  • Control of biosolids cake odors using the new biosolids odor reduction selector process

    ABSTRACT Recent introduction of more efficient dewatering devices that generate higher solids concentrations in dewatered cake has been plagued with the non-desirable side effect of more odorous dewatered biosolids. Previous research has shown that the production of volatile organic sulfur compounds (VOSC’s) such as methanethiol (MT), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) ...

  • Impact of Lime Dose and Mixing Quality on Odor Generation by Lime-Stabilized Biosolids

    ABSTRACTOdor generated from lime-stabilized biosolids with various lime doses and mixing regimes was studied during two bench scale experiments over four weeks of storage to determine the correlation between the lime stabilization process and odor strength. For the first bench scale experiment, dewatered solids were mixed with various lime doses (4.5% and 11.7% by wet weight) under various mixing ...

  • Effect of Secondary Aerobic Digestion on Properties of Anaerobic Digested Biosolids

    ABSTRACTIn this study, the performance of sequential anaerobic-aerobic digestion was compared to conventional anaerobic digestion for sludge from the Blue Plains Advanced Wastewater Treatment Plant. Volatile solids removal, polymer conditioning demand for dewatering, and biosolids odor characteristics following anaerobic digestion and sequential anaerobic-aerobic digestion were monitored. Aerobic ...

  • Biosolids Minimization using Integrated Alkaline Sludge Hydrolysis and Biological Nutrient Removal Process

     ABSTRACT This paper presents a pilot-scale evaluation of an integrated approach to sludge management utilizing a combination of biological nutrient removal and biosolids alkaline hydrolysis, as well as attempts to explore the impact of recycled alkaline hydrolysates on sludge yield and anaerobic digestion. The novel concept of converting an existing conventional activated sludge (CAS) ...

  • Alternative Project Delivery California`s First Design-Build-Own-Operate Biosolids Recycling Facility

    ABSTACTThe Sacramento Regional County Sanitation District (District) engaged the private sector for the design, finance, construction, ownership, and 20 year operation and of a Biosolids Recycling Facility (BRF). In early 2005, the BRF began processing solids into heat dried pellets to be beneficially reused. The BRF is located at the Sacramento Regional Wastewater ...

  • Educate, Educate, Educate : Why Colorado Farmers Want New York City Biosolids

     Diverting Wood And Cardboard At Construction Sites Residential home construction in Wisconsin generates 128,000 tons of residuals annually, according to a 1998 study by Camp, Dresser & McKee. Ten builders are participating in a project to demonstrate how easily major components of this waste stream can be recycled.
