Table 2

Lime dosage for upscaled field trial.

Reactor	Initial pH	Sludge wt (kg)	Initial TS; % w/w (wet basis)	Lime dose (kg)	Lime dosage % w/w (dry basis)
Control	6.82	438.80	2.52	0.00	0%
Lime system	7.17	422.50	15.06	22.7	35%

Percentage based on weight of hydrated lime/weight of dry TS of sludge for lime treatment (w/w. TS).
