The Treatment of Source Separated Food Waste by Mesophilic Anaerobic Digestion System with Leachate Recirculation

Distributed model of solid waste anaerobic digestion: effects of leachate recirculation and pH adjustment.

A distributed model of solid waste digestion in a 1-D bioreactor with leachate recirculation and pH adjustment was developed to analyze the balance between the rates of polymer hydrolysis/acidogenesis and methanogenesis during the anaerobic digestion of municipal solid waste (MSW). The model was calibrated on previously published experimental data generated in 2-L reactors filled with shredded ...

Management of source-separated organic household waste intended for anaerobic digestion Management of source-separated organic household waste intended for anaerobic digestion

Simultaneous treatment of sewage sludge and food waste by the unified high-rate anaerobic digestion system.

This study aimed to evaluate the performance of the unified high-rate anaerobic digestion (UHAD) system treating co-substrate of sewage sludge and food waste. A 24-hr operating sequence consisted of four steps including fill, react, settle, and draw. The effects of co-substrate and organic loading rate (OLR) on the performance were investigated to verify the system applicability. In each OLR, t...
