Modelling of Biphasic Biogas Production Process from Mixtures of Livestock Manure Using Bi-logistic Function and Modified Gompertz Equation

Christian C. Opurum, Christian O. Nweke, Christopher E. Nwanyanwu & Nkemakolam A. Nwogu · Annual Research & Review in Biology · 2021

In this study, anaerobic digestion (AD) of three livestock manure: (poultry manure (PM), pig dung (PD), and cow dung (CD) was conducted at different mixed ratios under mesophilic (25-35°C) conditions. Two kinetic models, the modified Gompertz and bi-logistic function model were u...
