Dear Patron, Greetings from Water Today!I am working on the December 2017 issue and would like to invite you to contribute technical articles, case studies, research papers on “An Overview Of Filtration Technologies & Filtration Systems” and facilitate a comprehensive perspective on the same. Please find below the theme note and do let us know if you could send us your article.Theme note - An Overview Of Filtration Technologies & Filtration Systems – December 2017 issueWater filtration technology has been evolved from the simple cloth sieving to today’s acoustics and nanotube technology. Filtration technology can be categories as conventional and non-conventional. The technology is an integral component of drinking water and wastewater treatment applications. It is, however, but one unit process within a modern water treatment plant scheme, whereby there are a multitude of equipment and technology options to select from depending upon the ultimate goals of treatment. To understand the role of filtration, it is important to make distinctions not only with the other technologies employed in the cleaning and purification of industrial and municipal waters, but also with the objectives of different unit processes.Filtration generally requires the use of various chemicals also known as filter aids. These chemicals include those used in the process of coagulation, and to accelerate and enhance the particle sedimentation process, as well as to provide a pre-coat filter to enhance the suspended particle removal efficiency. Both an understanding of the physical and chemical forces involved in the filtration process are important to proper selection and operation of filters in wastewater treatment applications. While membrane filtration which is widely used in chemical and biotechnology processes, is already established as a valuable means of filtering and cleaning wastewater and industrial process water. Tubular and spiral membrane plants have begun to be used to filter impurities from drinking water in regions where conventional treatment proves to be uneconomical.Membrane filters perform two tasks: one they can be used to concentrate or recover valuable material while the process water is allowed to flow through the membrane. And second, they effectively remove contaminants from waste streams allowing the water to be recycled to the process or discharged to the drain or the river.Membranes can be used for different types of filtration applications. Although there are different methods of filtration that incorporate membrane technology, the most mature is pressure driven membrane filtration. Membrane filtration is a rapidly expanding field in water treatment. There are four basic pressure driven membrane filtration processes for liquid separations. These are, in ascending order of size of particle that can be separated: reverse osmosis, nanofiltration, ultrafiltration and microfiltration. Further, due to the diversity of applications in both industrial and municipal water filtration, it is vital to evaluate the feasibility of using membranes, selecting the most appropriate membrane type according to the treatment process. With these filter technologies, we have different options to choose from a complete understanding of the filtration needs is required to ensure the proper specification of a solution for a given application. Our December issue will be focusing on identifying various the filtration technologies & filtration systems and its application environment. We would like to invite you to share your experiences in the form of articles, technical papers and case studies with our readers. Please inform us of your intent to contribute at the earliest, so that we can evaluate the articles for the publication.
