This study compared the performance of the BTFs at different temperatures. Treatment at highest temperature was not optimal due to the decrease in acetaldehyde solubility with increasing temperature. In addition, seeding with cooking compost is better than seeding with activated sludge at thermophilic conditions since the cooking compost has a wider variety of active thermophilic bacterial seed. However, the performance of the BTFs will still be expected to decrease with the increase of temperature regarding the type of the seeding. Comparing this to a study conducted by Chen 5, it was found that at 20 ºC the elimination capacity value is 28 g m-3 hr-1 at a maximum loading rate of 35 g m-3 hr-13 Whereas, this study showed a bit higher elimination capacity at 38.5 g m-3 hr-1 in the same conditions. Studies conducted by Ryu11, Cox14, and Wei15 explained the thermophilic performance of the BTFs of different compounds such as Trimethylamine, and Ethanol. The studies have observed a high elimination capacity of the treated compound. With acetaldehyde the elimination capacity is lower to the other compounds that were investigated in the previous studies at thermophilic conditions.
