Insight into sludge dewatering by periodate driven directly with Fe(II): Extracellular polymeric substances solubilization and mineralization

Weiwei Bi et al.

Summary: The production of waste activated sludge is increasing due to global population growth. This study utilized Fe2+-catalyzed periodate conditioning to achieve deep sludge dewatering. Radical species oxidation and iron species flocculation played a synergistic role in the mineralization and aggregation of hydrophilic substances in extracellular polymeric substances. The research provides engineers with a new option for optimizing sludge management and enhances understanding of Fe2+/PI conditioning in sludge dewatering.

Dark carbon fixation in intertidal sediments: Controlling factors and driving microorganisms

Bolin Liu et al.

Summary: The study reveals that the rate of dark carbon fixation in intertidal sediments is closely related to the availability of reductive substrates and the sulfide content in sediments. Bacteria harboring the cbbM gene play a dominant role in dark carbon fixation, primarily belonging to the Burkholderia genus. Furthermore, these chemoautotrophic microorganisms may play important roles in the coupled carbon, nitrogen, and sulfur cycles.

Simultaneous recovery of bio-sulfur and bio-methane from sulfate-rich wastewater by a bioelectrocatalysis coupled two-phase anaerobic reactor

Ye Yuan et al.

Summary: The study developed a microbial electrolysis cell coupled with two-phase anaerobic digestion for simultaneous recovery of bio-sulfur and bio-methane from sulfate-rich wastewater. The method efficiently converted sulfides into bio-sulfur in the acidogenic phase and enhanced methanogenesis in the methanogenic phase. The optimization of microbial communities enriched functional consortia capable of sulfides oxidation, hydrogenotrophic methanogenesis, and acetotrophic methanogenesis, leading to a higher bio-methane yield.

Solid-phase denitrification in high salinity and low-temperature wastewater treatment

Fei Han et al.

Summary: This study established an SPD biofilm reactor that achieved over 96% TNRE at low temperature by producing more extracellular polysaccharides, which helped improve nitrogen removal efficiency. Microbial network analysis showed that dominant heterotrophic denitrifiers at lower temperature were replaced by other genera.

Synergistic biological removal of nitrogen and sulfide from saline mariculture wastewater by halophilic consortia

Jinxiao Pang et al.

Summary: The MSADA process utilizing halophilic marine anammox bacteria (MAB) showed high efficiency in removing nitrogen and sulfide from seawater-based wastewater under the optimum S/N ratio of 0.75. The dominant functional microorganisms were identified as Candidatus Scalindua, Sulfurimonas and Sulfurovum, all of which exhibited excellent salt tolerance. Nitrate reductase activity was higher than nitrite reductase activity in the system, allowing for effective reduction of NO3--N to NO2--N for MAB. This coupled process offers a new perspective for the treatment of seawater-based wastewater.
