The wastewater flow of almost 1.5 million gal (5.7 million L) is treated each day in this digester, where the COD (chemical oxygen demand) of the wastewater is reduced by over 90 percent. * Odors from the manure storage have been virtually eliminated as a result of the lagoon cover and the wastewater COD reduction. * Greenhouse gases are also significantly reduced, primarily due to the capture of the methane produced, which amounts to 6 tons per day (5.5 metric tons). Because methane has 2 1 times the strength of CO2 as a greenhouse gas, the resulting greenhouse gas reduction amounts to 115 metric tons of CO2 equivalent per day. * The generation of electricity reduces the strain on California's power grid and reduces the need for electricity generation at central power plants.
