  • Comparison of methanogenic potential of wood vinegar with gradient . . .
    The threshold value of the inhibitory concentration was obtained at a chemical oxygen demand (COD) of 4 g L in batch AD Three-dimensional electrolysis was adopted to improve the biodegradability of WVWW, and a reduction in the inhibitory rate from 38 2% to 4 9% and an increase in methane production by 53 8% were observed
  • Carbon and energy footprint of electrochemical vinegar wastewater treatment
    In many cases, the pollution hazard is considered as the chemical oxygen demand (COD) from active carbon, and the success of the treatment is measured in terms of how much this specific parameter is reduced
  • Vinegar Engineering: a Bioprocess Perspective
    There are two distinct production methods for fermentation-based vinegars, namely the traditional and submerged methods The traditional method relies on surface culture fermentations, whereby oxygen is obtained from the air
  • Continuous Anaerobic Digestion of Wood Vinegar Wastewater From . . .
    Wood vinegar wastewater (WVWW) is the main by-product of biomass pyrolysis process, which is more suitable to use anaerobic digestion (AD) to achieve energy recovery due to its large amount of organic matter
  • Chemical oxygen demand and its applications
    The COD is the amount of oxygen consumed to chemically oxidize organic water contaminants to inorganic end products The COD is often measured using a strong oxidant (e g potassium dichromate, potassium iodate, potassium permanganate) under acidic conditions
  • Carbon and energy footprint of electrochemical vinegar . . . - ResearchGate
    A novel strategy is presented to monitor total oxygen demand simultaneously at the treatment and energy production sides
  • Theoretical Oxygen Demand Calculation step by step (ThOD)
    In order to calculate the theoretical Oxygen Demand (ThOD), a chemical formula of the component must be determined as well as the reactions that are implied in the biodegradation of the material
  • Chapter 6 Vinegar Engineering - Springer
    The sensitivity of acetic acid bacteria (AAB) to oxygen-deficient conditions (Nieto, 1991; Ebner et al , 1996b) can slow down the process or even render the bacteria unviable unless the medium is efficiently oxygenated on a continuous basis
  • CHEMICAL OXYGEN DEMAND
    Oxygen demand is an important parameter for deter-mining the amount of organic pollution in water The test has its widest application in measuring waste loadings of treatment plants and in evaluating the efficiency of treatment processes
  • Chemical Oxygen Demand - an overview | ScienceDirect Topics
    The chemical oxygen demand (COD) test gives a measure of the total organic content in terms of oxygen by oxidizing all biodegradable and nonbiodegradable organic materials with a strong oxidizing agent such as potassium dichromate
