Biodegradable flocculants are rarely used in waste activated sludge (WAS) fermentation. This study introduces an alginate-based biodegradable flocculant (ABF) to enhance both the dewatering and degradation of WAS during its Alginate was identified structural extracellular polymeric substances (St-EPS) WAS, with alginate-producing bacteria comprising ∼4.2% total bacterial population WAS. Owing larger floc size, higher contact angle, lower free energy resulting from Lewis acid-base interaction, addition prepared ABF a network structure significantly improved dewaterability reduced capillary suction time (CST) by 72%. The utilization enriched alginate-degrading consortium (ADC) resulted 35.5% increase methane yield owing hydrolytic activity on St-EPS. Additionally, after 30 day fermentation, CST decreased 62% enhanced St-EPS (74.4%) viscosity + ADC group. genus Bacteroides, 12% ADC, alginate lyase (EC 4.2.2.3) pectate 4.2.2.2 EC 4.2.2.9) degrade polygalacturonate St-EPS, respectively. Therefore, this new elucidates dual roles enhancing degradability These advancements improve production CSTs.
