“…OPCs under the optimum conditions mentioned above, were 0.07 US$/(kg color removed) and 0.4 US$/(kg COD removed). These results differ from the results of studies [76][77][78] suggesting that the use of ECF as a process for real printing and packaging wastewater treatment by RSM optimization, could be a feasible technology due to high COD and color removal efficiency and economical viability in terms of operating costs.…”

In this work, electrocoagulation-flotation (ECF) following sedimentation was applied as a printing and packaging wastewater treatment using four Al electrodes with a parallel monopolar configuration. A sedimentation process was applied after the ECF as a post-treatment phase to remove large pollutants. The simultaneous efficacy of the operating parameters initial color content (1,843.44-12,156.56 ADMI), initial pH (3.56-10.44), current density (6.02-22.18 mA/cm 2), and treatment time (5.62-74.38 min) on color and chemical oxygen demand (COD) removal efficiencies were evaluated alongside processing costs. Response surface methodology (RSM) and central composite design (CCD) optimized these key parameters to achieve the highest removal efficiencies and lowest operating costs. Based on the results analyzed by RSM-CCD, using initial color content of 5,576.38 ADMI, initial pH of 7.29, the current density of 18.49 mA/cm 2 , and treatment time of 59.76 min as optimum operational conditions can result in 97.8% and 92.1% for color and COD removal efficiencies, respectively. At these optimum conditions, operating costs (OPCs), including electrodes material and energy consumption, were 0.07 US$/(kg color removed) and 0.4 US$/(kg COD removed). The results confirm ECF-sedimentation as a promising and costeffective tool for the treatment of printing and packaging wastewater.

ÖzEndüstriyel gelişmelere bağlı olarak birçok sanayide ve yüzey sularında kullanılan bor bileşiklerinin konsantrasyonu artmaktadır. Bu nedenle bor giderimi hem insan sağlığı hem de sağlıklı tarım ürünü yetiştirilebilmesi açısından oldukça önemlidir. Bu çalışmada, doğal kabak çekirdeği kabuğunun adsorpsiyon kapasitesi araştırılmıştır. Çalışma için, çözeltinin pH'sının, kabak çekirdeği kabuğu konsantrasyonlarının ve temas süresinin adsorpsiyon sürecine etkisi sabit bir karıştırma hızı (150 rpm) ve sıcaklığı (20 0 C) altında değerlendirilmiştir. Ayrıca, kabak çekirdeği kabuğu, taramalı elektron mikroskobu, X ışını floresansı ve Fourier dönüşümü kızılötesi teknikleri kullanılarak tanımlanmıştır. Elde edilen deneysel veriler kesikli proseste farklı izoterm ve kinetik modelleri kullanılarak analiz edilmiştir. Adsorpsiyon işlemi için optimum koşullar adsorbent dozu = 2 g/L, pH = 5.13 ve temas süresi = 5 dakika olarak belirlenmiştir. Kabak çekirdeği kabuğunun maksimum bor arıtma verimi, ideal şartlarda yaklaşık %88 olarak elde edilmiştir. Langmuir izotermine dayalı maksimum adsorpsiyon kapasitesi 12.61 mg/g şeklinde olup bor elementinin kabak çekirdeği kabuğu üzerine adsorpsiyonu yalancı ikinci derece kinetik ile tanımlanmıştır. Sonuç olarak, bor elementinin, kabak çekirdeği kabuğu kullanılarak sulu çözeltiden etkili bir şekilde çıkarılabileceği kaydedilmiştir.

The present work aims to study chemical oxygen demand (COD), oil-grease, and color removal from vegetable oil wastewater by combined electrocoagulation and activated sludge processes. For this purpose, the sample was pretreated using electrocoagulation by various optimization parameters such as electrode type (Al-Al and Fe-Fe), current density (100-400 A/m 2 ), pH (2-8), and electrolysis time (15-180 min). The results showed that 89.3% of COD, 100% of oil-grease, and 66.2% of color were removed by electrocoagulation under the conditions of 300-A/m 2 current density, pH 2, and 180-min reaction time with Al-Al electrode pairs. Then, the effluent of electrocoagulation was treated by an activated sludge process. The results depicted that the activated sludge process was also effective for vegetable oil wastewater treatment and it enhanced 98.9% COD and 79.2% color removal efficiency. The effluent of the combined process was very clear, and its quality exceeded the direct discharge standard of the water pollution control regulation. The laboratory-scale test results indicate that the combined electrocoagulation and activated sludge process is feasible for the treatment of vegetable oil wastewater. Practitioner points• Vegetable oil wastewater was treated by combination of electrocoagulation and activated sludge processes.• The combined electrocoagulation and activated sludge processes supplied 99.9% COD, 100% oil-grease, and 93.0% color removal efficiency.• The laboratory-scale test results indicate that the combined EC-SBR processes were feasible for the treatment of vegetable oil wastewater.
