    The addition of lime affects the activation of polymer used for dewatering, so it is often suggested that lime stabilization occur after dewatering, which can be more difficult. Lime addition can also cause potential odor issues due to the ammonia produced and is, therefore, not ideal in areas sensitive to odors

    Thickening and dewatering systems can result in significant savings in the cost of biosolids storage, transportation, and end use or disposal. Thickening liquid biosolids from three to six percent total solids will reduce the volume by 50 percent. Thickening is often used before anaerobic digestion or lime stabilization to reduce the capital costs of
