MBR Ozone System for Water Reuse in Seafood Processing

Pescados Industrializados of Mazatlan, Mexico, a tuna cannery, has installed a new MBR system with down stream ozone treatment. The primary purpose of the MBR is to treat wastewater from the plant to comply with effluent regulations of the Mexican government. 30% of the effluent is further polished using ozone, AC, RO for reuse in the cannery. Ozone water treatment is used in this case to disinfect the water and provide partial oxidation of wastewater components. Removal of micro organisms protects the AC/RO units from biofouling. Ozone has been used extensively in wastewater disinfection because it does not form undesirable disinfection byproducts.
