Researchers at India's Indian Institute of Technology (IIT) Guwahati have created an innovative, eco-friendly wastewater treatment system for treating contaminated swine wastewater in remote, rural areas where conventional infrastructure is impractical. The system utilizes taro plants (Colocasia esculenta) and an engineered zig-zag flow design to improve the efficiency of natural wetland treatment.
The technology was developed to address the growing environmental issue of managing nutrient-rich and pathogen-laden piggery wastewater before it contaminates rivers, lakes, and agricultural ecosystems. The study, published in the Journal of Environmental Management, shows how engineering innovation can enhance the performance of natural wetland treatment systems.
The next step for the research team is to scale the laboratory innovation for long-term field validation, aiming to make sustainable, low-cost wastewater treatment accessible to decentralised livestock farming systems across India.
