The aim of this research was to evaluate the efficiency of an ultrasonication process in combination with METIX-AC technology, a chemical process, for metal removal and dewatering ability, with preservation of fertilizing properties of sewage sludge. Waste activated sludge samples having a total solids concentration of 4 and 20gL −1 , were enriched with Cu and Zn in order to exceed the limiting...
Polycyclic aromatic hydrocarbons (PAHs) have been widely studied due to their presence in all the environmental media and toxicity to life. These molecules are strongly adsorbed on the particulate matters of soils, sludges or sediments because of their strong hydrophobicity which makes them less bioavailability, thus limiting their bioremediation. Different sludge treatment processes were tested to...
