“…C/C 0 was always lower than 0,04, which indicates high CBB removing (95,9%). This percentage removal was similar to those found in studies where the hybrid photo-Fenton/adsorption process (Ramírez-Sosa et al, 2013;Almazán-Sánchez et al, 2014;Thankappan et al, 2014). A breakthrough curve usually presents a characteristic S shape, due to the mass transfer forces.…”

“…Hybrid process, such as photo-Fenton followed by adsorption, has been reported efficiently for the complete removal and/or degradation of some wastewater compounds , such as the leather tanning agent syntan (Thankappan et al, 2014); methyl orange (Saldaña-Robles et al, 2014); organic compounds in landfill leachates (Ramírez-Sosa et al, 2013); methyl methacrylate (Almazán-Sánchez et al, 2014).…”

RESUME -Coomassie Brilliant Blue (CBB) is a commonly dye present in the waste of the textile industry. Its use produces waste which must be treated before being discharged into rivers or sewage. Combined processes have been used with efficiency for wastewater treatment. This study aims to evaluate the combined process of photo-Fenton and adsorption for the degradation and removal of the dye CBB in aqueous solution. Initially, the CBB was submitted to photo-Fenton oxidation. Photo-Fenton oxidation degraded 76,9% of the initial CBB concentration, which was not enough to satisfies the Brazilian legislation. The fixedbed adsorption was conducted for 13 hours, and during all this period the outlet concentration was always lower than the breakpoint, being this concentration in compliance with the legislation. The combined photo-Fenton/Fixed-bed adsorption was effective in the CBB removing (at least 95,9%).

“…The reduction of COD during the adsorption process is due to the adsorption of organic matter from the solution (Almazán-Sánchez et al, 2014;Islam et al, 2015). The very high level of bacteria removal using the H2O2/UV treatment has also been documented and demonstrated in other studies (Bhatti et al, 2011;Penru et al, 2012).…”

ABSTRACT. The use of live feed is common in aquaculture processes due to its nutritional advantages, and rotifers comprise one of the most used feeds in finfish aquaculture. However, bacteria present in water used for rotifer culture are a significant source of infection and consequently diseases could cause mortality in fishes. Advanced oxidation process (AOPs) are methods that may be useful to eliminate bacterial infections present in aquaculture wastewater and may allow the reuse of this water. Therefore, the prospect of using different advanced oxidation processes to inactivate Vibrio spp. and total bacteria cultures (TCB) present in this kind of water was evaluated. In particular, UVc/O3/H2O2, UVc/H2O2 and O3/H2O2 and the adsorption process were applied to seawater coming from a fish farming tank. The results obtained were highly promising because it was possible to inactivate 100% of bacteria present in the seawater when UVc/ozone/hydrogen peroxide and UVc/hydrogen peroxide were applied, needing around 20 and 80 min for Vibrio spp. and total culturable bacteria inactivation, respectively. These results are justified due to the strong action between H2O2 in the presence of UVc, which may produce a large amount of hydroxyl radicals. Nevertheless, when ozone/hydrogen peroxide was applied, total inactivation of bacteria did not occur. Also, an interesting relationship between bacteria inactivation and oxide reduction potential of seawater was observed during the process. Rotifers put in water after the treatment did not suffer behavior changes (swimming) and no mortalities were observed.

“…The results are given in mg/l within a few minutes, depending on the method. Analysis with portable UV-vis and UV-vis/NIR spectrophotometers is very simple and despite relatively high detection limits, it is often performed, even for scientific purposes, which can be evidenced by examples of recently published reports (Almazán-Sánchez et al, 2014;Dimitroula et al, 2015;Duguma and Walton, 2014;Liu et al, 2014;Meng et al, 2014). Boiano et al (2000) found no statistically significant differences between the results derived from laboratory and field UV-vis spectrophotometric determinations of airborne hexavalent chromium.…”
