this theoretical choice the client decided first to operate and test the aerators on rental base and later to purchase the units and recuperate a percentage of the rent.
