Variation Of Total And Soluble Cod Concentration During System The system had good treatment performance, achieving average volatile fatty acid reduction of 53%, total chemical oxygen demand (cod) removal effi ciencies of 84%, soluble cod of 72%, and color of. Download scientific diagram | variation of total and soluble cod concentration during system operation time, phases i and ii. from publication: fouling mechanism in dynamic membrane anaerobic.

Variation Of Total And Soluble Cod Concentrations During System Table 3 shows the evolution, at room temperature, of soluble and total cod of the cattle manure from farm b with time. as can be seen, soluble and total cod de creased with time, the decrease. The optimal s 0 x 0. figure 2 illustrates the our t curves of the respirometry experiments performed under different levels of s 0 x 0, where the variation in the do concentration data was. Indeed, despite a significant variation of total cod concentration in the influent wastewater, the average removal efficiencies were 94.3, 94.6 and 93.0% in period i, period ii and period iii, respectively. concerning soluble cod, the results (fig. 2 b) showed lower removal efficiency compared to total cod. indeed, the average removal. Field and pilot studies showed that approximately 6 32% of the sewage tcod (total cod) can be lost during conveyance (table 1), due to processes including the physical deposition (cod down, mainly gravity sewers), degradation of easily biodegradable components (cod down), an increase of microbial cells (cod up), and hydrolysis in bulk wastewater (no cod change) (fig. 2 a).

Analytical techniques to measure organic matter in water, such as chemical oxygen demand (cod), biochemical oxygen demand (bod5), and total organic carbon (toc) are widely used. modifications have been proposed to make them faster, more sensitive, and more environmentally friendly. the purpose of producing a review over some time is to show the changes made on the standardized methods of each. Previous studies showed that the wastewater had practically no inert soluble cod. the inert soluble cod in the effluent would, therefore, have been produced in the anaerobic reactor by the biomass. significant increases in the effluent cod concentration were observed during the operation of the cumar system at srt lower than 100 days.
