Alginate-like exopolysaccharides extracted from different waste sludges exhibit varying physicochemical and material properties.

ABSTRACT: This study examined the influence of different wastewater treatment processes on the physicochemical properties of Alginate-Like Exopolymers (ALE) extracted from waste sludge. Sludge samples were collected from wastewater treatment plants (WWTPs) processing both combined industrial and domestic wastewater, as well as domestic wastewater alone. Among the processes studied, aerobic granular sludge (AGS) produced the highest ALE yield (352 ± 50 mg/g-VS_sludge), significantly exceeding that from membrane bioreactor (170 ± 41 mg/g-VS_sludge) and conventional activated sludge (<130 mg/g-VS_sludge). AGS-derived ALE also had the highest uronic acid content (224 ± 14.5 mg/g-VS_sludge), with mannuronic acids playing a critical role in enhancing hydrogel cohesi
