The effects of inorganic contaminants on the sterilization process were studied during the 1950s and 1960s 424, 425. At the beginning of the composting process … 266-275. There are three main types of composting systems: Fig. Composting goes … Organisms involved in composting Bacteria are the smallest living organisms and the most numerous in compost; they make up 80 to 90% of the billions of microorganisms typically found in a gram of compost responsible for most of the decomposition and heat generation in compost. Oxygen and Aeration Aerobic composting consumes large amounts of oxygen, particularly during the initial stages. The purpose of this research study was to explore the various factors that influence the utilization of this nursing process. Previous study on effect of temperature on mesophilic digester reports that for each The optimum temperature assisting in the process of putrefaction is 21℃ to 38℃. Investigations carried out by various workers have shown that they are not necessary. aeration) and moisture content. The selection and utilization of these media should be based on certain criteria such as learners’ characteristics, Because composting technology is an economical and effective method to achieve stabilization and innocuity of sewage sludge, composting method is widely used for disposing sludge.

Moisture. If the supply of oxygen is limited, the composting process may turn anaerobic, which is a much slower and odorous process. 4, pp. While many people have a basic understanding of the composting process, few people understand its complexity.
