Aerobic Thermophilic Composting of Municipal Solid Waste
Composting is a natural process that turns organic material into a dark rich substance called compost. Aerobic Composting is the creation of compost that depends on bacteria that thrive in an oxygen rich environment. Aerobic bacteria manage the chemical process by converting the inputs (i.e. air, water and carbon and nitrogen rich materials) into heat, carbon dioxide and ammonium. The ammonium ...
متن کاملContinuous Thermophilic
SCHULZE, K. L. (Michigan State University, East Lansing). Continuous thermophilic composting. Appl. MIicrobiol. 10:108-122. 1962.Under complete mixing conditions, aerobic decomposition of mixed organic waste materials has been maintained continuously in the thermophilic phase in a 55-gal rotating drum. Temperatures ranged between 53 and 70 C. Raw material was added daily or every second day in ...
متن کاملEvaluation of thermochemical pretreatment and continuous thermophilic condition in rice straw composting process enhancement.
The effects of thermochemical pretreatment and continuous thermophilic conditions on the composting of a mixture of rice straw residue and cattle manure were investigated using a laboratory-scale composting reactor. Results indicate that the composting period of rice straw can be shortened to less than 10 days by applying alkali pre-treatment and continuous thermophilic composting conditions. T...
متن کاملEffect of seeding during thermophilic composting of sewage sludge.
The effect of seeding on the thermophilic composting of sewage sludge was examined by measuring the changes in CO2 evolution rates and microbial numbers. Although the succession of thermophilic bacteria and thermophilic actinomycetes clearly reflected the effect of seeding, no clear difference was observed in the overall rate of composting or quality of the composted product.
متن کاملIdentification of thermophilic bacteria in solid-waste composting.
The thermophilic microbiota of solid-waste composting, with major emphasis on Bacillus spp., was examined with Trypticase soy broth (BBL Microbiology Systems) with 2% agar as the initial plating medium. Five 4.5-liter laboratory units at 49 to 69 degrees C were fed a mixture of dried table scraps and shredded newspaper. The composting plants treating refuse at Altoona, Pa., and refuse-sludge at...
