The commercial PVF film TedlarÂȘ was first trademarked by DuPont 50 years ago. Since that time it has established itself as a polymer with excellent resistance to sunlight degradation (UV resistance), thermal stability, chemical attack, water absorption, and solvents. These properties, together with a high solar energy transmittance rate, have led to it becoming established worldwide as the number one choice for the backsheets of photovoltaic solar panels, and a fire-retardent coating used in aircraft. This book is the first and only handbook that describes polyvinyl fluoride preparation, technology, processing, fabrication and applications – making it essential reading for engineers and scientists working in industry sectors where PVF is utilized. Complete guide to the applications of polyvinyl fluoride in photovoltaics, aerospace, signage, etc. . Technology guide for processing and fabrication of PVF films. . Reference for properties and characteristics of PVF films . The only book available that focuses on PVF – properties, processing and applications.

Advanced Treatment Technologies for Fluoride Removal in Water Water Purification


Free Download Advanced Treatment Technologies for Fluoride Removal in Water: Water Purification by Akhilesh Kumar Yadav, Saba Shirin, Vijay P. Singh
English | PDF EPUB (True) | 2023 | 364 Pages | ISBN : 3031388445 | 40.6 MB
This book presents an overview of the techniques available today for the removal of fluoride contamination/pollutants/species from water. Also covered are traditionally applied techniques for the removal of fluoride pollutants/species, including oxidation, coagulation-flocculation, and membrane techniques. Recently, progress has been made on the utility of various nanoparticles for the extraction of contaminants from water. Fluoride contamination is affecting water resources quality worldwide as a result of human activities, such as mining and pesticide use. Due to the high risk of fluoride exposure, specific water treatment processes are required to meet more severe water quality standards. A better understanding of currently available processes is necessary to develop economical, efficient, and effective methods for fluoride removal. Fluoride can either be coated, adsorbed using a wide range of both mineral and organic constituents or can be directly rejected by membrane processes, such as reverse osmosis and nanofiltration. Recent developments of submerged hybrid membrane systems, such as membrane bioreactors in wastewater treatment, provide alternative technologies for fluoride treatment.
