Photo- and Electrochemical Water Treatment

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.

Prof. Halan Prakash, currently works as an Associate Professor at the Department of Chemistry in Birla Institute of Technology and Science, Pilani, (BITS-Pilani), K K Birla Goa Campus. Before joining BITS, he worked as JSPS fellow at Kyoto Pharmaceutical University, Japan, and Nara Institute of Science and Technology, Japan with Prof. Shun Hirota, (2005-2008) and also worked at Tata Institute of Fundamental Research (TIFR) Institute, Mumbai, India as a visiting fellow (postdoctoral, 2003-2005), with Prof. Shyamalava Mazumdar. He obtained his Ph.D. degree in the year 2003, in the area of Inorganic Photochemistry under the supervision of Prof. P. Natarajan, NCFUP, at the University of Madras, India. Prof. Prakash’s area of research includes Inorganic Photochemistry, Bioinorganic Chemistry, and Environmental Chemistry. His current research is focused on the development of novel advanced oxidation processes (AOPs) for the degradation of organic pollutants, as well as, inactivation of bacteria in water. He is associated with the Society of Environmental Chemistry and Allied Sciences (SECAS), India as an executive member, and he was the convener of the fourth International Conference on Advanced Oxidation Processes (AOP-2016), held at BITS, Pilani K K Birla Goa campus. Prof. Prakash has published more than 40 research articles in journals and conferences and two patents. He has acted as an Editor for special issue publications on topics related to water research. Prof. Halan Prakash, is the leader for the drinking water work package of the Department of Science and Technology sponsored Indo-EU multi-consortium “PANIWATER” project.
