Abstract Anaerobic digestion of organic waste into methane and carbon dioxide (biogas) is carried out by complex microbial communities. Here, we use full-length 16S rRNA gene sequencing 285 full-scale anaerobic digesters (ADs) to expand our knowledge about diversity function the bacteria archaea in ADs worldwide. The sequences are processed amplicon sequence variants (FL-ASVs) used MiDAS 4 database for wastewater treatment systems, creating 5. expansion increases coverage worldwide, leading...
Anaerobic co-digestion of organic matter improves digester operating characteristics and its performance. In the present work, food waste was collected from institute cafeteria. Two types sludge (before centrifuge after centrifuge) were fluidised bed reactor treating sewage wastewater. Food studied for their physico–chemical characteristics, such as pH, chemical oxygen demand, total solids, volatile ammoniacal nitrogen, nitrogen. A biomethane potential assay carried out to find optimum...
Abstract Anaerobic digestion represents a key biotechnology for the transformation of organic waste into renewable energy (biogas) and relies on complex microbial communities that work in concert to degrade substrates methane carbon dioxide. Here, we sequenced more than half million high-quality, full-length 16S rRNA gene sequences from 285 full-scale anaerobic digesters (ADs) across world expand our knowledge about diversity function bacteria archaea ADs. The were processed amplicon...
The focus of our work is on anaerobic digestion locally available agro wastes like coconut oil cake, cashew apple waste, and grass from lawn cuttings. most productive in terms methane yield, was cake grass. results showed that the initial volatile solids concentration significantly affected biogas production. yield found to be 383 ml CH 4 /g VS 277 added at 4.5 g VS/l. In case production increased with increasing concentrations 199, 250, 256, 284, 332 3, 3.5, 4, 4.5, 5.0 For waste...
Valorization of peanut shells has recently gained prominence in the context thermally converting agricultural waste into biochar, a carbon-rich byproduct with significant potential as soil amendment. The present study delves understanding influence slow (450°C and 500°C) fast (550°C 600°C) pyrolysis temperatures resident time 60 30 minutes, respectively, on physico-chemical properties shell biochar produced low-cost kiln. Results Scanning Electron Microscopy analysis revealed that increased...
Abstract Presence of urine in municipal wastewater is a major problem faced by treatment plants. The adverse effects are noticeable as crystallization equipment and pipelines due to high concentration nitrogen phosphorus. Therefore, improved technologies required that can treat separately at the source their origin then discharge it main stream. In this study, performance microbial fuel cell (MFC) was evaluated with mixed consortia isolated pure cultures (Firmicutes Proteobacter species)...
The main aim of this study is to treat domestic wastewater in a hybrid Vertical Flow Constructed Wetland (VFCW-4.2 m2) and Microalgal Treatment System (MTS-1 m2). objective not only Domestic (DW) but also produce value-added products from microalgal biomass. was initially treated by VFCW the effluent further phycoremediated MTS. Canna indica used for wetland vegetation resident consortium MTS operated at 1 m3/day (HRT-0.25 m3/m2-day, OLR-400 g/m2-day) 0.03 (HRT-0.03 g/m2-day), respectively....
The present study aims at reclamation of secondarily treated water using the microalga Spirulina platensis. objective is to consider wastewater pollutants as nutrients for microalgae cultivation. process led production microalgal biomass that can be used extraction value-added products with potential commercialized. An open raceway pond was a cultivation system. It remove 2.86 g Chemical Oxygen Dmand (COD)/day, 0.12 PO4-P/day, 0.82 NH4-N/day, 0.13 NO3-N/day and 0.88 total nitrogen/day....
Nutrient recovery from source-separated human urine has attracted interest as it is rich in nitrogen and phosphorus that can be utilized fertilizer. However, also contains pharmaceuticals, steroid hormones, etc. their removal crucial they have detrimental effects on the environment health. The current study focuses investigating degradation of pharmaceuticals using a double-chamber microbial fuel cell (MFC). Urine was spiked with four (trimethoprim, lamivudine, levofloxacin, estrone) at...
The development of economically feasible and efficient decentralized onsite treatment septic tank water or blackwater is the need hour. In recent years, Electrochemical oxidation (EO) has been proven to be an alternative technology for use in small-scale, wastewater operations. Recently, electrochemical membrane divided cells reported superior efficiency with regards chemical oxygen demand (COD) removal while producing fewer disinfection by-products. this study, a reduction all major...
This study evaluated the possibility of pretreating selected solid fraction an anaerobic digester treating food waste to lower hydraulic retention time and increase methane production. The investigated effect different pretreatments (thermal, chemical, thermochemical enzymatic) for enhanced production from cottage cheese. most effective were thermal enzymatic. Highest solubilisation COD was observed in pretreatment, followed by thermochemical. In single enzyme systems, lipase at low...
Phosphogypsum (CaSO4) is produced as a waste by-product during phosphoric acid production in the fertilizer industry. Only 15% of worldwide phosphogypsum recycled, while 85% stored vicinity factories huge piles resulting environmental and health hazards. An extensively studied biotransformation to calcium carbonate or calcite (CaCO3) using sulfate reducing bacteria (SRBs) prolonged process results formation extremely hazardous H2S gas. Here we report for first time novel approach CaCO3...
