Technological model on advanced stages of oxidation of wastewater effluent from food industry

The food industry is one of the most resource-demanding branches of industry due to the diverse consumption and array of functional food products that exist globally, which establishes a significant problem of compositions of food industry wastewater. The industry uses large amounts of water for many different functions such as raw materials, sanitary water for food processing, transportation, cooking, dissolving, auxiliary water, cooling, cleaning, etc. Wastewater from the food industry has high amounts of organic matter, but the organic compounds present in the effluent are generally biodegradable, and conventional anaerobic or aerobic biological methods of effluent treatment can be applied. On the other hand, some compounds that are poisonous to a microbial consortium may be present in the effluent because of diverse consumption. The effluent may essentially contain large amounts of suspended solids, nitrogen in several chemical forms, fats, oils, phosphorus, chlorides, and high organic matter. Numerous kinds of wastewater treatments are available such as physical, chemical, and biological and their combinations for the food industry. Advanced oxidation processes (AOP) are a chemical treatment category that is used to oxidize organic compounds found in wastewater, which are complicated to handle biologically, for conversion into simple finished products. This chapter deals with the various technological aspects of advanced oxidation of effluent from the food industry.
