This study aims to optimize dissolved oxygen levels in treating wastewater generated during the sawmill drying process, using response surface methodology (RSM). The experimental approach, employing three independent variables centrifuge time, centrifuge RPM, and microwave power, evaluates their impact on the effectiveness of wastewater treatment based on dissolved oxygen levels. Parameter ranges are set at 5-20 minutes for centrifuge time, 15-35 for centrifuge RPM, and 100-250 Watts for microwave power. Optimization results reveal the highest dissolved oxygen value with a centrifuge time of 20.00 minutes, centrifuge RPM of 35.00, and microwave power of 100.00 Watts, yielding a maximum value of 9.85 mg/L. ANOVA analysis of the obtained data confirms the compatibility of the proposed model with experimental results (p<0.05), with R2 and R2 (adj) values calculated at 98.53% and 95.90%, respectively. These findings authenticate the reliability of the proposed model and its alignment with experimental data. In addition, the Lack of fit value obtained as a result of ANOVA analysis was found to be 0.075. Ultimately, response surface methodology (RSM) demonstrates potential contributions to optimizing dissolved oxygen in wastewater treatment experiments.

Kereste fabrikasında oluşan atıksuyun gideriminde çözünmüş oksijenin yanıt yüzey metodolojisi (RSM) kullanılarak optimizasyonu

Öz

Bu çalışma, kereste fabrikasındaki kurutma işlemi sırasında oluşan atık suyun arıtılmasında çözünmüş oksijenin yanıt yüzey metodolojisi (RSM) ile optimize edilmesini amaçlamaktadır. Üç bağımsız değişken olan santrifüj süresi, santrifüj RPM ve mikrodalga gücü kullanılarak yapılan deneysel yaklaşım, çözünmüş oksijen seviyelerinin atıksu arıtma etkinliği üzerindeki etkisini değerlendirmektedir. Parametre aralıkları sırasıyla santrifüj süresi 5-20 dakika, santrifüj RPM 15-35 ve mikrodalga gücü 100-250 Watt olarak belirlenmiştir. Optimizasyon sonucunda, en yüksek çözünmüş oksijen değeri santrifüj süresi 20.00 dakika, santrifüj RPM 35.00 ve mikrodalga gücü 100.00 Watt ile belirlenmiştir. Bu parametrelerle en yüksek çözünmüş oksijen değeri 9.85 mg/L bulunmuştur. Elde edilen veriler sonucunda yapılan ANOVA analizi, önerilen modelin deneysel verilerle uyumlu olduğunu (p<0.05) ve R2 ile R2 (adj) değerlerinin sırasıyla %98.53 ve %95.90 olduğunu belirtmektedir. Bu bulgular, önerilen modelin güvenilirliğini ve deneysel sonuçların modelle uyumunu doğrulamaktadır. Sonuç olarak, yanıt yüzey metodolojisi (RSM), atıksulardaki çözünmüş oksijenin optimize edilmesine yönelik yapılan deneylerde katkı sağlayabileceğini göstermektedir.
