Relieved of these contaminants, the existing treatment system could function perfectly again. Moreover, the new sludge system allowed to discriminate the type of excess sludge for disposal (sludge from the flotation system and biological sewage plant) resulting in a notable reduction in the relevant costs. A period of piloting with a provisional flotation unit preceded this operation. - Tecnologie, Tecnologie depurazione, Chimico-fisico, Tecnologie, Tecnologie depurazione, Chimico-fisico
