Book Description
Globally, 2.1 billion people live without access to safe water, and about 159 million people collect their drinking water directly from surface water sources. This issue is particularly prominent in water-stressed areas, such as India, which has a rural population of around 700 million, 63 million of whom do not have access to clean water. Contaminants of Emerging Concern (CECs), of both a chemical and biological nature, are increasingly being detected in wastewater effluents around the world. Chemical CECs include pollutants such as pharmaceuticals and personal care products, pesticides, hormones, and endocrine disruptors, and biological CECs include antibiotic resistant bacteria, pathogenic protozoans, and viruses. New technologies to remove the contaminants from water are urgently needed and photochemical approaches offer an exciting array of possibilities. Covering chemical analysis, molecular biology methods and computational approaches important for the elucidation of mechanisms and evaluation of photochemical processes, this book presents advanced photochemical processes for the removal of CECs from water. Readers will find chapters on advanced photochemical treatment prototypes and pilot plants, and discussions on translation from lab to field-scale implementation. Examples include highly transparent materials, integrated membranes, adsorbents, and photocatalysts for enhancing the photochemical processes by direct sunlight induced reactions, photo-Fenton, and photo-electrochemical reactions. Discussing both the advantages and disadvantages of these technologies, this book is a great resource both for academics researching photocatalytic processes and for water treatment professionals.

Book Description
This reprint focuses on new trends in photo-electrocatalysis, specifically addressed to the remediation of wastewater and energy production. The remediation of wastewater, up to a level that is acceptable for discharge into receiving waterbodies, involves an ever-growing demand of energy, so effective and low-energy treatment processes are highly desirable. Among the other treatments, photo- and photo-electrochemical treatment processes may be considered as advanced oxidation processes (AOP), which are based on the generation of OH radicals, strong oxidizing agents able to indiscriminately degrade even the most persistent organic compounds. Photocatalysis and photo-electrocatalysis can be considered as effective methods for organic degradation, especially when the semiconductor is active in the range of visible light. Several results are presented on new morphologies and structures, which allow more photoactive, visibly responsive, and stable materials, as well as studies on combined processes in which photo- or photo-electrochemistry contribute to an increase in the sustainability of the whole process, lowering costs and achieving the most valuable final products. In view of the circular economy concept, microbial fuel cell systems are also considered as possible way to recover energy from organic pollutants contained in wastewater.
