Dairy Sewage Treatment Plants - Automation Grade: Automatic / Semi-automatic

Dairy Sewage Treatment Plants are specially designed wastewater treatment systems to handle the unique characteristics and high organic load of dairy industry effluents. These plants treat wastewater generated from milk processing and other dairy product manufacturing processes, which typically contain milk solids, fats, proteins, detergents, and nutrients.

*High levels of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).

* Presence of fats, oils, grease, suspended solids, and nutrients like nitrogen and phosphorus.

* Variable pH, ranging from acidic to alkaline due to diverse dairy processes.

* Wastewater volume can be approximately 3-4 liters generated for every liter of milk processed.

1. Screening and Grit Removal :Large solids and grit are removed to protect downstream equipment.

2. Equalization :Balances fluctuations in flow and pollutant concentration.

3. Dissolved Air Flotation (DAF) :Separates fats, oils, greases, and suspended solids efficiently, especially important for cheese and high-fat wastewater.

4. Biological Treatment :Activated Sludge Process (ASP), Moving Bed Biofilm Reactor (MBBR), or Sequencing Batch Reactor (SBR) processes degrade organic matter using aerobic microorganisms, significantly lowering BOD and COD.

5. Chemical Treatment :Coagulation and flocculation may be applied to enhance removal of dissolved solids and nutrients, particularly in high-fat effluents.

6. Tertiary Treatment :Filtration, nutrient removal, and disinfection (UV or chlorination) for enhanced effluent quality suitable for reuse or discharge.

7. Sludge Handling :Thickening, dewatering, and safe disposal of sludge generated during treatment.

*Effectively reduces organic pollutants, fats, and nutrients.

* Complies with environmental discharge regulations.

* Produces treated water suitable for reuse or safe discharge.

* Optimized for variable and complex wastewater typical of dairy operations.

Applications:

* Milk processing plants

* Cheese, yogurt, butter, and ice cream manufacturing units

* Dairy farms and processing facilities

Dairy sewage treatment plants combine physical, chemical, and biological processes to efficiently treat highly polluted dairy effluents, protecting the environment and enabling sustainable water management.
