4) Slurry Storage Drum is use to accommodate the remaining waste from anaerobic process in the digester.
The low energy consumption of the anaerobic process combined with the efficiency of the aerobic method could greatly reduce the environmental harm caused by leachate.
The concentration ofVFAin anaerobic digestion for the solid state of food wastes could rise up to 20 g/L, which is much higher than that in a wastewater anaerobic process [73].
Reactors operating at 55[degrees]C highlighted the instability of the process and the accumulation of volatile fatty acids until the inhibition of the anaerobic process. Both of the operating processes at 37[degrees]C, on the other hand, proved to be very stable with comparable yields.
The purpose of the start-up of the high rate anaerobic process is to cultivate and to retain high concentration of active biomass in the reactor.
Although the retention time is relatively lower compared to anaerobic process, other options for secondary treatment should be consider to accelerate the overall treatment process.
Phenol removal in presence of oxygen is often preferred due to high phenol inhibition on anaerobic processes. However, complete degradation of phenol can happen in anaerobic systems by a well acclimated culture (Moussavi et al.
Therefore, it is usually to be accumulated when the anaerobic digesters are subjected to any shock such as an increase of organic load rate, temperature fluctuation and present of some toxins, even resulting in failure of the anaerobic process (Kaspar and Wuhrmann, 1978; Wong et al., 2009; Shah et al., 2009; Liu et al., 2010).
An aerobic treatment system (ATS) is a small scale sewage treatment system similar to a septic tank system that uses an aerobic process for digestion rather than just the anaerobic process used in septic systems.
Bokashi is a Japanese word meaning 'fermented organic matter' and it offers a simple, yet effective composting system whereby all raw food waste is recycled using an anaerobic process.
In this context, anaerobic process is gaining more attention among the researchers and scientists for the treatment of PCE [9] and [10].
