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 ...

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. ...

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 ...

TORWASH® technology successfully tested on pilot scale at wastewater treatment plant in The Netherlands

TORWASH® is a high temperature treatment of wet biomass streams. This treatment: (1) enables efficient mechanical dewatering of the biomass, (2) enables efficient removal of salts, (3) allows for sufficient biogas production from the effluent because of the mild conditions used, (4) facilitates the recovery of phosphorus and (5) makes the use of additives redundant. ECN part of TNO has ...
