Fractality in pH time series of continuous anaerobic bioreactors for tequila vinasses treatment

摘要: pH measurements taken from anaerobic digestion (AD) processes show fluctuations with an apparent random behavior that is usually associated to noise. However, it well-known the AD process carried out on basis of electron interchange donors acceptors. Therefore, such a could be current conditions governing and then, suitable analysis can provide important insights into dynamical operational stability processes. In this work, fractal scaling properties signals different continuous bioreactors (applied treatment tequila vinasses) are analyzed by using R/S analysis. Results indicated dimension directly related key variables (influent COD, VFA biogas production). This findings helpful achieve better insight aspects digesters.
