ABSTRACT Herein, novel nanocomposites based on reduced graphene oxide decorated copper nanoparticles (rGO/CuO) were prepared by the in situ co‐precipitation method. The structural, morphological, and optical characterization of as‐prepared was performed powdered x‐ray diffraction (p‐XRD), scanning electron microscopy (SEM), Fourier‐transform infrared (FTIR), Raman, ultraviolet–visible (UV–Vis) spectroscopy, respectively. exhibited better photocatalytic activity rhodamine B dye with maximum ~94% degradation 120 min a rate constant 0.2353 −1 under optimized conditions. Furthermore, effects solution pH catalyst loading are studied process. Therefore, this state‐of‐the‐art strategy for decoration CuO onto surface rGO nanosheets could be an ideal platform fabricating highly efficient photocatalysts.

Anaerobic digestion (AD) of food waste (FW) is considered an environmentally sustainable process that can divert the disposal FW to landfill and prevent greenhouse gas (GHG) emissions in managing FW. Although several studies have attempted demonstrate AD FW, low methane yields a high incidence instability been reported due rapid generation accumulation volatile fatty acids (VFAs). This paper reviews recent research development with variation composition, such as carbon-to-nitrogen (C/N) ratio and, consequently, effect its physicochemical composition on performance yields. The highlights significance optimizing anaerobic co-digestion (AcoD) carbon-rich substrates garden (GW) and/or addition trace elements strategies improve from review focuses factors effecting feasibility organics (FOGO) substrate for production. also critically analyses prospects enhancement biomethane yield by optimizations impactful parameters. progress related these methods identifying existing limitations efficient FOGO are key findings this review. assesses impact nanotechnology digester. integration FO GO processes has demonstrated enhanced biogas yields, improved stability, better management outcomes compared either alone. Despite advantages, challenges feedstock variability, optimization, need advanced pretreatment remain. Addressing issues through continued technological innovations will be crucial maximizing efficiency scalability systems. Moreover, economic policy frameworks supporting further promote broader adoption.

Performance of a Double-Filter-Medium Tandem Membrane Bioreactor with Low Operating Costs in Domestic Wastewater Treatment

Water, Год журнала: 2024, Номер 16(2), С. 361 - 361

Опубликована: Янв. 22, 2024

To reduce the operating costs of conventional membrane bioreactors (MBRs) and improve stability quality dynamic bioreactor (DMBR) effluent, a homemade inexpensive filter cloth assembly was connected to an up-flow ultra-lightweight-medium (UUF) in lieu expensive modules form double-filter-medium tandem (DT)-MBR. DT-MBR used treat domestic wastewater, its removal efficiencies for chemical oxygen demand, ammonia nitrogen, total phosphorus were similar those aerobic MBR, with average rates 91.1%, 98.4%, 15.1%, 50.7%, respectively. The suspended solid (SS) final effluent 5.6 mg∙L−1, played leading role SS removal, rate 86.0% relatively stable effect little impact via backwashing. activated sludge zeta potential, flocculation sedimentation properties, particle size distribution, microbial compositions, extracellular polymeric substances (EPS), filtration resistance cake layer analyzed; it found that layer, which can also be called (DM), had excellent performance. However, DM theory could not reasonably explain why maintained good even after real reason must related sieving pores. Therefore, concept situ autogenous static (ISASM) proposed. With low quality, is desirable alternative traditional MBR.
