Enhancing biomethanation from dairy waste activated biomass using a novel EGTA mediated microwave disintegration.

A novel approach to explore the impact of calcium specific chelant - Ethylene glycol tetra acetic acid (EGTA) on deflocculation followed by biomass disintegration using microwave (MW) was investigated. In the first phase of the study, the EGTA dosage of 0.012 g/g suspended solids (SS) was found to be optimal for disassociating the biomass.

HO induced cost effective microwave disintegration of dairy waste activated sludge in acidic environment for efficient biomethane generation.

This study aimed to improve the biomethane potential of dairy waste activated sludge (WAS) by HO-acidic pH induced microwave disintegration (HAMW-D) pretreatment approach. The results of HAMW-D compared with the microwave disintegration (MW-D) alone for energy and economic factors. In the two phase disintegration process, the HO concentration of about 0.
