Treatment of excess sludge
Tons of sludge are leaving wastewater treatment plants each day. Spreading the sludge on agricultural land or in a sanitary landfill is not always a feasible solution. Indeed, the better the water treatment, the more complete the concentration of noxious wastes in the sludge, the “dirtier” the sludge. This is especially the case when untreated industrial waste water is connected to the sewage system. Incineration is a safe way of turning a problem waste into an opportunity.
