| Abstract | Open-windrow and mechanical composting of ground refuse and are fuse-sludge mixture were studied. Two mechanical methods, one using the enclosed chamber system and the other a rotary drum, were studied.
The raw refuse was not well segregated and the sludge had a high water content. The composting materials were turned every day for the first
week and then once a week for five weeks. The total composting time was six weeks. Temperatures were recorded before turning and samples
were analyzed for moisture content, volatile solids, carbon, total nitrogen, phosphate (as P2op, and potash (as K2o). In most studies, pasteurizing temperatures were maintained and there were few odor or fly problems. The results obtained indicated that the mechanical methods were most applicable for the disposal of refuse in Bangkok. The major plant nutrients in the finished compost
from refuse and refuse-sludge mixtures varied only slightly. To combine both sewage sludge and refuse into a composting process was advantageous
from the viewpoint that it was economical to dispose two kinds of wastes simultaneously by the same process. |
