Anaerobic digestion of process water from hydrothermal treatment processes: a review of inhibitors and detoxification approaches

Bioresources and Bioprocessing, Journal Year: 2024, Volume and Issue: 11(1)

Integrating hydrothermal treatment processes and anaerobic digestion (AD) is promising for maximizing resource recovery from biomass organic waste. The process water generated during contains high concentrations of matter, which can be converted into biogas using AD. However, also various compounds that inhibit the AD process. Fingerprinting these inhibitors identifying suitable mitigation strategies detoxification methods necessary to optimize integration two technologies. By examining existing literature, we were able to: (1) compare methane yields organics removal efficiency water; (2) catalog main found in (3) identify recalcitrant components limiting performance; (4) evaluate approaches detoxify specific degrade components. Common are acids (at concentrations), total ammonia nitrogen (TAN), oxygenated organics, N-heterocyclic compounds. Feedstock composition primary determinant acid TAN formation (carbohydrates-rich protein-rich feedstocks, respectively). In contrast, processing conditions (e.g., temperature, pressure, reaction duration) influence extent Struvite precipitation zeolite adsorption most widely used eliminate inhibition. powdered granular activated carbon ozonation preferred remove toxic substances before treatment. Currently, effective approach reduce toxicity recalcitrance N O-heterocyclic Microaeration methods, disrupt microbiome less than ozone, might more practical nitrifying degrading compounds, but further research this area necessary.

Oil refineries produce annually large quantities of oily sludge and non-biodegradable wastewater during petroleum refining that require adequate management to minimize its environmental impact. The fraction solid the accounts for 25 wt% without treatment their valorization. This work is focused on valorization these particles through transformation into porous materials with enhanced properties potential application in catalytic wet air oxidation (CWAO) a spent caustic refinery wastewater. Hence, dealing both wastes circular approach aligned petrol transformations by 2050. obtained carbonaceous showed improved surface area (260-762 m
