“…In the case of Ss this kinetic parameter increased from 0.17 to 0.38/day and from 0.17 to 0.29/day for UD and Tch, respectively. It should be noted that the value for untreated sewage sludge was in the range reported by Zhen et al [19], Zhang et al [29] or Vavilin et al [30]. In turn, for the untreated CdM as compared to the sewage sludge significantly lower hydrolysis reaction rate constant was noted (0.11/day).…”

Abstract.The main objective of this study was to determine the applicability of the selected pretreatment methods as a means of intensification of methane production from sewage sludge as well as its mixtures with grease trap sludge. The addition of the fat rich material to the digester treating sewage sludge resulted in an increased methane yield as well as volatile solids (VS) removal of up to 36% (from 134.75 mL/g VS to 182.84 mL/g VS). Furthermore, thermochemical pretreatment of the co-digestion mixture resulted in an approximately 76% higher methane yield as compared to the untreated sewage sludge. The energy balance showed that, for both materials ultrasonic pretreatment and thermochemical pretreatment has an energy self-sufficiency. All of the tested models fit the experimental data with coefficients of determination higher than 0.96.

Experimental work was carried out for the production of Biogas from poultry waste water. The Poultry waste was collected from farm near Nagercoil at Kanyakumari District. Batch anaerobic digester was designed for 20L capacity. The experiment was carried out for 36 days to monitor the performance. Various parameters like pH, TS, COD have checked for every 24hours. The Production of biogas was measured by water displacement method. The methane content was analyzed by gas chromatography test. Based on the experimental data, kinetics studies have done for various models like Line Weaver-Burk method, Eadie-Hofstee method, Hanes-Woolf method. The Eadie-Hofstee Method has provided better prediction than other method. These results thus indicate that, Eadie-Hofstee Method is best to identify the growth rate, substrate concentration and Limiting Substrate Concentration of the system. The sludge of the poultry wastewater and digester were characterized by SEM analysis. The imaging was done to determine the morphological structure of the sludge and to view the bacterial growth on the surface of the sludge.

“…Aufgrund seiner großen Anfallmengen bieten Fettabscheiderinhalte ein großes Biogaspotenzial (Zhang et al 2014). Die Co-Vergärung von Fettabfäl-len auf Kläranlagen steigert bis zu einer gewissen Zugabemenge den Biogasertrag deutlich, sowohl hinsichtlich der Menge als auch des Methananteils im Biogas (Davidsson et al 2008; Del Mundo und Sutheerawattananonda 2017) und ist daher weit verbreitet (DWA-M380 2009).…”
