Food & Beverage Industry Wastewater Treatment

Introduction

Water is widely used in the food and beverage industry, resulting in a large amount of wastewater. The generated wastewater needs to undergo a series of treatments to meet the requirements of reuse or discharge, in order to reduce costs and protect the environment. Pretreatment system is  typically the most direct and cost-effective solution, with dissolved air flotation system can significantly remove pollutants from wastewater in the food and beverage industry.


Common Pollutants in Food and Beverage Wastewater

Food and beverage wastewater typically contains a variety of pollutants:

  • Biochemical Oxygen Demand (BOD): High levels due to the presence of organic waste, which requires oxygen for decomposition. This is common in food and beverage wastewater due to the presence of sugars, fats, proteins, and other organic materials.

  • Chemical Oxygen Demand (COD): Similar to BOD, COD measures the amount of oxygen required to chemically oxidize organic and inorganic matter in the wastewater.

  • Total Suspended Solids (TSS): These are physical particles suspended in water that can include organic and inorganic materials. High levels of TSS are typical in food and beverage wastewater. It is caused by processing the raw materials and also the cleaning processes.

  • Nutrients: High levels of nitrogen and phosphorus can also be common. These can cause eutrophication in water bodies if not properly treated.

  • Inorganic Contaminants: These include various organics such as PFAS, pesticides, and other chemical mixtures.

  • Pathogens and Antibiotic-Resistant Bacteria: Wastewater can contain bacteria, including those resistant to antibiotics, posing a risk to aquatic life and human health.


The Hazards of Wastewater in the Food&Beverage Industry

1. Excessive heavy metals cause pollution to the environment

The water sources used in the food and beverage industry contain a large amount of heavy metals. Coupled with the long-term use of processing equipment, the abrasion and corrosion of metal materials will also release toxic metals, which results in the generation of wastewater that also contains a large amount of heavy metals, and if it is discharged directly without treatment, it will cause serious pollution to the environment.

2. Wastewater discharge is prone to producing toxic odors

When food and beverage processing plants treat wastewater, they often produce unpleasant odors and mud. These sewage contain decaying substances that will evaporate with the water flow and produce toxic odors, causing adverse effects on surrounding residents and creating air pollution and foul odors that disturb residents.

3. Sewage seeps into water sources, posing a threat to human health

If food and beverage processing plants handle wastewater improperly, its pollutants can seep into the soil, thereby contaminating groundwater and drinking water, posing a threat to human health. If people drink contaminated water, it will have an impact and damage to the organs in the human body, causing diseases.


Food & Beverage Industry Wastewater Treatment


Dissolved air flotation system is an efficient water treatment system suitable for wastewater treatment in the food and beverage industry. According to the different treatment processes, it is divided into primary and secondary wastewater treatment.


What is secondary wastewater treatment?

Secondary wastewater treatment (mainly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or in suspension) from wastewater. Primary wastewater treatment usually takes place before secondary treatment and uses physical phase separation to remove precipitable solids. Secondary wastewater treatment uses biological processes to remove dissolved and suspended organic matter, measured as biochemical oxygen demand (BOD).

There are some other differences between primary and secondary wastewater treatment, including:

  • Primary wastewater treatment generally utilises a physical process by using equipment to break up larger particles, whereas secondary treatment uses biological processes for extraction.

  • The aim of primary wastewater treatment is to remove larger particles, whereas in secondary treatment smaller particles are to be removed.

  • Secondary treatment uses anaerobic or aerobic breakdown processes whereas primary wastewater treatment utilises filtration and sedimentation processes.

Secondary wastewater treatment processes are performed by microorganisms in a managed aerobic or anaerobic process depending on the treatment technology. Secondary wastewater treatment is widely used in sewage treatment and is also applicable to many agricultural and industrial wastewaters.

Conclusion

In the food and beverage industry, wastewater treatment is an important link that cannot be ignored. If discharged directly without treatment, it will cause serious pollution to the environment. Dissolved air flotation can effectively remove pollutants such as suspended solids and oils from wastewater, and reduce BOD and COD. Wastewater management in the food and beverage industry is crucial for environmental protection and regulatory compliance.If you want to know more about food wastewater treatment, please read:Applications-Food Processing Wastewater Treatment
