SMART SENSOR–INTEGRATED CONSTRUCTED WETLAND SYSTEMS FOR SUSTAINABLE WASTEWATER TREATMENT

Abstract

Constructed wetlands have emerged as an ecofriendly and cost-effective solution for wastewater treatment in urban and rural environments. However, the lack of real-time monitoring limits their operational efficiency and performance optimization. This study presents a smart wastewater treatment framework that integrates constructed wetland systems with IoT-based smart sensors for continuous monitoring and control. Key water quality parameters such as pH, temperature, dissolved oxygen, turbidity, and biochemical oxygen demand are monitored in real time. Sensor data are transmitted to a centralized platform for analysis and performance assessment. Experimental results demonstrate significant improvements in treatment efficiency and system reliability. The proposed approach enhances decision-making, reduces operational costs, and supports sustainable water management. This system is particularly suitable for decentralized wastewater treatment applications in developing regions.
