ANZCO Meats Wastewater Treatment Plant
ANZCO Meats is situated in the North Island township of Bulls. Like most meat processing plants, ANZCO’ output doubles during the peak season. Our task was to design and build a biological nitrogen reduction system that used as much of the existing plant as possible.
Benefits
This project demonstrates the cost effectiveness of floating treatment media. The FTM was retrofitted to the existing treatment pond. This saved ANZCO Meats capital expenditure as no additional land or civil construction was required. The plant is able to remain under the same management structure as prior to the upgrade. Also, further tertiary and primary treatment can be incorporated into the design to treat other parameters.
