Aerobic membrane bioreactors (aMBR) and tertiary reverse-osmosis (RO) filtration of Nutrient-varying Fruit Process Wastewater
Authors: Oppedisano, Joseph Vincent; Singh, Ashutosh; Zytner, Richard G.
Description: As a $2.6 billion annual industry, post-harvest fruit and vegetable processing generates a significant fraction of the total revenue of the food manufacturing industry in Ontario. Fruit processing facilities typically require enormous volumes of water for various operations such as growing, cleaning, rinsing, pressing, water conveyance, and so on. Fruit process wastewater is typically characterized as colloidal, with high organics and nutrient concentrations, and therefore require rigorous treatment methods to meet discharge regulations. One of such technique which has proven to be very effective in producing a potable, disinfected and reusable effluent is aerobic membrane bioreactors (aMBR) followed by tertiary reverse-osmosis (RO) filtration. However, persistent challenges plague the operation of these systems when the process water composition changes. The current study focuses on modifying and optimizing MBR conditions, and determining an ideal microbial consortium, to handle varying influent characteristics.
