Gac Adsorption

Pink water, explosive-laden wastewater produced in army ammunition plants is often treated using expensive and non-destructive granular activated carbon (GAC) adsorption. This paper compares GAC adsorption and two alternative treatment technologies, anaerobic GAC fluidized bed reactor and zero-valent iron-Fenton process. The bench-scale demonstration of the zero-valent iron-Fenton process with real pink water is reported. The features of three technologies are compared and their advantages and drawbacks are discussed.

Sugarcane Vinasse

This study aimed to produce biohydrogen from sugarcane vinasse in an anaerobic fluidized bed reactor operated at ambient temperature (26-35 °C) with a progressive increase of the organic load rate (OLR) (17-155 kg-COD m-3 d-1) and without influent pH control. Hydraulic retention times (HRT) of 12, 6 and 4 h were applied to increase the OLR. The highest hydrogen yield, hydrogen production rate and percentage of hydrogen in the biogas were obtained in the HRT of 4 h, corresponding to the values of 2.40 mol-H2 mol-1-carbohydrate, 0.33 L-H2 h-1 L-1-reactor, and 33%, respectively. The butyric acid fermentative route was favored in the process. The PCR/DGGE analysis showed that the microbial community structure was modified along operational stages and increasing OLR caused an increase in microbial diversity. The results indicate that biohydrogen production from anaerobic digestion of sugarcane vinasse can be achieved with no alkalization pretreatment.
