Meat-Processing Wastewater Treatment Using an Anaerobic Membrane Bioreactor (AnMBR)

Fermentation, Год журнала: 2025, Номер 11(2), С. 68 - 68

Опубликована: Фев. 1, 2025

This study explores AnMBR technology as a promising method for treating wastewater from the meat-processing industry by analysing its characteristics and impact under continuous feeding. The solids were retained, utilising an ultrafiltration membrane with pore size of 0.2 µm, efficacy reducing organic load was evaluated. Although COD removal rate decreased 100% at OLR 0.71 g/(L*d) to 73% 2.2 g/(L*d), maximum methane yields achieved highest OLR, 292.9 Nm3/t (COD) 397.8 (VS) per loaded organics 353.1 518.7 removed organics. An analysis microbial community performed end experiment assess effects process substrate on composition. system effectively converts into biogas, maintaining high loss dissolved in permeate, thanks temperature 37 °C salt levels. enables rapid start-up, efficient removal, biogas yields, making it suitable industrial loads, enhancing production, loss. Challenges such phosphate levels present opportunities wider use nutrient recovery water reclamation.

Enhancing Hydrogen and Resource Recovery from Food Waste: A Cascading Approach from Concept to Process

ACS ES&T Engineering, Год журнала: 2025, Номер unknown

Опубликована: Март 30, 2025

Effective management of food waste (FW) is essential for achieving energy self-sufficiency and carbon neutrality in treatment plants (FWTPs). Developing a multitandem efficient FW process crucial performing more recovery at on-site plants. In this study, cascading was developed to treat from generation complete disposal. Compared with the unpretreated (UP-FW), enzymolysis exhibited higher hydrolysis efficiencies FW. Specifically, concentrations glucose, chemical oxygen demand, total organic increased by 259.42%, 49.31%, 33.08%, respectively. The pretreated considerable hydrogen yield 35.81 ± 1.47 mL/g-VS, roughly double that raw used as substrate, which also accompanied 26.52% 19.10% increases ethanol acetate production, recyclable catalyst (FRB800) pyrolyzed fermentation residue showed superior Orange G (OG) removal efficiency better anti-interference ability actual water body. OG could be completely removed within 30 min, dominated singlet oxygen, nonradical pathways, diverse active sites on FRB800. This synchronizes resources degradation pollutants. Overall, these findings indicate an alternative approach disposal possesses significant engineering value broad application prospects FWTPs.

Overcoming the Difficulties of Thermophilic Co-Digestion of Sewage Sludge and Beverage Industry Wastes in the Presence of Zeolite

Energies, Год журнала: 2025, Номер 18(8), С. 2085 - 2085

Опубликована: Апрель 17, 2025

The thermophilic anaerobic bioconversion of various wastes is still challenging, mainly due to process instability and economic profitability. This group includes orange (OWs) brewery spent grain (BSG), the main by-products generated by beverage industry. In this study, a strategy allowing for improving methane production multicomponent co-digestion sewage sludge (SS), OW, BSG was proposed. To overcome difficulties in those wastes, application natural zeolite (Z), i.e., clinoptilolite, experiment performed batch mode at temperature 55 °C. Four experimental series were conducted with differing feedstock compositions, one which control supplied only SS. As compared control, OW BSG, decreased 20% 13%, respectively. turn, significant improvements achieved presence Z. most beneficial results observed reactor SS, Z, characterized yield 420.2 mLCH4/gVS, an increase almost 14% as control. case, significantly improved stability parameters, well inhibitors, limonene phenols, achieved. It also enhanced energy balance 69%,

Effects of Total Solid Content on Anaerobic Fermentation Performance and Biogas Productivity of Tail Vegetables

Fermentation, Год журнала: 2024, Номер 10(8), С. 437 - 437

Опубликована: Авг. 22, 2024

A large amount of vegetable waste generated by farms is currently damaging the environment and public health. Anaerobic fermentation a mature technology that significantly contributes to recovery energy resources from tail vegetables control environmental pollution. However, most wastes have not been utilized due poor performance biogas production, lack optimal solid contents, multiple other reasons. Herein, anaerobic digestion production treated with different total (TS) content was studied using solanaceous leafy as raw materials. Results showed there no acidification in all trials except for treatment TS 6%. The determined be around 20% terms methane efficiency. cumulative per unit volatile solids (VSs) reached 241.7 mL CH4/g VS, about 65% during peak period production. Theoretically, value based on high 1.8 × 1013~4.6 1013 L China. This research provides advice screening specific efficient parameters promote rate fermentation.
