Abstract:

In 2014, DC Water will begin operating a new solids processing train at the Blue Plains Advanced Wastewater Treatment Plant consisting of the CAMBI thermal hydrolysis process for solids pretreatment prior to mesophilic anaerobic digestion. DC Water has chosen sequencing batch reactors capable of nitritation-denitritation or deammonification (using the DEMON process) for separate biological treatment of the dewatering sidestream. As part of the sidestream treatment alternatives evaluation, studies were conducted using sidestream generated from an existing CAMBI-digestion plant to confirm the suitability of the DEMON process to treat such a sidestream and to provide insight on design loading rates and related issues. Experimental results reveal a significant reduction in nitrogen conversion rates – rather for the aerobic ammonia oxidizers than for the anammox organisms. Both biomass acclimation and decrease in refractory soluble COD concentrations could alleviate inhibitory impacts.
