The Environmental Protection Agency’s (EPA’s) 40 CFR Part 503, Standards for the Use and Disposal of Sewage Sludge, (the Part 503 Rule) defines two types of biosolids with respect to pathogen reduction: Class A and Class B. The difference is defined by the degree of pathogen reduction on the solids.
Oxygen is an important parameter for organic-waste composting, and continuous control of the oxygen in a composting pile may be beneficial. The oxygen consumption rate can be used to measure the degree of biological oxidation and decomposition of organic matter. However, without having a real-time online device to monitor oxygen levels in the composting pile, the adjustment and optimization of
