<p>A method and system for treating sludge in a wastewater facility, comprising the steps of: concentrating the sludge (32) to increase the percent solids content by at least 1.5; selecting a desired homogenizing pressure based on the energy required to disrupt the sludge; disrupting at least a portion of the cellular matter in the concentrated sludge (44) at the desired homogenizing pressure; digesting the disrupted sludge (48) to produce methane gas (52); and converting the methane gas to an available energy source that may be input to the wastewater treatment system, the input energy being substantially the same or greater than the input energy requirement.</p> |
