Statistical Biosolids Odor Predicting Models Using Processing Parameters at Blue Plains Advanced Wastewater Treatment Plant

Abstract

Biosolids are being beneficially recycled for agricultural purposes. Often, however, biosolids odors diminish marketability of biosolids, bring community opposition or, in the worst case, cause the banning of biosolids land application programs. This study aims to develop practical biosolids odor predicting models that can be applied to biosolids management on a daily basis using existing data available at wastewater treatment plant as explanatory variables. A number of biosolids odor predicting models are presented. Biosolids producers can use the models to early detect and notify hauling contractors when malodorous biosolids are anticipated. As a result, malodorous products can be allocated accordingly to appropriate sites in preventing odor complaints from the communities.KEYWORDS: biosolids odor predicting model, sensory and analytical measurement.
