Dairy factories mainly face the challenge of high COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) values when treating wastewater with high organic content. The introduction of efficient dehydration equipment (such as food-grade spiral sludge dehydrator) can reduce the difficulty of meeting emission standards in the following ways:
1. High-efficiency solid-liquid separation
Reduce organic matter concentration: Dairy wastewater contains a large amount of lactose, protein and fat particles, and these components can easily form high-concentration sludge. High-efficiency dehydration equipment can significantly reduce suspended solids (SS) and soluble organic matter in wastewater through precision filtration and filter press technology.
Reduce the burden of subsequent treatment: Through solid-liquid separation, the volume of dehydrated sludge is reduced, which reduces the load of subsequent anaerobic or aerobic treatment units and improves treatment efficiency.
2. Improve processing efficiency
Adaptable to high organic load sludge: The equipment can handle sludge with high moisture content and low solid content, helping to quickly reduce the sludge moisture from 90% to 95% to less than 60% and reduce the sludge moisture content.
Continuous automated operation: The equipment supports automated operations, enabling continuous treatment and greatly improving wastewater treatment capacity.
3. Reduce operating costs
Reduce the need for dosing: Compared with traditional plate and frame filter presses or centrifuges, spiral dehydration equipment can operate efficiently without adding a large amount of chemicals, reducing chemical costs.
Low energy consumption: Using a low-speed spiral design, the operating energy consumption is significantly lower than that of centrifugal equipment. At the same time, the maintenance cost of the equipment is low and the service life is long.
4. Support resource utilization
Sludge resource treatment: The dehydrated solid sludge contains organic matter and can be used for composting, biogas fermentation or as animal feed raw materials to further realize resource recycling.
Recycling of clean water: The water produced by the equipment has high clarity, and part of the clean water can be reused in non-production links, such as equipment cleaning or park greening, reducing total emissions.
5. Comply with environmental protection regulations
Standard discharge: After equipment treatment, the COD and BOD indicators of wastewater can be significantly reduced, making it easier for dairy factories to meet national or regional environmental protection discharge standards.
Reduce fines and compliance pressure: Efficient processing capabilities reduce the risk of environmental penalties due to excessive emissions, while improving the factory's social responsibility image.
