Thermochemical pretreatment of meat and bone meal and its effect on methane production

Guangxue WU , Zhenhu HU , Mark G. HEALY , Xinmin ZHAN ,

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 3,   Pages 300-306 doi: 10.1007/s11783-009-0031-6

Abstract: The study on the methane (CH) production potential of pretreated MBM shows that the addition of NaOHat 55°C did not cause the inhibition of the succeeding CH production process.However, CH production was inhibited by the addition of NaOH at 131°C.The CH production potential was in the range of 389 to 503mL CH/g VS MBM and 464 to 555

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 6, doi: 10.1007/s11783-017-0947-1

Abstract: The effects of food to microorganism (F/M) ratio and alcohol ethoxylate (AE) dosage on the methane productionThe results indicated that AE had an inhibitory effect to methane production potential (lag-time dependson the AE dosage) and the negative effect attenuated subsequently and methane production could recoverHowever, the methane production potential was considerably decreased when AE was present in wastewaterproduction activity of sludge and methane production potential.
