Biosolids and sludge are often confused. Sludge includes the untreated solids after wastewater treatment while biosolids are the result of the pre-treatment process at wastewater treatment plants.
Effective pre-treatment digests and decomposes the sludge, destroying bacteria and removing odor while preserving beneficial nutrients. Biosolids are carefully treated and monitored to ensure compliance with all regulatory requirements for health and safety.
