Modelling of the anaerobic semi-continuous co-digestion of sewage sludge and wine distillery wastewater

Abstract

<p>The semi-continuous mesophilic anaerobic co-digestion of sewage sludge and wine distillery wastewater was investigated. Co-digestion with wine distillery wastewater enhances biogas productivity of sludge in 25% and swift the rate-limiting step.</p>

Kinetic Modelling of Anaerobic Co-Digestion of Sewage Sludge and Sherry-Wine Distillery Wastewater: Effect of Substrate Composition in Batch Bioreactor

“…Comparing to the aerobic processes, the anaerobic digestion (AD) treatment presents great advantages, such as low operating costs, a well-known understanding of the available technology, and biogas production during the treatment, which could eventually cover part of the energy requirements in the plant. Recently, the use of SW-DW as cosubstrate in AD of municipal sewage sludge (SS) has been already started studying [3,[7][8][9]. And yet, the addition of co-substrates derived from meat industry, such as chicken manure and poultry manure, are emerging researches [10,11].…”
