  • 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 ...

  • Harmful polycyclic aromatic hydrocarbons removed from soil using wastewater sludge and polyacrylamide

    Wastewater sludge is widely used to remove toxic polycyclic aromatic hydrocarbons (PAHs) from soil, and yet the mechanisms underlying this process remain unclear. A new study reveals the extent of PAH removal following different treatments, and could provide a useful resource for those looking to diminish the effects that these pollutants have both on people and on the environment. PAHs have been ...
