Results of the long-term operation of the system showed that, both reactors provided up to 85% P removal and recovery over wide ranges of aeration times (1.0 4.0 h), hydraulic retention times (HRT) (6.0 15.0 h) and temperatures (0 29.5 °C) for an extended period of 247 d, in which approximate 30% of P was recovered by the struvite accumulation devices.
To cover a broad range of lung aeration, both groups were pooled for each species for the analyses shown in Figures 1 and 2. Fifty-five whole-lung CT scans of mechanically ventilated pigs (range of body weight 27 to 33 kg) were considered in this study.
First, the total rate of aeration is manipulated while employing equal rates of local aeration across the activated sludge tank.
However, the human cohort covered a wide range of lung loss of aeration extension; therefore, the validity of the extrapolation method should not have been affected.
The harvest treatments were designed to create a broad gradient of surface soil disturbance, while the site preparation treatments were done to encompass a range of site drainage and aeration conditions.
The sterile air was constantly supplied at the aeration rate range of 0.5 3 L/min.
The whole-lung CT scans available covered a broad range of lung conditions from normal aeration to gross deaeration and were separated by two independent observers into two groups for each species: normal lungs (normal) and lungs with opacifications (opacified).
As described above, the largest amount of soluble cytochrome c production was observed at pH 10 under low-aeration intensity among the pH range of 7 10 under low- and high-aeration intensities.
As seen in Figure 4, the effect of palm oil on gas holdup in the xanthan solution showed similar trend for all the ranges of agitation and aeration rate studied.
Moreover, an optimized ratio MSW/LTR of 1/1 (w/w), moisture content in the range of 40 55% and moderate to low aeration rate (0.05 0.175 Lair kg−1 mis−1) is recommended to maximise degradation and to obtain a stable product during co-composting of MSW and LTR.
