Enhanced short chain fatty acids production from waste activated sludge conditioning with typical agricultural residues: carbon source composition regulates community functions
BACKGROUND A wide range of value-added by-products can be potentially produced from waste activated sludge (WAS) through anaerobic fermentation, among which short-chain fatty acids (SCFAs) are versatile green chemicals, but the conversion yield of SCFAs is usually constrained by the low carbon-to-nitrogen ratio of the original WAS. Conditioning of the WAS with cellulose-containing agricultural ...
متن کاملCharacterization of biocarbon-source recovery and microbial community shifts from waste activated sludge by conditioning with cornstover: Assessment of cellulosic compositions
Most studies on the production of volatile fatty acids (VFAs) from waste activated sludge (WAS) digestion have focused on operating conditions, pretreatments and characteristic adjustments. Conditioning by extra carbon sources (ECS), normally added in a solid form, has been reported to be an efficient approach. However, this has caused considerable waste of monomeric sugars in the hydrolysate. ...
متن کاملProduction and Use of Short Chain Fatty Acids to Enhance the Via-Nitrite Biological Nutrients Removal from Anaerobic Supernatant
The use of the different external carbon source was investigated to enhance the short-cut nitrificationdenitrification (SCND) and the denitrifying phosphorus removal via nitrite (DPRN) using a sequencing batch reactor (SBR) to treat anaerobic supernatant. The SBR was fed with liquid effluent from the anaerobic co-digestion of waste activated sludge (WAS) and organic fraction of municipal solid ...
متن کاملWhat could the entire cornstover contribute to the enhancement of waste activated sludge acidification? Performance assessment and microbial community analysis
BACKGROUND Volatile fatty acids (VFAs) production from waste activated sludge (WAS) digestion is constrained by unbalanced nutrient composition (low carbon-to-nitrogen ratio). Characteristics conditioning by extra carbon sources, normally in the mixture of raw solid, has been reported to be an efficient approach to enhance WAS acidification. However, little attention has been paid to the contri...
متن کاملBioproduction of Short Chain Fatty Acids in Primary and Excess Sludge Fermentation: Performance and Microbial Community Structures Comparison
The fermentation characteristics of activated biomass from two types of sludge, namely primary sludge (PS) and excess sludge (ES) were compared under three pH conditions (uncontrolled, 4, 10) over a period of 8 days. Results show the highest production of short-chain fatty acids (SCFAs) in PS and ES of 352 ± 7 and 324 ± 13 mg COD/g VSS, respectively at pH 10, on the 2 day in PS fermentation, an...
