Water Recycling from Food Industry Wastewater Using Advanced Technologies: Membranes, Reverse Osmosis, and Reducing Pressure on the Nation's Water Resources

Food industry wastewater, with its high organic load, fats, and suspended solids, poses serious environmental challenges. Advanced treatment technologies such as membrane processes (MF, UF, NF, RO), membrane bioreactors (MBR, An MBR), forward osmosis (FO), and membrane distillation (MD) enable significant reductions in COD, BOD, and TSS, producing water of near-international quality. Recycling water in the food industry reduces environmental pollution, alleviates pressure on national water resources, and supports sustainable development. This study reviews modern technologies, highlights benefit and challenges, and suggests strategies for their application in Iran.
