    The United Nations predicts that by the year 2025, two-thirds of the world’s population will face water scarcity. Further, the planet would have well over eight billion people, the majority of whom would live in developing countries, where more than 80% of those are already experiencing water scarcity. Therefore, there is an urgent need for wastewater recycling to help solve issues of scarcity and to facilitate better management of generated wastewater. Water recycling includes reuse and treatment of municipal wastewater, which could be a sustainable approach for environmental sustainability and could also help to offset the increasing water demands for irrigation and industrial and other needs. Currently, water and wastewater treatment facilities consume large amounts of energy that are mainly generated through the use of fossil fuels. Solar Powered Wastewater Recycling examines how solar power can be implemented as an integrated approach whereby all the energy needs of the water and wastewater sector could be supplemented by renewable technologies, and in which a synergy can be developed between water and energy.

    Dr. Arun Kumar is currently working in the field of microalgae and their applications in bioremediation and sustainable environment. Dr. Kumar has published various research and review papers in reputed journals like Frontiers in Microbiology, Frontiers in Biosciences and Environment and Sustainability Indicators in the area of microalgal bioremediation, biofuels and bioproducts production from microalgae. He also published an international book Microalgae in Wastewater Remediation from CRC Press, Taylor & Francis Group. He obtained his doctoral degree in environmental microbiology from Babasaheb Bhimrao Ambedkar University, Lucknow, India. In his doctoral work, Dr. Kumar successfully metabolized a widely used and hazardous insecticide Chlorpyrifos by cyanobacterial strain Oscillatoria sp. CYA8 CPF isolated from paddy fields.

    Dr. Sandhya Prajapati is currently working in the field of Solar photovoltaic applications. Dr. Prajapati has published various research papers "Energy Sources part A: Recovery, Utilization and Environmental Effects," International Journal of Renewable Energy Technology (Inderscience) and International Journal of Sustainable Engineering in load management, capacity credit and electric vehicle charging strategies. He obtained his doctoral degree in electrical engineering from Indian Institute of Technology, Roorkee, India. In his doctoral work, Dr. Prajapati successfully studied utilization of solar energy in various fields, especially in greywater recycling.
