Anaerobic Co-digestion of Water Hyacinth and Sheep Waste

Methane Production by Anaerobic Digestion of Water Hyacinth (eichhornia Crassipes)

Water hyacinth (Eichhornia crassipes) is an aquatic biomass species that exhibits prolific growth in many s s o f h e world (1). It has been suggested as a strong candidate for production of methane because of high biomass yield potential (2). Several studies have been carried out which establish that methane can be produced from water hyacinth under anaerobic digestion conditions (3-6). Both b...

Microwave Pretreatment of Fresh Water Hyacinth (Eichhornia Crassipes) in Batch Anaerobic Digestion Tank (RESEARCH NOTE)

The purpose of the research was to study the effect of microwave power inpretreatment of fresh waterhyacinth on biogas production. The variations of microwave power levels are 240; 400; 560 and 800 W. The variations of microwave heating time are 5; 7 and 9 min. The unpretreated fresh water hyacinth are used as control. The result of research showed that the microwave pretreatment of fresh water...

Anaerobic co-digestion of coffee waste and sewage sludge.

The feasibility of the anaerobic co-digestion of coffee solid waste and sewage sludge was assessed. Five different solid wastes with different chemical properties were studied in mesophilic batch assays, providing basic data on the methane production, reduction of total and volatile solids and hydrolysis rate constant. Most of the wastes had a methane yield of 0.24-0.28 m3 CH4(STP)/kg VS(initia...

Anaerobic Co-digestion of Dairy Manure with Potato Waste

In this study, anaerobic co-digestion of dairy manure (DM) and potato waste (PW) was evaluated to determine the best mixing ratio in terms of biogas and methane (CH4) productions. Batch lab-scale anaerobic co-digestion of DM with PW was conducted at two different temperature ranges [mesophilic (MT) (35-37 oC) and thermophilic (TT) (55-57 oC)]. The tests were conducted at five DM:PW mixing ratio...
