How does a Food Wastewater Treatment System work? These systems use a combination of processes designed to handle the variable and high-load nature of food industry wastewater. Common steps include grease traps or dissolved air flotation (DAF) for oil and fat removal, biological treatment such as aerobic or anaerobic reactors to reduce COD/BOD, membrane filtration for fine pollutants, and final disinfection for safe discharge. Each stage targets a different type of contaminant to ensure comprehensive purification. https://www.molewater.com/food-wastewater-treatment
