Effect of temperature on anaerobic digestion of carbohydrates

Nişasta, glikoz vefrüktoz içeren model atıksularm kesikli kültürde anaerobik giderimi mezofılik ve kış çevre sıcaklığında araştırılmıştır. Mezofilik sıcaklıkta karbonhidrat giderimi daha hızlı gerçekleşmiştir. Ortam sıcaklığında gerçekleştirilen denemelerde uçucu yağ asitleri birikimi daha fazla olmuştur. Sıcaklığın uçucu asit birikimi ve biyogaz verimine etkisi istatistiksel olarak önemli bulunmuştur. Sonuçlar anaerobik arıtımın düşük sıcaklıkta da gerçekleştirilebileceğini göstermektedir.

Sıcaklığın karbonhidrantların anaerobik giderimine etkisi

Anaerobic digestion of model wastewaters containing starch, glucose and fructose was investigated in batch culture at mesophilic and ambient temperature during winter. Carbohydrate utilisation was faster at mesophilic temperature. A higher VFA accumulation was observed at ambient temperature. Effect of temperature on VFA accumulation and biogas yield was found to be statistically significant. The results indicate that anaerobic digestion can also be performed at lower temperatures.
