BIOSOLIDS DEWATERING

Stabilized sludge from the anaerobic digesters is conveyed to holding tanks to await dewatering. The sludge is then dewatered using two Bird centrifuges. Dewatered sludge(BIOSOLIDS), averaging 18 percent total solids, is then sent into the sludge bin where it is stored until our contractor removes it. The sludge cake is then used as a fertilizer on permitted crop land in Pennsylvania and Maryland or used as a soil conditioner for remediating depleted strip mines.
