Sludge treatment − composting | Sludge Processing

May 8, 2020 · Composting is a type of aerobic digestion. Sewage sludge can be combined with other waste materials such as wood chip, straw or green wastes prior to composting to provide a pasteurised product. Around 20−30% of the volatile solids can be converted to carbon dioxide through composting. Composting employs natural mesophilic and thermophilic

sludge composting - principle and conditions governing its use

Composting is controlled fermentation that converts organic matter aerobically and produces stable humic and pre-humic compounds (figure 1). Aeration will only be effective if the medium is air-permeable. Dewatered sludge often has a low porosity; a bulking agent has to be added, usually in the form of a carbonaceous support (20% of the mixture

Is Your Compost Made of Sewage Sludge? | Planet Natural

Jan 14, 2013 · While the EPA has given the use of sewage sludge its blessing some of its own scientists disagree that it’s safe. And for good reason. When you spread sludge on farmland or use a bag of compost you bought at a nursery or home-and-garden supply that’s made with sludge, you’re also spreading contaminants.
