This study was designed to be a follow up of the WERF Phase III odor study (Biosolids Processing Modifications for Cake Odor Reductions, 03-CTS-9T) odor study. The Phase III study found that iron and aluminum appeared to play important roles in odor generation so some additional data was sought to determine the role these play in determining odor generation from dewatered

12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and …

2. A less established technique involves combined mechanical dewatering and flash-drying systems [20, 21]. By lowering the sludge %DS after the mechanically dewatering stage (that is, at the beginning of the thermal drying stage), one postpones the timing and place in the flash dryer where the sludge goes through its sticky phase.

Iron also had a major impact on dewatering. There was a distinct relationship between the iron content of the raw sludge and polymer dose requirements. As the iron increased, the polymer dose increased following digestion. As suggested in the WERF III report, iron appeared to play a role in TVOSC production from dewatered sludge cakes.

dewatering from a rectangular-shaped excavation area. The pumping rate of each simulated well is varied until the target drawdown (dewatering) level is achieved. The total pumping rates of all wells are then summed to calculate the total dewatering rate for the simulated excavation under the designated duration or time period.
