PRELIMINARY INVESTIGATION OF ANAEROBIC CO-DIGESTION POTENTIAL OF PRIMARY AND SECONDARY SEWAGE SLUDGE FRACTIONS WITH FRUIT WASTE
Öz: Co-digestion feasibility of primary (PS) and secondary (SS) sewage sludge fractionsproduced in a municipal wastewater treatment plant (WWTP) was investigated by the mixing of fruitwaste in sequential batch reactors. Toxic threshold level for pH was exceeded as fruit waste digestionproduced a high level of volatile fatty acid (VFA) concentration. Alkali (NaOH) addition provided anoptimum level of pH at 7.95-8.05 and 8.16-8.25 in the co-digestion of PS and SS, respectively, and efficientconversion of VFA to methane gas eliminating VFA accumulation. Buffered co-digestion resulted in 55%(+227-271 mL) and 400% (+501-546 mL) increase in biogas production compared to solely PS and SSstabilization. Fruit waste digestion’s positive effect was obtained at a higher level in SS digestion. pHrather than VFA proved to be the key parameter and NaOH highly effective as an alkali source producingdouble buffering effect by converting carbonic acid produced to bicarbonate alkalinity. High carbohydratecontent of fruit waste exhibited a beneficial potential to neutralize high pH occurring in PS and SSdigestion, thus, minimize free ammonia toxicity balancing hydroxide alkalinity formed from proteinhydrolysis. Optimization of fruit waste loading rate based on pH will enable surplus energy gain andstable operation in sewage sludge and protein-rich wastewater digestion.
Anahtar Kelime: Primer ve Sekonder Arıtma Çamur Fraksiyonlarının Meyve Atığı ile Anaerobik Çoklu Besiyeri Çürütmesi Ön Çalışması
Öz: Kentsel atıksu arıtma tesislerinde (AAT) oluşan primer (PÇ) ve sekonder (SÇ) arıtma çamurlarının meyve atığı ile birlikte anaerobik çürütme çalışması ardışık kesikli reaktörlerde yürütülmüştür. Proseste meyve atığının parçalanması ile yüksek seviyede uçucu yağ asitleri (UYA) oluşarak toksik pH eşiği geçilmiştir. Alkali kaynağı olarak NaOH ilavesi sonrasında pH PÇ ve SÇ için sırasıyla 7.95-8.05 ve 8.16- 8.25 olarak alkali seviyelerde gerçekleşmiş ve UYA’nın etkin metana dönüşümü ile biyogazda sırasıyla %55 (+227-271 mL) ve %400 (+501-546 mL) artış elde edilmiştir. Meyve atığının aynı alkali şartta SÇ için daha yüksek verim ve proses stabilitesi sağladığı gözlenmiştir. Proses için UYA’dan ziyade pH’nın anahtar parametre olduğu belirlenmiştir. NaOH, alkali kaynağı olarak proseste oluşan karbonik asiti bikarbonat alkalinitesine çevirdiği için çift kat etki sağlamıştır. Meyve atığının karbonhidrat içeriği, PÇ ve SÇ çürütmesinde oluşan yüksek pH’nın nötralize edilmesinde faydalı katkı sağlamıştır. Sonuç olarak meyve atığının özellikle SÇ çürütmesinde ilave substrat olarak enerji eldesini arttıracağı belirlenmiştir. Organik yükleme hızının pH bazında optimize edilmesi ile alkali ilavesiz arıtma çamurlarının ve proteinli atıkların çoklu çürütmesinin kararlı işletimle gerçekleştirilmesi de mümkün olacaktır.
