The City of Claremont's McLin Creek Wastewater Treatment Plant processes all of its sludge by
composting. Sludge is removed from the biological reactor and conveyed to a aerobic digester for further
stabilization to reduce its volatile solids content and also thicken by decanting. Supernate from the
digester is decanted and returned to the head of the treatment plant. The thickened solids are taken to the
Hickory Regional Compost Facility in Newton, NC for composting. During the composting process, the
sludge is stabilized sufficiently to meet all vector attraction and pathogen reduction requirements. After
drying and curing the compost is distributed to various entities to be used as a soil amendment.
If any additional information is needed, please contact me.
Sincerely,
feri
