Implications of sewage sludge

Sewage sludge has been widely applied to agricultural lands to enhance soil fertility due to its high organic matter and nutrient content. It has been considered as an economically and environmentally sound disposal alternative to landfills and incineration. However, one of the concerns of continued application of sewage sludge is the increased amounts of heavy metals deposited into the soil. ...

Supercritical water oxidation of sewage sludge

ABSTRACT Supercritical water oxidation (SCWO) is an innovative and effective destruction method for organic wastewater and sludge. Several tests of the destruction of sewage sludge by SCWO have been done at two state of the art pilot plants. These units have capacities of 250 kg/h and 1100 kg/h, respectively. The test results show that the technology easily destroys the organic ...

Silver nanoparticles in sewage sludge harmful to soil microorganisms

Recent research has found that silver nanoparticles in sewage sludge, which is used on agricultural land as a fertiliser, can be toxic to soil microorganisms. The researchers calculated that a maximum of 30mg of silver nanoparticles per kilogram of sludge can be applied to land before harm occurs, based on typical application rates in Germany of five tons per hectare of farmland every three ...

Phosphorus recovery from sewage sludge using Aquacritox supercritical water oxidation process

Sewage sludge is a potential source of energy. A kilogram of dried sewage sludge contains approximately 20,000 BTU’s of energy. The challenge with releasing this energy is that sewage sludge, when collected from the bottom of a clarifier is 99% water. In order to release the energy present through gasification, pyrolysis or incineration, the water must be removed before oxidation in air can ...
