How is Wastewater managed in the Food Industry?
In terms of production, export, consumption, and future possibilities, India's food processing sector is known to be one of the World's largest. Because of the variety of goods created, as well as the varied fruits, and raw materials used, the wastewater generated by this industry has a wide range of strength and features. The use of many preservatives, perfumes, salts, oil, colour, sugar,and gelatin with other ingredients, which are added according to the production requirements of the goods, contributes to the pollutant load in food processing wastewater or effluent.
Consumption of Water in Food Sector
Fruit and vegetable processing, meat, poultry, and seafood processing, beverage and bottling processing, and dairy processing are the four major categories of food processing. Water is employed as a component, an initial and intermediate cleaning source, a reliable raw material transportation conveyor, and the primary sanitizer for industrial machinery and regions. A significant portion of these waters are potential wastewaters that are necessarily to be treated before being released into the environment.
Characteristics of typical effluent generated and treatment technology recommendations
Moderate to high COD, high BOD, high dissolved and suspended particles, very high nutrient content such as nitrogen, phosphorus, grease and heavy oil define wastewaters from food processing companies. This effluent is amenable to non-chemical biological treatment, which includes anaerobic treatment followed by aerobic treatment, such as the Anaerobic Sludge Blanket Reactor (HUASBR), Hybrid Upflow.
Treatments for the effluent in the Food Industry
For this sector, aerobic biological treatment in the form of high-rate trickling filters or activated sludge plants is usually sufficient. However, the sophisticated biological treatments such as moving bed bioreactor (MBBR) and membrane bioreactor (MBR) are recommended instead of the traditional activated sludge procedure due to the intermittent nature of wastewater discharge or higher shock loadings (ASP).
Using advanced treatment, such as Ultrafiltration (UF) and Reverse Osmosis (RO), the treated effluent can be recycled at a level comparable to food-grade water. Alternatively, a Membrane Bioreactor (MBR) can be used in place of an MBBR to produce industrial-grade water with added R.O. to produce food-grade water.
Measurements of COD and BOD-5 in wastewater from the food industry
Chemical oxygen demand (COD) and biological oxygen demand (BOD-5) measures are routinely used to assess the waste stream's power. This regulates the amount of oxygen required for waste preservation. This is especially useful in the food business because they may be used as a measure of waste and lost product. COD and BOD-5 levels above a certain threshold indicate that waste exists, and when identified at specific areas, they can even help determine the source of the waste, as well as the equipment and chemical programme design.
