Changing existing aerators with AER-AS aerators

in 3 different WWT plants of Muğla Municipality, Turkey

9 Aqua Turbo® Floating Aerators

 

Challenge

Muğla City Water and Sewage Management (MUSKI) decided to change old aerators at the three different WWT Plants, as part of their investment program.

The main project involved the refurbishment of nine of the existing aerators at the three different WWT plants;

  • Marmaris WWTP,
  • Milas WWTP,
  • Bitez WWTP

Main reasons why revisions were needed;

  • Poor oxygen in the aeration basin,
  • Mixing problem in the aeration basin,
  • Odor problem,
  • The increasing of treatment performance,
  • The reducing of maintenance requirement and cost,
  • Energy saving,

 

Work Carried out

Eta Ekipman made demo studies with 45 kW AER-AS Aqua Turbo® Floating Aerator for two different WWT plants of Muğla Municipality, MUSKI’s control engineers and operators attended these demo studies and experienced the quality and performance of AER-AS aerators.

After the excellent demo studies, MUSKI management have decided to put these revision works in their investment budget and they have made an official tender. Eta Ekipman has won this tender and ordered the aerators with Aquasystems.

Aquasystems manufactured 5 x 55kW and 4 x 18,5kW AER-AS AQUA TURBO® Floating Aerators and made a Factory Acceptance Test for 9 aerators according to EN-12255-15 European standard.
After the test, Aquasystems prepared a test certificate and efficiency certificate for these aerators.

These 9 units were installed at the three different WWT plants, together with Electrical Control Panels with VFD and cabling which were all provided by Eta Ekipman.

  • 3 x AER-AS 5500-24 for the Marmaris WWTP;
  • 2 x AER-AS 5500-24 for the Milas WWTP;
  • 4 x AER-AS 1850-24 for the Bitez WWTP;

All aerators have been connected to their existing SCADA Systems and have automatically adjusted aerator speed according to Oxygen Level in the aeration basin.
 

Outcome

The aerators have been used to support the existing activated sludge plant. The units have been connected to their existing SCADA Systems and adjusted aerator speed has been implemented according to Oxygen Level in the basin.

A manager of Eta Ekipman commented that all the parties involved were extremely pleased with the performance of AQUA TURBO® Floating Aerators during this extensive refurbishment program at the three different WWTP works.
