Abstract | Concerns on global warming and energy costs call for more effective approaches to improve the energy self-sufficiency of large centralized wastewater treatment plants (WWTPs). One such approach is to recover the potential energy available in raw municipal wastewaters. A two-stage process, the AB process, has been suggested for energy-efficient WWTPs. The first stage is a highly loaded biosorption stage (A-stage), and this is followed by a low loaded biological stage (B-stage) ensuring removal of dissolved organics and ammonia. The entrapped organics (energy) in the A-stage could be recovered through biogas generation with the anaerobic digester. This project therefore aims to evaluate the feasibility of the biosorption method as primary step (the A-stage’s mechanism) in the treatment of municipal wastewaters in Singapore. The scope of this research project includes (1) determination of solids content, COD concentration, and calorific value of sludge samples from pilot-plants located in Jurong and Ulu Pandan WRPs, (2) conducting biochemical methane potential (BMP) assay on the sludge samples, and (3) characterization of centrate of the BMP reactors. The BMP assay was performed to determine anaerobic biodegradability of the sorption-enhanced primary sludge (the A-stage’s sludge) in comparison with the conventional activated sludge (the B-stage’s sludge). The results would then serve as preliminary information for designing anaerobic digestion (AD) system and optimizing biogas production. The analysis of sludge samples collected from Jurong WRP was completed in the first part of the project (August 2013 to March 2014), while the second part of the project (March 2014 to August 2015) focused on the samples from the Integrated Validation Plant (IVP) located in Ulu Pandan WRP. |
