“…10 The wastewater resulting from yeast production has a reported biological oxygen demand (BOD) 5 :COD ratio of 0.69 and a COD concentration of 16 130 mg L −1 . 11 Dilution/pretreatment of wastewater is recommended because high OM concentrations coat the electrode surface, inhibiting electron transfer, and less biodegradable OM has low electrongenerating potential. 12 Pretreatment of substrates in MFCs is particularly beneficial for complex substrates such as sludge and food waste.…”

BACKGROUNDThe high organic load and low biodegradability of the effluent from baker's yeast production limit its use as a substrate in microbial fuel cell (MFC) systems. In this study, baker's yeast production wastewater was used as a substrate in the anode chamber to assess the impact of various pretreatment methods [dilution, microwave (MW), acidic‐thermal, basic‐thermal and ultrasound (US)] on electricity generation and waste treatment. Additionally, azo dye was used as an electron acceptor at the cathode. Power density and coulomb efficiency were evaluated for electricity generation, and chemical oxygen demand (COD) removal and azo dye removal parameters were evaluated for treatability.RESULTSThe maximum power densities obtained were 83.53, 46.54, 19.41, 67.40, 41 and 33 mW m−2 for MW, acidic thermal, alkaline‐thermal and US pretreatments, diluted raw and raw wastewater, respectively. To determine the most suitable pretreatment method, PROMETHEE was performed using the criteria of maximum power density, COD removal, azo dye removal, coulombic efficiency and pretreatment cost. The most suitable method was found to be MW pretreatment. The order of the alternatives was found to be MW > US > acidic/thermal > diluted raw > raw > alkaline/thermal. With the MW pretreatment, 81.34% azo dye removal, 5 g L−1 COD removal, 0.27% coulombic efficiency and €0.284 L−1 pretreatment cost were obtained.CONCLUSIONThe most suitable pretreatment method to be applied to wastewater for the treatment of baker's yeast production wastewater and high energy production was determined as MW using the PROMETHEE approach. © 2023 The Authors.

Türkiye, zeytin üretiminde dünyanın önde gelen ülkelerinden biridir. Toplanan (hasat edilen) zeytinin yaklaşık %25'i sofralık zeytin olarak tüketilmekte, geri kalan %75'i zeytinyağı olarak işlenmektedir. Ülkemizde sofralık zeytin üretiminde farklı hazırlama yöntemleri (İspanyol tipi işlem, çizme ve kırma, salamura tipi, sele tipi, teneke tipi, kalamata tipi, kostikli tip, doğal fermente, vb.) kullanılmaktadır. Hazırlama yöntemine bağlı olarak atıksuyun miktar ve kalitesinde farklılıklar görülmekle birlikte, temelde sofralık zeytin üretimi (SZÜ) işlemlerinden yüksek organik madde, fenolik bileşikler, klorür, alkalinite, çözünmüş katı madde içeren koyu renkli atıksular oluşmaktadır. Bu nedenle, SZÜ atıksularının arıtılması için fiziksel, kimyasal ve biyolojik arıtma süreçlerinin bir arada uygulandığı çözümler önerilmektedir. Türkiye'de SZÜ atıksularının arıtılmasına yönelik teknolojik uygulamalar sınırlıdır. Literatürde, laboratuvar ölçekli bazı çalışmaların sonuçları sunulmaktadır. Ancak, konuyu SZÜ süreçleri ve buna bağlı olarak atıksu kaynakları, atıksu miktarı, atıksu karakterizasyonu ve arıtma alternatifleri şeklinde tüm bileşenleri ile ele alan bir çalışma bulunmamaktadır. Makalede, önce SZÜ süreçleri ile üretimden kaynaklanan atıksuların miktar ve kalitesi hakkında kapsamlı bilgi verilmiştir. Daha sonra SZÜ atıksularının arıtımında öne çıkan yöntemler tanıtılmış, uygun arıtma kombinasyonları irdelenmiştir.
