WWTP Kazanlak town

The treatment plant treats wastewater from the town of Kazanlak, with an equivalent population of 194 620 p.e. The original design of the WWTP envisaged an aeration system with perforated pipes.

Subsequently, the aeration system was re-designed. The new design incorporated membrane diffusers, type DM-320. This allowed energy savings in the range of 2.8 million kWh/year to be achieved.

Total number of diffusers: 5616;
Diffuser density: 1,15 - 1,79 dif./m2;
Air flow per diffuser: average 3,56 Nm3/h

 
   




 

Reference for WWTP, Kazanlak town

...the aeration system of the activated sludge tank, using membrane diffusers DM-320, operates well and meets the plant requirements. Moreover, the quantity of oxygen delivered exceeds the provision in the design.

Sincerely Yours,
Dipl. eng. Petar Zahariev
Director of Water Company, Municipality of Kazanlak
