What is ETP for beverage industry?
As a bi-product of their manufacturing process, most companies produce wastewater, also known as effluent. The effluent/wastewater created has a wide range of flow and pollution strength, and it contains a number of contaminants/pollutants that can be eliminated using an effluent treatment facility (ETP).
Processing food products in the beverage industry necessitates a bigger volume of water. The strength and properties of waste water discharged by the beverage industry varies. High amounts of total solids, suspended solids, BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), dissolved oxygen, oil and sugar, colour, preservatives, grease, fats, and usually nutrients such as nitrogen, ammonia, and phosphate are found in food and beverage industry effluent.
ETP for the beverage sector is designed and integrated with cutting-edge technology to prevent the spread of water-borne viruses, which can lead to infections and the deterioration of receiving water bodies. ETP has found to be an excellent option for wastewater treatment applications because it considerably decreases the negative effects of effluents on aquatic ecosystems and humans.
The easiest solution to avoid water pollution is to build an effluent treatment plant (ETP) for beverage and food processing enterprises. Its primary goal is to create a product that may be safely released into a watercourse or sewer while staying under the recommended release limits.
Importance of Effluent Treatment Plants in the Beverage Industry:
1. Efficient and effective
2. Easy to use
3. Increased legal compliance
4. Improved industrial image
5. Self-sustaining technology
Stages of ETP Treatment
Preliminary treatment, primary treatment, secondary treatment, and tertiary treatment are the four treatment levels that ETPs typically go through. All of these treatment processes/levels have the capacity to treat food/beverage sector wastewater and reduce its parameters to acceptable levels.
>Pre-treatment or preparatory treatment: It eliminates coarse particles and other big debris found in wastewater as a first treatment step, preventing harm to succeeding treatment units. Coarse screening, grit removal, and, in some situations, breaking big materials into smaller objects are common first treatment activities. The wastewater that has been partially treated is now subjected to the primary treatment level.
>Primary Treatment Level: Physical settling or filtering are used to remove big solids from wastewater at the primary treatment level. Separation of floating material and heavy materials from liquid waste is required. The primary clarifiers are capable of removing 50-60% of suspended particles. During primary sedimentation, oil and grease, organic nitrogen, organic phosphorus, and heavy metals linked with solids are also eliminated.
>Level of secondary treatment: This treatment level's main goal is to remove suspended particles and residual organic waste, which can be accomplished using aerobic and anaerobic processes. In secondary treatment, activated sludge is the most prevalent method. It entails the use of an aeration tank to provide oxygen to microorganisms, resulting in the removal of biodegradable dissolved and colloidal organic materials.
>Tertiary treatment level: This treatment level's goal is to improve effluent quality even further before it's discharged into the receiving environment. It eliminates pollutants that were not eliminated during the previous treatment stages. It uses a disinfection procedure (with chlorine, UV light, and ozone) that leaves no toxic residues in the wastewater.
