In this study, the effects of organic loading and aeration time on biological treatment of dairy industry wastewater were investigated. The removal efficiencies of the Sequencing Batch Reactor (SBR) increased when the organic loading was decreased and hydraulic retention time (HRT) was increased. The Sequencing Batch Reactor (SBR) was operated in 24 h time cycle and the aeration time of 7 h was sufficient for COD, BOD5 and NH4+‐N removal. The COD parameter in the treated effluent satisfied the discharge limits of Water Pollution Control Regulation (WPCR), when the reactor was operated with dairy industrial wastewater under HRT of 4 h and the organic loading of 0,60 kg BOD5/m3‐d. Therefore, the results showed that higher HRT was required for higher ammonium removal.

Bu çalışmada, süt endüstrisi atıksuyunun Ardışık Kesikli Reaktörde (AKR) arıtımına organik yük ve havalandırma süresinin etkisi araştırılmıştır. Azalan organik yük ve artan hidrolik bekleme süresi (HBS), ardışık kesikli reaktörde KOİ, BOİ5 ve NH4+‐N giderme verimini artırmıştır. Ardışık Kesikli Reaktörde (AKR) 24 saatlik çevrim süresinde, 7 saatlik havalandırma süresinin KOİ, BOİ5 ve NH4+‐N giderme verimi bakımından yeterli olduğu belirlenmiştir. Süt endüstrisi atıksuyunun Ardışık Kesikli Reaktörde (AKR) 4 günlük hidrolik bekleme süresi (HBS) ve 0,60 kg BOİ5/m3‐günlük organik yük altında arıtılması sonucu, KOİ parametresi bakımından Su Kirliliği Kalitesi Yönetmeliğindeki (SKKY) deşarj standardını sağlamıştır. Ancak, daha fazla amonyum giderimi için daha yüksek hidrolik bekleme süresinin (HBS) gerekli olduğu sonucuna varılmıştır.
