Abstract:
Sewage sludge is dewatered with the aid of lime and then incinerated using high sulfur fuel. During incineration the lime reacts with the sulfur in the fuel and with oxygen to form the solid CaSO. sub. 4 for disposal and thus prevent formation of the pollutant, SO. sub. 2 gas. High sulfur coal may be crushed and used as an additional filter aid or sludge conditioner and then serve as the auxiliary fuel during incineration.
