A cost analysis of sewage sludge composting for small and mid-scale
2001/10/1/ · A variety of equipment is required for large-scale processing of compost. The most important for windrow system is the turner. Either a standard front-end loader or a specialized compost turner may be employed for this purpose. Compost turners generally are faster and do a better job of mixing than front-end loaders.

Application of a natural cover during sewage sludge composting
Large amounts of sewage sludge are generated in the process of sewage treatment. Sewage treatment and sewage sludge treatment and handling inevitably cause the problem of gas emissions and unpleasant smells. Degradation of organic matter results in the emissions of gases with an unpleasant smell (NH3, H2S, etc.), as well as greenhouse

Reducing H2S production by O2 feedback control during large-scale
Maintaining the O (2) concentration higher than 14% in the pile could reduce H (2)S production. This study suggests that shortening the interval between aeration or aerating continuously to maintain a high O (2) concentration in the pile was an effective strategy for restraining H (2)S production in sewage sludge composting.
