| Summary, etc. | This research was done in three separate phases followed by statistical analysis. In the first phase, WAS was thermochemically pretreated to determine conditions for optimum solubilization and biodegradability. The optimal dosage of Na OH turned out to be in the range of 0.4 to 0.5 gNaOH /gVSS and 0.2 to 0.4 gNaOH /gVSS for solubilization and methanogenesis respectively. In the second phase of the experiments, investigations related to the inhibitory effects were carried out using thermal and thermochemical pretreatment at 115°C, l hr. contact time, and 0.24 gNaOH /gVSS alkali dosage. Reduced methane conversion (20 to 35%) was observed at and beyond FCOD/MVSSseed = 0.4 both in the case of thermal and thermochemically pretreated WAS. Finally, in the third phase Hen Egg Albumin was used to see if, the observed effects of WAS could be explained from the behaviour of its simpler constituents under identical pretreatment conditions. Results indicated very high biodegradability (85 % ) of the protein used. Inhibitory effects on methane conversion were observed both in the case of thermal (12 to 33%) and thermochemical (18 to 33%) with respect to the control possibly, due to formation of nonbiodegradable substances at a high pretreatment temperature (115°C) and also due to the presence of alkali dosage (0.24gNaOH /gVSS) leading to effects observed in the case of WAS. Statistical analysis confirmed the experimental findings. Contributory effects due to. FCOD/MVSSseed, Pretreatment Conditions and Time (days) on methanogenic activity were evaluated using The Three way ANOV A Technique at three levels of Significance (0.01, 0.04, and 0.001). Analysis revealed appreciably high reliability of data obtained especially in the case of WAS. The quantitative trends evaluated using the concept of pure effects due to each of the above explanatory variable supported the experimental findings. |
