Abstract (2. Language): 
Sequencing batch operation was used for nutrient (COD, NH4-N, NO3-N, and PO4-P) removal from synthetic wastewater by using different carbon sources. Operation consisted of anaerobic, anoxic, oxic, anoxic and oxic ( An/ Ax/ Ox/ Ax/ Ox) phases with durations of 2/ 1/ 4.5 / 1.5/ 1.5 hours. Glucose, acetate and a mixture of glucose/acetate were used as carbon source to yield COD/N/P ratio of 100/5/1.5 in the feed. Sludge age was kept constant at 10 days. COD, NH4-N, NO3-N and PO4-P removal efficiencies were maximum at the levels of 96%, 87%, 81% and 90 %, respectively when a mixture (50/50, in terms of COD) of glucose and acetate was used.
Abstract (Original Language): 
Bu çalışmanın amacı, ardışık kesikli işletme ile farklı karbon kaynakları kullanılarak sentetik atıksudan nutrient (KOİ, NH4-N, NO3-N, PO4-P) gideriminde karbon bileşiklerinin etkilerini incelemektir. Ardışık kesikli işletme anaerobik, anoksik, oksik, anoksik ve oksik olmak üzere beş basamaktan oluşmaktadır. Bu basamakların hidrolik alıkonma süreleri sırasıyla 2 / 1/ 4.5/ 1.5/ 1.5 saat olarak sabit tutulmuştur. Giriş atıksuyunda KOİ/N/P oranı 100 / 5/ 1.5 olup, karbon kaynağı olarak glikoz, sodyum asetat ve glikoz/sodyum asetat karışımı kullanılmıştır. Çamur yaşı 10 günde sabit tutulmuştur. Glikoz/sodyum asetat (KOİ olarak 50/50) karışımı kullanıldığında maksimum KOİ, NH4−N, NO3-N ve PO4-P giderme verimleri sırasıyla %96, %87, %81 ve %90 bulunmuştur.
