Abstract
A method and system of treating wastewater using primary sludge is disclosed. The treatment system includes a primary separator that separates a carbon source comprising non-solubilized suspended carbon from a source of wastewater. The non-solubilized suspended carbon is solubilized and used as a source of carbon in an aerated anoxic treatment system.
