Summary: The integration of microbial fuel cell (MFC) and recycled utilization of ryegrass litter planted in constructed wetland (CW) can effectively solve wetland plant litter disposal and improve the nitrogen removal of carbon-limited wastewater. The addition of ryegrass litter significantly increased the nitrogen removal rate and promoted microbial growth and denitrification. In MFC-CW, the introduction of MFC not only increased denitrification, but also accelerated biomass hydrolysis and promoted the enrichment and growth of functional microorganisms.

Summary: Poly-ferric-silicate-sulphate (PFSS), synthesized using a co-polymerization process, effectively removes diazo Congo red dye at lower coagulant dosages and a wider pH range. LC-MS analysis reveals a novel degradation pathway of the dye by PFSS, with azo bond cleavage confirmed by UV-Vis and FTIR spectra. Characterization using various techniques confirms PFSS as a polycrystalline material suitable for coagulation-flocculation, making it a highly efficient polymeric coagulant for dye removal from wastewater.

Summary: Anaerobic co-digestion of palm oil mill effluent (POME) and sugarcane vinasse (Vn) with water hyacinth (WH) as co-substrate was conducted in two separate anaerobic bioreactors. The results showed that POME-WH had slightly higher COD and soluble COD reduction compared to Vn-WH. However, VFA reduction was higher in POME-WH. Biogas production was higher in Vn-WH, but methane content was higher in POME-WH. The study also found that growth yield, maximum specific substrate utilization rate, and maximum specific biomass growth rate were higher in POME-WH, while methane yield was higher in Vn-WH.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
