Control of Aeration in Static Pile Composting

Abstract: The systems of aeration control currently available for "Aerated Static Pile" composting are reviewed. These systems are fixed rate, variable rate and automated rate of aeration control. It is concluded that only the automated aeration system can actually cater for the dynamic nature of the composting process. Advantages such as a means of monitoring aeration effectiveness, and an indication of the end of active composting can be incorporated into the system.

“…This system of control linked with a parallel system for supp1ying air in the heating and cooling phases produces the classical curve shown in Figure 1 (b) (Leton and Stentiford, 1990). The heat carrying capacity of the air used in a forced aeration system is not itself responsible for removing the excess heat from the system, this it does indirectly by evaporating moisture from the composting mass.…”

“…Les propriétés isolantes des déchets organiques permettent de stocker une partie de la chaleur générée par l'activité des micro-organismes dans la masse solide et les espaces lacunaires (Barrington et al, 2003). Trois gammes de températures peuvent être définies : 35 à 40°C qui favorise la diversité microbiologique, 45 à 55°C où la vitesse de biodégradation est maximale, et enfin une phase d'hygiénisation du compost qui se produit lorsque la température dépasse 55°C (Stentiford, 1996 ;Mustin, 1987 ;Leton and Stentiford, 1990). e jour entre 7,9 à 8,1.…”

“…To maintain aerobic conditions in a composting mass, aeration must provide the oxygen required by the micro-organisms engaged in breaking down the waste. The provision of air also removes waste gases, excess heat and moisture (Leton and Stentiford, 1990). Through comparison between Beltsville strategy, Rutgers strategy and Leeds strategy (Miller and Finstein, 1985;Stentiford et al, 1985;Pereira-Neto et al, 1987;Leton and Stentiford, 1990;Zhang, 1994b;Stentiford et al, 1996), Zhang (1994b) studied the air flow control strategy of digested sludge batch composting, and built a new control mode.…”

“…COD, VM (Volatile material), starch, cellulose, C/N ratio, temperature, moisture content and oxygen consumption rate, Zhang et al (1988) put forward that the compost was mature when the oxygen consumption rate was about 0.02-0.1DO 2 % min − 1 , varying with the organic matter content. Li and Qian (1990) reviewed some factors of compost Table 6 Different aeration control strategies of composting (Miller and Finstein, 1985;Stentiford et al, 1985;Pereira-Neto et al, 1987;Leton and Stentiford, 1990;Zhang, 1994b;Stentiford et al, 1996) maturity and had a detailed discussion about the oxygen consumption rate as compost matured from the theory and calculation method. Li (1998) recommended lipid as the maturity index for sewage sludge compost after a study on NH 4 + -N, pH, lipid, starch, humus, cellulose, protein, but did not give any quantitative value.…”
