In the present paper the operation of wastewater treatment plant (WWTP) in the town of Hisarya which includes a biological stage with aeration basins of cyclic type (SBR-method) was studied. The values of the standard indicators of input and output water from the wastewater treatment plant were evaluated. Moreover, the reached effects due to the biological treatment of the wastewater in terms of the COD (95.7%), BOD5 (96.6%), total nitrogen (81.3%), total phosphorus (53.7%) and suspended solids (95.7%) were established. It was concluded that the indexes of the treated water were significantly below the emission limits specified in the discharge permit.

   Bonjour On ne peut faire du traitement -biologique- qu'avec des effluents -biologique- contenant de la matière organique.

   En outre il faut que le milieu -biologique- contienne une flore bactérienne suffisante pour effectuer le travail de biodégradation de la matière organique 

   En outre il faut que le transit entre l'entrée et la sortie de l'effluent en traitement dans le dispositif soit supérieur à 15 jours minimum.

   Après tout dépend de la norme acceptable du rejet par la réglementation en vigueur

   Hello you can do - biological - treatment with - biological - effluent containing organic matter.

   Also should the Middle - biological - contain a sufficient bacterial flora for the job of biodegradation of organic matter also must transit between the entry and the exit of the effluent treatment in the device is greater than 15 days minimum.

   After all depends on the acceptable standard of the rejection by the regulations in force
