Real-Time Implementation for Secure Monitoring of Wastewater Treatment Plants using Internet of Things

The scarcity and demand of water increases rapidly. The varieties of wastewater treatment techniques are adopted to produce the quality water and recycling. Wastewater treatment is the process of removing the contaminants present and to produce it suitable for reuse as well as to save the environment. Water utility systems are susceptible to a variety of natural, infrastructure and man-made hazards. These threats result in contaminating the drinking water and affect the human health as well as environment. It is essential to ensure the smooth functioning of wastewater treatment process and to protect the water utility systems from security attacks. This proposed work is the real-time implementation of embedded system for secure monitoring of wastewater treatment process through the internet. The measure of Dissolved Oxygen (DO) content present in water is essential for marine organisms and fish to breathe. The measure of pH value indicates that the amount of chemicals dissolved in the water and whether organisms are affected by them. The High value of acidity can be deadly to fish and other marine organisms. In this proposed work, the presence of DO content and pH value is detected and sent to the embedded system. The content of dissolved oxygen and pH value is encrypted using embedded system and transmitted across wireless networks. The cipher text is decrypted at the receiver using embedded system. It protects the water security system from unauthorized access and modification of process parameters. It ensures good quality water produced and protects the environment as well as public health.
