Influence of mix ratio of potato peel and pig manure on reaction kinetics and methane recovery from anaerobic co-digestion

methane production from anaerobic co-digestion of poultry manure

this study investigated the effect of loading and temperature on anaerobic co-digestion of poultry manure with straw in mesophilic conditions. the study was made at lab-scale using 70l reactor with a hrt of 15 days. during the first phase, different loads of 1.0, 2.0, 2.5, 3.0, 3.5 and 4.0 kg vs/m3.d were studied in order to produce biogas. at load of 3.0 kg vs/ m3.d, vs removal and gas product...

Anaerobic co-digestion of pig manure and algae: impact of intracellular algal products recovery on co-digestion performance.

This paper investigates anaerobic co-digestion of pig manure and algae (Scenedesmus sp.) with and without extraction of intracellular algal co-products, with views towards the development of a biorefinery concept for lipid, protein and/or biogas production. Protein and/or lipids were extracted from Scenedesmus sp. using free nitrous acid pre-treatments and solvent-based Soxhlet extraction, resp...

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...

Kinetics of carbon dioxide, methane and hydrolysis in co-digestion of food and vegetable wastes

Kinetic models which can express the behaviors of hydrolysis and biogas generation more precisely than the conventional models were developed. The developed models were evaluated based on the experimental data of six batch reactors. Anaerobic digestion test was co-digestion of food and vegetable waste with inoculating horse dung by 15% of the total wet weight, at the temperature of 37o</su...
