Tata Power to Use Municipal Wastewater
Tata Power, India’s largest integrated private power company commissioned its effluent treatment plant in Jojobera, Jamshedpur. The effluent treatment plant has a capacity of 100 Cu M / Hr and is based on the proven solid–liquid separation technology. The state-of-the-art equipment includes Flash Mixer, Flocculator, Tube Settler, RCC Clarified Water Storage Tank and Dual Media Filter, all of which come with the assurance of quality. The technology allows the plant to have low Operations and Maintenance cost while maintaining excellent product quality. It is expected that the installation of this plantwill result in huge savings of raw water due to the recycling and reuse of waste water. The plant has a standby equipment to tide over faults so as to ensure no disruptions in operations.

The water consumed by power plants is about half of the total annual industrial water consumption in China. Considering some characteristics of wastewater in power plants, the paper presented a new process to treat the wastewater. In the process, wastewater was made centralized treatment utilizing activated sludge firstly, then water purifying agent was put into the wastewater and they were coagulation sedimentation. The wastewater was treated by aeration and disinfection at last. In order to increase the efficiency, the ash conveying water was used as the cogulating aid in the process. The experimental results showed that the presented process was effective. The quality of the wastewater after treated was stabile and the ash conveying water was beneficial to the flocculation promotion. The effluent was well used for the circulating cooling water system. It can be concluded that the wastewater of power plants can be the supplementary water of the circulating cooling water system after appropriate treatment. The engineering practice indicated that the process can reveal the social, economical and environmental benefits and be helpful to the realization of the zero discharge of the power plants.

Use of Degraded Water Sources as Cooling Water in Power Plants
This report is a comprehensive study of the use of three types of degraded water sources as cooling water in power plants: 1) produced water from oil and gas production, 2) agricultural return water from flood irrigation, and 3) treated municipal effluent. The report identifies commercially available technologies to treat degraded water before using as cooling water, including biological treatment and ion exchange systems.
