Abstract:
Provided are wastewater treatment processes that involves struvite precipitation and a microbial fuel cell for the recovery of nutrients and energy from a digester effluent.

Claim (Index 9):
A wastewater treatment process comprising:\n digesting waste activated sludge in an anaerobic digester to generate an digester effluent; centrifuging the digester effluent to produce a liquid influent; forming struvite precipitation from the liquid influent to thereby generate a first liquid effluent, wherein the phosphorus concentration in the first liquid effluent is reduced compared to the phosphorus concentration in the liquid influent; providing the first liquid effluent to a fixed-film nitrification reactor to convert ammonium in the first liquid effluent to nitrate or nitrite thereby generating a second liquid effluent comprising nitrate, nitrite, or a mixture thereof; and providing the second liquid effluent and an influent primary wastewater or other electron-donating organic substrate to a microbial fuel cell, wherein the microbial fuel cell comprises an anodic chamber for organic decomposition and a cathodic chamber for denitritation, denitrification, or both, wherein the second liquid effluent is provided to the cathodic chamber and the influent primary wastewater or other electron-donating organic substrate is provided to the anodic chamber, whereby the microbial fuel cell generates energy and a third liquid effluent is generated having reduced amounts of nitrogen and phosphorus compared to the waste activated sludge.
