Abstract High total ammonia nitrogen (TAN) inhibits anaerobic digestion (AD) and cannot be completely eliminated by merely enhancing a stage of AD. This study incorporates TAN‐tolerant inoculum into substrates hydrolyzed Rhizopus mixed agents to simultaneously enhance hydrolysis‐acidogenesis‐methanogenesis. The results show 16.46‐fold increase in CH4 production under TAN‐inhibited (6870.97 mg L−1) conditions, even exceeding the AD without TAN 21.10%.

Nitrogen-rich wastewater is a major environmental issue that requires proper treatment before disposal. This comprehensive overview covers biological, physical, and chemical nitrogen removal methods. Simultaneous nitrification–denitrification (SND) most effective in saline water when utilizing both aerobic anoxic conditions with diverse microbial populations for removal. Coupling anammox denitrification could increase rates reduce energy demand. Suspended growth bioreactors effectively treated COD/N ratios demonstrated resilience to low C/N ratios. Moving biofilm exhibit reduced mortality rates, enhanced sludge–liquid separation, increased efficiency, stronger biological structures. SND studies show ≥90% total efficiency (%RETN) setups, Defluviicoccus, Nitrosomonas, Nitrospira as the main communities, while anammox–denitrification achieved %RETN of 77%. Systems using polyvinyl alcohol/sodium alginate medium showed ≥ 75%. Air-lift reflux configurations exhibited high %RENH4, reducing costs minimizing sludge formation. Microwave pretreatment high-frequency electric fields be used improve %RENH4. Adsorption/ion exchange, membrane distillation, ultrafiltration, nanofiltration promise industrial treatment. AOPs sulfate-based oxidants eliminate compounds from wastewater. Tailoring proposed treatments cost-effective removal, optimizing interactions, analyzing techno-economics emerging technologies are crucial.

The concerns over food security and protein scarcity, driven by population increase higher standards of living, have pushed scientists toward finding new sources. A considerable proportion resources agricultural lands are currently dedicated to proteinaceous feed production raise livestock poultry for human consumption. 1st generation microbial (MP) came into the market as land-independent aquaculture. However, MP may be a less sustainable alternative conventional feeds, such soybean meal fishmeal, because this technology requires natural gas synthetic chemicals.

This work evaluated the application of a novel ex-situ vacuum-enhanced anaerobic digestion technology, IntensiCarbTM (IC), which decouples hydraulic retention time (HRT) from solids (SRT), and strips ammonia at neutral pH. Four bench-scale reactors were daily fed with 50/50 (v/v) mix primary sludge (PS) thickened waste-activated (TWAS). Three operated SRT 20d intensification factors (IF = SRT/HRT) 1 (control), 2, 3, while fourth was an IF4 30d. The findings showed that OLR 5.1 ± 0.79 kgCOD/m3/d, 3 times control, COD volatile reduction maintained around 50 %. methanogenic community, most vulnerable ones to high toxicity, dominated by Methanosarcinaceae in IC digesters versus Methanoseata control digester. Specific activity (SMA) biomethanation potential tests (BMP) on digestates indicated 35 %-62 % higher activity, relative control. enhanced performance due combination increased biomass concentration, mitigation toxicity loadings, microbial shift. Reduced digester size organic loading rates (OLR) are two main benefits IC-AD technology. Recovery influent total nitrogen clean water is another promising aspect technology enables running but comparable concentration. recovery reduced N recycle streams, thus minimizing need for side-stream treatment mainstream removal, additional benefits.
