Methodology to determine the specific hydrogenic activity (SHA) of waste sludges
چکیده انگلیسی
Production of hydrogen is influenced by the pH, the concentration of organic matter, and the concentration of sludge. A short-term test is presented in which the specific hydrogenic activity of a waste sludge is calculated in order to quantify its hydrogen production capacity. To determine the ideal conditions for the measurement of SHA was used glucose in concentrations of 1000; 2000; 4000; 8000; 12,000; 16,000; and 20,000 mg O2 L−1; sludge in concentrations of 1250; 2500; 5000; and 7500 mg TVS L−1; and pH adjustments of 5.0; 5.5; 6.0; and 6.5. Given the initial concentration of soluble COD of 12,000 mg O2 L−1, sludge concentration of 2500 mg TVS L−1, and pH of 6.0, the highest SHA obtained was 483 mLH2 g TVS−1 h−1. As to volumetric measurements, given the initial concentration of organic matter of 8000 mg L−1, biomass concentration of 5.000 mg TVS L−1, and pH of 5.5, the volume of produced hydrogen per mass of soluble COD added reached a maximum of 38 mL gCOD−1.
