Anaerobic digester technology is actually fairly basic: cattle manure is pumped into a tank (the Hoffs plan to use a concrete tank, although some digesters use steel tanks) where anaerobic bacteria break down components by feeding on the volatile fatty acids of the manure, creating methane gas.
The minimum concentration of N, P and K was observed in digester-1 (control) and maximum in the digester 4 (70% CD + 30% PW), which had the maximum amount of poultry waste which could be correlated to the fact that Poultry waste contains higher concentration of NPK(3.
The temperature in the digesters in winter is likely to be affected by a range of different factors, but primarily by air temperature, degree of heat exchange between the digester and the air, soil temperature, temperature of inflowing slurry (which is again influenced by air temperature), temperature of the washing water etc.
