Abstract
A pH treatment and method for extraction of leachable resources and pollutants from sludge. A volume of wastewater sludge is initially dewatered followed by adding pH adjusting agents to the dewatered sludge to remove acid/base-soluble contaminants. The acid/base-soluble contaminants are flushed out or dewatered from the treated product. Treated sludge can then be sent to storage and held for beneficial uses.
