Biogas Production from Excess Sludge Oxidized with Peracetic Acid (PAA)

Abstract: Human functioning related to living and economic activity involves generating an increasing amount of sewage and sludge, which needs to be subjected to advanced processes of treatment, neutralization, and management. The deterioration in the susceptibility of excess sludge to biochemical decomposition observed under anaerobic conditions leads to the development and application of highly effective methods of wastewater treatment based on the removal of biogenic compounds using activated sludge, with a high degr… Show more

“…Zawieja and Warw ąg [4] aimed to determine the effect of chemical disintegration with peracetic acid on biogas production efficiency using methane fermentation of pretreated sludge. The disintegration of excess sludge before methane fermentation plays an important role by supporting the biochemical decomposition of sludge under anaerobic conditions.…”

“…The disintegration of excess sludge before methane fermentation plays an important role by supporting the biochemical decomposition of sludge under anaerobic conditions. A novelty aspect of the research is the use of a highly effective method of oxidation of excess sludge with peracetic acid (PAA), taking into account the selection of the most favorable treatment conditions to increase the effectiveness of methane fermentation [4]. Sludge pre-treatment with peracetic acid (PAA) increased the soluble chemical oxygen demand and the correlated increase in the concentration of volatile fatty acids, as determined in the filtrate fluid of the pre-treated sludge.…”

“…Pretreatment refers to the treatment of the sludge to increase the availability of the substrate components to microbial enzymes and, as a result, enhance the removal of organics, improve the reaction kinetics, and increase the total biogas generation [11]. The release of trapped organic compounds, an increase in surface area-to-volume ratio, and the hydrolysis of macromolecules, are some of the processes that are known to increase the availability of the substrate to microorganisms [12]. In particular, hydrolysis and β-oxidation are the two processes of utmost importance.…”
