Abstract

This study aimed to evaluate the use of dregs derived glycerin manufacturing process of cleaning and hygiene products as a co-substrate for additional generating biogas and methane yield. Therefore it was tested dregs of glycerin in the percentage of 2%, 4% and 6% in order to assess what percentage has the best conditions for supplementation. The test was performed in the Laboratory of Bioreactor UNIVATES where prepared 24 reactors containing 600 mL of sludge from wastewater treatment in each, and these were divided into triplicates according to the samples that presented better representation. The reactors were maintained under mesophilic conditions (35°C) with hydraulic retention time of about 56 days. The volume of biogas was controlled by an automated system for measuring and quality of the laboratory scale biogas (CH4) measured from a specific sensor called Advanced Gasmitter, produced by PRONOVA Analysentechnik GmbH & Co. The results showed that the dregs glycerin has further potential for the generation of biogas, and the sample receiving treatment sludge 4% had a higher biogas yield (128.54%) and methane (96.79%) compared to triplicate control and moreover, very high organic loads may affect the process of digestion affecting the quality of the biogas.
