  • 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 ...
