473018 Removal of Taste and Odor Compounds with Cactus Mucilage Beads Adsorption and Advance Oxidization: Scale up Applications for Continues Recirculating Aquaculture Systems
Cactus mucilage is a biomaterial that used as food source in some countries and it is renewable, biodegradable, easy access and low cost. Previous research has found mucilage extraction can be used as dispersant in different cases, such as oil spills. Different concentrations and types of mucilage extraction can be combined into Alginate beads that are proved to be effective for removal of GSM and MIB due to adsorption mechanism. Further, modified UVis-TiO2 photo-catalysis oxidization can be combined with the mucilage beads column to keep enhancing the total removal effectiveness of such odor compounds. It is found this combined system can possibly achieve more than 90 percent total removal of MIB and GSM, which may significantly benefit the fish production and market.
In the end, the system will be scaled up and tested in the Mote Marine Laboratory & Aquarium in order to further demonstrate its efficiency in a pilot unit for treating the wastewater from their fish production.
