Abstract

The amount of boisolids production is increasing due to developing cities and the mitigation of biosolids odorants is a key role to have a successful biosolids land application program. The objective of this study is to investigate the effect of lime stabilization on odor reduction of bio-solids and determine the optimum percentage of lime for each major odor compound and the overall target lime dose in terms of priority and importance of odorants. the Village Creek Water Reclamation Facility (VCWRF) was chosen to supply limed dewatered solids because of having complaints about the odor of biosolids in neighborhood. 5%, 10%, 10%, and 14% lime dosage were respectively identified are the most appropriate lime dose for Carbon disulfide, Dimethyl sulfide, Dimethyl disulfide, and ammonia. Biosolids with 10% lime addition is also identified as the most appropriate lime dose for maximum odor reduction of biosolids in summertime.
