Treatment of seawater for rotifer culture uses applying adsorption and advanced oxidation processes

“…It was observed that DO% and ORP increased during the UV/H2O2/O3 process, this behaviour was also observed by Pedersen & Pedersen (2012), who reported increased values of these parameters when H2O2 was added. The reduction of COD during the adsorption process may be caused by AC's decomposition of H2O2, producing an exchange of a surface hydroxyl group with a hydrogen peroxide anion (Bansal et al, 1988).…”

Removing organic and nitrogen content from a highly saline municipal wastewater reverse osmosis concentrate by UV/H2O2–BAC treatment

“…The results for the BAC alone treatment indicated that the denitrifying bacteria were inhibited more than the nitrifying bacteria by the high salinity of the ROC, as was reported in the study of the nitrification and denitrification of a saline wastewater by Dinçer and Kargi (1999). The slightly lower TN removal by the combined treatment compared with the BAC alone appeared to be due to the lower NO 2 À -N removal which could be related to the potential negative impact of the residual peroxide in the UV/H 2 O 2 -treated ROC on the nitrification and denitrification (Pedersen and Pedersen, 2012). The impact of residual H 2 O 2 on BAC treatment is reported below.…”

Inactivation of Aeromonas hydrophila and Vibrio parahaemolyticus by Curcumin-Mediated Photosensitization and Nanobubble-Ultrasonication Approaches

“…In an intensive aquaculture system including RAS and aquaponics, appropriate microbial control measures can be achieved via water disinfection using chemical or physical (UV-C) approaches. However, chemical application in RAS and aquaponics systems is limited due to many reasons including: lack of approved therapeutants and chemicals; concerns about compromising fish health, worker health, and environmental safety; chemical residue in fish and plants; risk of impairing microbial communities in biofilters which are oxidizing ammonia, and the functionality of the system strongly depends on them [36,38]. Thus, light-curcumin and nanobubbles-ultrasound combinations could be interesting topics for the fresh produce, aquaculture, and algae mass production systems in the photobioreactors, hydroponics, and aquaponics industries as alternative approaches to treat recycling water.…”
