Abstract:
Although the improved digestibility of primary organic waste subjected to thermal hydrolysis has been studied for decades at industrial scale. Thermal hydrolysis is the mostly used process to enhance biodegradability subjected to alter the chemical, biological and physical property (pH value, BOD, COD, C/N ratio, Volatile solubility, viscosity etc.). Thermal hydrolysis pretreatment plant installs around the world but none currently operated in the India. This study carried out a comparative analysis of the rate of biogas production by anaerobic digestion after two types of thermal hydrolysis process and conventional digester receiving non hydrolyzed waste. Here is mechanical crusher designed for crushing micro level kitchen organic waste. A digester was made for the anaerobic fermentation of hydrolysis sludge. This study revealed that high temperature and pressure organic waste pretreatment mainly improve the production of biogas and their solubility. In this paper we will hydrolysis in three ways. In the First method hydrolysis in the reactor has done by superheated steam at 1500C and 5bar up to 1 hour. The second method hydrolysis in the reactor has done by solar heat at 1000C and 1bar up to 12 hour's. And in the third method crushed organic waste directly pour into the digester. After such type of pretreatment in the lab we compared the pH value, BOD, COD, viscosity and gas production of hydrolyzed waste in the digester. And finally we found that production of gas in following manner, anaerobic digester of hydrolyzed waste (1500C and 5bar) ≥ anaerobic digestion of hydrolyzed waste (1000C and 1bar) ≥ anaerobic digestion of non-hydrolyzed waste.
