Method for the early estimation of anaerobic degradability of organic substrates

Abstract

A method for the early estimation of anaerobic degradability of organic substrates, starting from initial data acquired from tests measuring BMP (Biochemical Methane Potential). The method consists of: i) calculating the two parameters Band k; ii) comparing the fit of the decreasing trend of Bas Δt varies with a homographic function in the first quadrant; iii) evaluating the goodness of fit between a homographic function and the trend of Bas Δt varies, checking whether the adjusted coefficient of determination R≥R; iv) selecting the value of Bcorresponding to a slope of less than 0.1% that occurs for three consecutive Δt; if no, acquire additional BMP measurements and repeat the previous steps.
