Wastewater treatment plants (WWTPs) use granular activated carbons (GACs) as odor retainers because of their high surface area and porosity. The volatile compounds retained in these GAC beds saturate pores are periodically replaced by pristine GACs, which frequently made from biomass materials such coconut shell. Here, order to recycle exhausted GACs reuse them again adsorbents a WWTP, thermal regeneration wastes is proposed. Aiming achieve more efficient cleaner production, the pros cons...
The following different valorisation processes of banana peel waste (BPW) were evaluated: combustion, production activated carbon/batteries, and biomethanisation. This study showed that the combustion BPW is an interesting option with a zero-carbon cycle. A mass balance demonstrated low concentration sulphurous compounds in flue gases (0.01%, volume), but content structural nitrogen dioxide was remarkable (0.35%). Additionally, should be pre-dried to increase its lower calorific value (LCV)...
Mesophilic anaerobic digestion is a treatment that widely applied for sewage sludge management but has several disadvantages such as low methane yield, poor biodegradability and nutrient imbalance. In this paper, we propose orange peel waste an easily biodegradable co-substrate to improve the viability of process. Sewage were mixed at proportion 70:30 (wet weight), respectively. The stability was maintained within correct parameters throughout process, while yield coefficient 165 L/kg...
The importance of the balance between nutrients in anaerobic digestion process was assessed at laboratory scale. A soluble synthetic solution used as substrate. variable to monitor proportion substrate [C]/[N + P] ratio expressed equivalents each element. blank assay with a constant 53 and three experiments which this modified range 53–1 were performed. An increase concentration nitrogen phosphorus both separately combination observed. most relevant results show loss N biogas form NH 3 for...
Two extraction methods of caffeine and total polyphenols from coffee pulp waste were evaluated using water as solvent: conventional solid-liquid (CSLE) ultrasound-assisted (USAE). A central rotary experimental design was applied in each case, after evaluating the effect substrate:solvent ratio. The highest concentration extractant CSLE found to be 49.9 ± 1.3 mg/L (equivalent 3.7 0.1 g/kg pulp, dry basis (d.b.)), 5.5 min at 96 °C, a ratio 1:10 w/v. In parallel, reached 128.3 4.3 mg gallic...
