Food Processing is a water-intensive process, and its wastewater byproduct is typically high in volumetric daily flow and also biochemical and chemical oxygen demand (BOD and COD), organics, and nutrients. Consequently, significant on-site treatment and resources are necessary. Wastewater from food processing plants is commonly treated with biological treatment using a two-stage anoxic and aeration process. The plant’s process water is first sent to the anoxic tank for denitrification via nitrate recycle, then followed by a nitrification process in the aeration tank.
