Abstract: An investigation was completed for nutrient and organic loading removal from vegetable processing wastewater. Vegetable processing wastewater was collected from two industrial partners. The sequencing batch reactor was selected as the treatment technology due to its versatility, with the system HRT chosen as the varying parameter to be tested. It was determined that the optimal conditions for organic loading and nutrient removal for Industrial Partner 1 was 2.5 h of aeration and 1.0 L, which equates to 20% of liquid exchange with a HRT of 30 h, obtaining removal efficiencies of 95%, 79% and 75% for COD, TKN and TP respectively. Confirmation studies were completed with Industrial Partner 2. Similar operational characteristics were used, but different removal efficiencies were obtained, confirming the need to optimize the process for every application. UV disinfection was also used for microbial removal for onsite water reuse.
