Scirpus grosuss in reducing wastewater COD

Introduction

Scirpus grossus, a native aquatic plant, has been studied extensively for its potential in phytoremediation, particularly in reducing chemical oxygen demand (COD) in various types of wastewater. This synthesis aims to consolidate findings from multiple research papers to provide a comprehensive understanding of the effectiveness of S. grossus in reducing COD in wastewater.

Key Insights

High COD Removal Efficiency:
- S. grossus has demonstrated significant potential in reducing COD levels in various wastewater types, achieving reductions up to 88% in sago mill effluent, 66.1% in recycled pulp and paper mill effluent, and 89% in batik wastewater.
- In a study on restaurant liquid waste, S. grossus achieved a COD reduction of 92.35%.
Constructed Wetland Systems:
- Constructed wetlands planted with S. grossus have shown higher COD removal efficiencies compared to control systems without plants. For instance, a subsurface flow system with S. grossus achieved a 66.1% COD removal, outperforming the control system.
- In another study, a constructed wetland with S. grossus removed 100% of COD from pulp and paper mill effluent.
Comparison with Other Plants:
- S. grossus, when used in combination with other plants like Iris pseudacorus, showed enhanced COD removal in batik wastewater, indicating that mixed cultures might be more effective.
- In a study comparing different aquatic plants, S. grossus was found to be the most effective in removing COD from pulp and paper mill effluent, outperforming Azola pinnata and Salvinia molesta.
Operational Parameters:
- The effectiveness of S. grossus in reducing COD can be influenced by operational parameters such as hydraulic retention time (HRT) and wastewater depth. For example, a study found that a 45 cm wastewater depth resulted in lower COD removal efficiency compared to a 35 cm depth.
- The presence of S. grossus in constructed wetlands significantly enhances COD removal compared to non-planted systems, with improvements up to 38.5%.

Conclusion

Scirpus grossus has proven to be highly effective in reducing COD levels in various types of wastewater, including sago mill effluent, recycled pulp and paper mill effluent, batik wastewater, and restaurant liquid waste. Constructed wetlands utilizing S. grossus consistently outperform control systems without plants, and mixed cultures with other plants can further enhance COD removal. Operational parameters such as HRT and wastewater depth also play a crucial role in optimizing the performance of S. grossus in phytoremediation systems. Overall, S. grossus is a promising candidate for the phytoremediation of wastewater with high COD levels.
