The food and beverage industries use a lot of water and produce a lot of wastewater, which contains a lot of harmful substances. The food and dairy industries are the largest producers of wastewater and effluent, and need a lot of water to process food and beverage products.
Given the volume of wastewater produced by food processing facilities, pretreatment is required, before it may be discharged into the environment or used again. Setting up an ETP, or effluent treatment plant for food and beverage industries, is required for all food and dairy processing enterprises, in order to manage wastewater effectively.
Here, we will look at guidelines provided by the central pollution control board, for effluent treatment plants in food and beverage industries.
Effluent treatment plants in the food and beverage industries
As a by-product of their manufacturing process, the majority of the food and dairy processing sectors produce large amounts of wastewater, also known as effluent. Multiple pollutants and toxins are present in the effluent/wastewater produced. Therefore, an effluent treatment facility can assist in the removal of these contaminants/pollutants.
Characteristics of effluent in food and beverage industries
More water is required for food processing and dairy facilities. Diverse contaminants are present in the wastewater released from the dairy, food, and beverage industries.
High concentrations of suspended solids, total solids, BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), dissolved oxygen, oil and grease, fats, sugar, colour, preservatives, and typically nutrients like nitrogen, ammonia, and phosphate, are found in the effluent or wastewater from the food and dairy industries.

Importance of effective effluent/wastewater treatment method
Without the development and integration of ETP for the food and dairy industries, water-borne pathogens could spread across the ecosystem, causing diseases and the deterioration of water bodies. ETP has shown to be a successful option for wastewater treatment applications, since it considerably treats and decreases the negative effects of wastewater on aquatic ecosystems and humans.
Conclusion
The ideal method for handling wastewater contamination in food and dairy processing facilities, is an effluent treatment plant or ETP. The primary goal of ETP is to create a product that complies with the recommended limits for discharge, and can be safely released into a watercourse or sewer.
Importance of the Food and Beverage industry ETP
1. Practical and effective
2. Easy to use
3. Increased effectiveness in upholding the law
