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.
