Abstract

Biodegradability is the major concern for methane generation because complex biocomponents
as key factors for speeding hydrolysis steps. In this study, methane gas
generation potential of paper industry wastewater (PWW) was studied using homogenizer as
mechanical prefragmentation method. Initially, homogenizer was performed by varying
prefragmentation time and rpm. At optimum prefragmentation time (50 min) and rpm
(20000), homogenizer method obtained 3912 mg/L of bio-components extricate during PWW
sample prefragmentation study. Also, maximal of lysification rate (21 %) and suspended
solids (SPD) reduction (18 %) were obtained at 15748 kJ/kg TS homogenizer specific energy.
Then, the prefragmented and control samples were subjected to methane assay. Homogenizer
mediated PWW fragmented sample got higher methane generation (141 mL/g VS) than
control sample (38 mL/g VS). Thus, homogenizer mediated prefragmentation method helps 
to lessen the wastewater generation by enriching methane production with significant
extricate of bio-components at commercial scale.
