This paper describes the application of Pax-18 to control the activated sludge bulking and foaming problems caused by the massive proliferation of Microthrix parvicella in biological reactor of Camp de Turia I wastewater treatment plant (Valencia, Spain). This bacterium aggravates the decanter performance and causes that the operation of all system is distorted. By means of the dosage of this inorganic reagent it is possible to remove the foam and to limit the filaments inside the floes, improving both the decantability of the activated sludge, and the nitrification, suspended solids and organic material removal performance.
