Wastewater Stabilization Ponds (WSPs)/Oxidation Pond:

It is also called lagoons or stabilization ponds, which are large, shallow ponds designed to treat wastewater through the interaction of sunlight bacteria, and algae.
Algae grow using energy from the sun and carbon dioxide and inorganic compounds released by bacteria in water.
During the process of photosynthesis, the algae release oxygen needed by aerobic bacteria.
The algal populations in the presence of sunlight liberate free oxygen which is again used by the aerobic population to decompose the organic matter present in the sewage.
The action taking place in these ponds is known as bacterial-algal-symbiosis, and it is the symbiotic relationship between bacteria and algae that leads to the stabilization of the organic matter present in the sewage.

Bacteria-Algae Symbiotic Relationship
The symbiotic relationship between bacteria and algae plays a crucial role in reducing Biochemical Oxygen Demand (BOD) in aerobic treatment systems, particularly in aerobic ponds. Here's how this relationship functions and its importance:
Mechanism of BOD Reduction
- Oxygen Generation: Algae perform photosynthesis, producing oxygen as a byproduct. This oxygen is essential for aerobic bacteria to thrive.
- Organic Matter Breakdown: Bacteria utilize the organic matter present in wastewater, breaking it down and consuming oxygen in the process.
- Nutrient Cycling: Algae absorb nutrients released by bacteria during organic matter degradation, promoting a balanced ecosystem within the pond.
Importance of Aerobic Ponds
- Enhanced Degradation: The presence of algae enhances the degradation process, allowing for more efficient BOD reduction compared to systems without this symbiotic relationship.
- Stabilization of Nutrients: The interaction helps stabilize nutrients, preventing algal blooms and maintaining the health of the aquatic environment.
- Improved Water Quality: The overall result is a significant reduction in BOD levels, leading to improved effluent quality suitable for discharge or further treatment.
Conclusion
In summary, the bacteria-algae symbiotic relationship is vital in aerobic ponds for effective BOD reduction. By leveraging the strengths of both organisms, these systems achieve enhanced treatment efficiencies, ultimately contributing to better wastewater management.
