Sentence examples for ferrous concentration from inspiring English sources

The results indicated that the maximum biooxidation rate can be obtained at superficial air velocity of 0.1 m/s and initial ferrous concentration of 6.7 g/L.

It was found that the initial ferrous concentration and the inlet air velocity had a pronounced effect on the ferrous biooxidation rate.

Additionally, the response at optimal levels of pH value and pulp density is found to be independent on the level of initial ferrous concentration.

On the other hand, this system permits the use of a ferrous concentration below the discharge legal limit (2 ppm) being bubbling of air not necessary in that conditions.

Under the optimum conditions, TOC removal increased to 99% in only 45 min, and this system permitted the use of a low ferrous concentration of only 2 mg L−1.

The growth of a mixed culture oxidizing ferrous iron at 75°C was evaluated at various conditions of pH, the presence of sulphur, carbon dioxide enrichment and ferrous and ferric concentrations.

The experimental design methodology was first applied to the chemical oxidation process in order to determine the values of temperature, ferrous ion concentration and hydrogen peroxide concentration that maximize dissolved organic carbon (DOC) and colour removals and increase the effluent's biodegradability.

The variables investigated included the rotation speed (300 1500 rpm), liquid flow rate (10 30 L/h), ferrous ion concentration (0 0.8 mM) and inlet ozone concentration (30 70 mg/L).

Finally, based on the developed kinetic model the degradation process was optimized using central composite design taking as key parameters the ferrous ion concentration and current density.

However, there is no statistically significant interaction between the initial ferrous ion concentration and the pulp density.

Besides, a couple of statistically significant interactions are derived between pH value and pulp density as well as pH value and initial ferrous ion concentration which are precisely interpreted.
