Distillery Wastes as External Carbon Sources for Denitrification in Municipal Wastewater Treatment Plants
Abstract
In order to improve efficiency of N removal within the existing capacities, the denitrification process can be enhanced by adding external carbon sources. The studies on utilization of various by-products or waste materials as alternative carbon sources for denitrification have been carried out for over 20 years (Sage et al. 2006). Among several commercially available organic compounds (such as methanol, ethanol, acetic acid, glucose), which can be considered effective carbon sources for denitrification, methanol has been most commonly used (Pagilla et al. 2006). The problem of high costs of commercial organic compounds can be overcome if “by chance one does have access to industrial wastewater, for example, brewery wastewater”(Henze et al. 1995). Recently, Gu and Onnis-Hayden (2010) presented a comprehensive literature review that summarized various types of external carbon sources that can be applied for enhancing denitrification. The “alternative” sources comprised raw industrial/agricultural by-products, such as corn syrup, molasses, brewery waste, and other process wastes (such as glycerol from biodiesel production). Makinia et al. (2009) compared the effects of dosing different organic compounds (settled wastewater, and various external “conventional” and “alternative” carbon sources) on the denitrification capability and enhanced biological phosphorus removal (EBPR) interactions using a non-acclimated process biomass from a full-scale facility
