Use of Ethoxylated Surfactants to Improve Digestate Stability

Abstract:

Thermal or thermocatalytic treatment of sludge resulting from anaerobic digestion in continuous flow installations involves conditioning it in order to homogenise it and stabilize of these suspensions. In this study the digestate resulting in the processing of the algal biomass was conditioned in the presence of potato processing waste. The conditioning was done in several stages. In the first stage, the water content was reduced by controlled evaporation. The partially dried digestate was then ground, and the particle size distribution was determined bydynamic light scattering (DLS) using Nano ZS (Red badge). The digestate suspension was stabilized by adding ethoxylated surfactants and a lipid fraction. The stability of the digestate suspension was determined using a Turbiscan Lab. The stability of the digestate slurry was improved by the addition of lipid fraction and by addition of ethoxylated castor oil.
Keywords:
conditioning of digestate; ethoxylated surfactants; algal biomass
