Feasibility of Composting Combinations of Sewage Sludge, Cattle Manure, and Sawdust in a Rotary Drum Reactor
The aim of this paper was to study the effect of five different waste combinations (C/N 15, C/N 20, C/N 25, C/N 30, and control) of sewage sludge coupled with sawdust and cattle manure in a pilot scale rotary drum reactor, during 20 days of the composting process. Our results showed that C/N 30 possesses a higher temperature regime with higher % reduction in moisture content, total organic carb...
متن کاملRadiation Technology for Sewage Sludge Hygienisation
Large amount of sewage sludge is produced in India every day. The sludge is infectious and can spread diseases. It also has essential micro and macro nutrients, especially carbon, useful for soil and crop production. Radiation Technology can be used to hygienise the sludge reliably and affordably and protect health and environment. Addition of useful microorganisms to the hygienised sludge can ...
متن کاملSewage Sludge-derived Adsorbents for H2s Removal
Various methods have been used to dispose of or utilize municipal sewage sludge (1), including incineration, landfilling, road surfacing, conversion to fertilizer, compression into building blocks, and carbonization (1-4). Since 1976 several patents have been issued on carbonization of sewage sludge and various applications of the final materials (4-7). Carbonization of sludge in the presence o...
متن کاملRenewable Energy from Sewage Sludge
At present, the main contributors to waste to energy are municipal solid waste, manufacturing waste and landfill gas. Probably we are all most familiar with the first (MSW), which involves the garbage that the garbage men pick up regularly at our homes and which goes to a landfill, a transfer station, or incinerator. Today we are going to introduce you to something relatively new on the alterna...
متن کاملSewage Sludge Disposal in Switzerland
Sewage sludge was used as fertilizer in agriculture in Switzerland since the begin ning of modern waste water treatment. During the last 40 years several difficulties arose with the agricultural use. The problems with pathogenic germs could be solved with a prepasteurisation. The contamination with heavy metals was reduced during the years but remained a cause for concern. The fear of mad cow d...
